ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), N-dodecyl mercaptan, which has a vapor pressure of 8.53X10-3 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase N-dodecyl mercaptan is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 7 hours(SRC), calculated from its rate constant of 5.5X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). N-dodecyl mercaptan does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

The rate constant for the vapor-phase reaction of N-dodecyl mercaptan with photochemically-produced hydroxyl radicals has been estimated as 5.5X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 7 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). A half-life of 100 days was reported for N-dodecyl mercaptan reaction with ozone(2). N-dodecyl mercaptan is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(3). N-dodecyl mercaptan does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
An estimated BCF of 360 was calculated for N-dodecyl mercaptan(SRC), using an estimated log Kow of 6.18(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC), provided the compound is not metabolized by the organism(SRC).
Using a structure estimation method based on molecular connectivity indices(1), the Koc of N-dodecyl mercaptan can be estimated to be 1.1X10+4(SRC). According to a classification scheme(2), this estimated Koc value suggests that N-dodecyl mercaptan is expected to be immobile in soil.

This paper investigates the effect of n-dodecyl mercaptan (n-DDM) as a chain transfer agent on the molecular weight of poly(methyl methacrylate). The transfer constant of n-Dodecyl mercaptan was calculated at different temperatures; the activation energy and frequency factor for an Arrhenius equation of transfer constant were then obtained.

Kinetics of the styrene emulsion polymerization using n‐dodecyl mercaptan as chain‐transfer agent
The kinetics of the styrene emulsion polymerization using n‐dodecyl mercaptan as chain‐transfer agent was studied. n‐dodecyl mercaptan was found that the chain‐transfer agent (CTA) had no effect on polymerization rate but substantially affected the molecular weight distribution (MWD). The efficiency of the CTA in reducing the MWD was lowered by the mass‐transfer limitations. The process variables affecting CTA mass transfer were investigated. A mathematical model for the process was developed. The outputs of the model include monomer conversion, particle diameter, number of polymer particles, and number‐average and weight‐average molecular weights. The model was validated by fitting the experimental data.

Polymerization of methyl methacrylate by 2‐pyrrolidinone and n‐dodecyl mercaptan
The bulk polymerization of methyl methacrylate initiated with 2‐pyrrolidinone and n‐dodecyl mercaptan (R‐SH) has been explored. This polymerization system showed “living” characteristics; for example, the molecular weight of the resulting polymers increased with reaction time by gel permeation chromatographic analysis. Also, the polymer was characterized by Fourier transform infrared spectroscopy, 1H NMR, and 13C NMR techniques. The polymer end with the iniferter structures was found. By the initial‐rate method, the polymerization rate depended on [2‐pyrrolidinone]1.0 and [R‐SH]0. Combining the structure analysis and the polymerization‐rate expression, a possible mechanism was proposed. n‐Dodecyl mercaptan served dual roles—as a catalyst at low conversion and as a chain‐transfer agent at high conversion. Finally, the thermal properties were studied, and the glass‐transition temperature and thermal‐degradation temperature were, respectively, 25 and 80–100 °C higher than that of the azobisisobutyronitrile system.
General description of N-dodecyl mercaptan
1-Dodecanethiol (DDT) is an alkyl thiol that forms a self-assembled monolayer (SAM) and can be used as an organic source of sulfur with balanced physio-chemical properties.

Application of N-dodecyl mercaptan
N-dodecyl mercaptan (DDT) can be used as a source of sulfur for the synthesis CdS quantum dots (QDs) and lead sulfide nanoparticles (PbS) which find potential applications in energy efficient lighting, solar cells and as ammonium gas sensing agents. N-dodecyl mercaptan may be used to form a self-assembled monolayer (SAM) on copper surface as a corrosion resistant coating. [6]Functionalization with DDT may form SAMs on geranium (Ge) to improve the surface characteristics for futuristic applications in microelectronics.
N-Dodecyl mercaptan's production and use in pharmaceuticals, insecticides, nonionic detergents, synthetic rubber processing, and as a froth flotation agent for metal refining may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 8.53X10-3 mm Hg at 25 °C indicates n-Dodecyl mercaptan will exist solely as a vapor in the ambient atmosphere. Vapor-phase n-Dodecyl mercaptan will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 7 hours. n-Dodecyl mercaptan does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, n-Dodecyl mercaptan is expected to be immobile based upon an estimated Koc of 1.1X10+4. Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law constant of 5.9X10-2 atm-cu m/mole. However, adsorption to soil is expected to attenuate volatilization. Biodegradation data were not available. If released into water, n-Dodecyl mercaptan is expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is expected to be an important fate process based upon this compound's estimated Henry's Law constant. Estimated volatilization half-lives for a model river and model lake are 4 hours and 6 days, respectively. However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 77 days if adsorption is considered. An estimated BCF of 360 suggests the potential for bioconcentration in aquatic organisms is moderate. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to n-Dodecyl mercaptan may occur through inhalation and dermal contact with this compound at workplaces where n-Dodecyl mercaptan is produced or used. The greatest potential for dermal and inhalation exposure to n-Dodecyl mercaptan is expected at the packing station at the manufacturing site and to a lesser extent during activities at the consumer site.

Reactivity Profile n-dodecyl mercaptan is incompatible with bases, oxidizing agents, reducing agents and alkali metals. Easily oxidized to disulfide.

N-dodecyl mercaptan is commonly used as a chain transfer agent in the manufacturing process of styrene/butadiene latex for use in carpet and paper industries. A gas chromatographic technique has been successfully developed for the measurement of n-dodecyl mercaptan based on its sulfur content for material identification, trend analysis, or for the monitoring of un-reacted residual material in final products. The method employs low thermal mass gas chromatography (LTM-GC) and a dual-plasma sulfur chemiluminescence detector (DP-SCD) to attain a high degree of sensitivity and selectivity. Using the technique described, a detection limit in the range of 0.5 ppm (v/v) n-dodecyl mercaptan and less than 1 min analysis time can be achieved. Response is linear over four orders of magnitude with high degree of repeatability of less than 5% RSD.

In the process of manufacturing latex such as styrene-butadiene, a chain transfer agent is required. The chain transfer agent assists in the polymerization to make products of the desired molecular distribution. Previously, chlorinated compounds such as carbon tetrachloride and chloroform have been used for this application, but because of their toxicity and negative environmental effects, it is no longer a practice to employ said compounds for the manufacturing of latex used for the carpet and paper industries. Instead, use of n-dodecyl mercaptan is preferred for the applications described. As a result of the world demand for latex and the magnitude of the associated industries, n-dodecyl mercaptan has become a chemical of industrial significance. From a manufacturing standpoint, n-dodecyl mercaptan is a mixture of isomeric thiols produced from oligomers of propylene tetramer orsometimes, isobutylene trimer. Propylene tetramer is produced by oligomerization of propylene in the presence of a FriedelCrafts type catalyst such as sulfuric acid. n-dodecyl mercaptan is produced by passing hydrogen sulfide and either propylene tetramer orisobutylene trimer over a catalyst such as boron trifluoride (1,2).
Because of the fact that there are many permutations of thetetramer structure, and hence the location of the –C=C– bond, the thiol group can be located in many different positions,
resulting in a product mixture of isomers with an average boiling point range around 230°C.

Recently, there has also been some increased concerns regarding to the accumulation of n-dodecyl mercaptan in the environment (3,4). The open literature contains little to no information on the analysis of n-dodecyl mercaptan. This is partly due to the fact that the matrix can be quite complex. An example would be water soluble emulsion polymer, comprizing hundreds of components which can cause chromatographic interference. Also, alkyl mercaptans such as n-dodecyl mercaptan are difficult to analyze due to reasons such as the alkyl chains are C8 to C15 in size and cover a wide range of boiling points, the polarity of the individual components in n-dodecyl mercaptan varies with the degree of thiolation, the location of the R-SH moiety. In addition to the differences in polarity and boiling points of the n-dodecyl mercaptan components, the product can also contain a fraction of relatively non-polar, non-thiolated tetramer. For the measurement of n-dodecyl mercaptan, an internal method involves the use of headspace gas chromatography in combination with flame photometric detection (FPD) had been developed (5). The method, however, has its constraints, including competing vapour–liquid equilibrium of solutes in the sample and the lack of linear dynamic range of the FPD.
As a result, a new chromatographic method is required for raw material identification of n-dodecyl mercaptan, for trend analysis, and for the monitoring of residual material in the final products.

The new chromatographic method was developed with three enablers:

(i) Liquid–liquid extraction to remove n-dodecyl mercaptan isomers from their respective matrices;

(ii) Low thermal mass gas chromatography to deliver the flexibility of either speciation of individual sulfur compounds, or peak compression to combine individual sulfur compounds into one discreet peak with high temperature programming capability and to improves overall sample to sample throughput;

(iii) Dual plasma sulfur chemiluminescence detector (DP-SCD) to offer the highest degree of selectivity for n-dodecyl mercaptan isomers, equi-molar response and a respectable linear dynamic range.

*These clusters were further used for the production of monodisperse Au nanoparticles with controlled surface properties through ligand exchange with 1-dodecanethiol or 1-decylamine

A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. The n-dodecyl mercaptan molecule contains a total of 38 bond(s) There are 12 non-H bond(s), 10 rotatable bond(s) and 1 thiol(s).
The 2D chemical structure image of n-dodecyl mercaptan is also called skeletal formula, which is the standard notation for organic molecules. The carbon atoms in the chemical structure of n-dodecyl mercaptan are implied to be located at the corner(s) and hydrogen atoms attached to carbon atoms are not indicated – each carbon atom is considered to be associated with enough hydrogen atoms to provide the carbon atom with four bonds.

The 3D chemical structure image of n-dodecyl mercaptan is based on the ball-and-stick model which displays both the three-dimensional position of the atoms and the bonds between them. The radius of the spheres is therefore smaller than the rod lengths in order to provide a clearer view of the atoms and bonds throughout the chemical structure model of n-dodecyl mercaptan.
