An epidemiological survey of the effects of occupational exposure to allyl chloride was conducted. The study group consisted of 53 workers, (39 female) aged 18 to 51,
working in two factories in the Peoples Republic of China that manufactured sodium allyl sulfonate. The subjects were given detailed questionnaires about their
occupational and medical histories. Physical and neurological examinations were administered. Electroneuromyographic measurements were made. Ambient air concentrations
of allyl chloride were measured. Allyl chloride concentrations ranged from 2.6 to 6,650 and 0.2 to 25.13 mg/cu m in the two factories. The factory with the lower
allyl chloride concentrations was newer. The durations of exposure of the subjects in the older and newer factories were 2.5 months to 6 years and 1 to 4.5 years,
respectively. More tan 92% of the subjects in the older factory reported weakness in the extremities. Other symptoms reported included paraesthesia and numbness in the
extremities. Electroneuromyograph showed a neuropathy prevalence of 52.6%. In the newer factory, approximately 67% of the subjects reported weakness in the extremities.
Other reported symptoms included numbness of hands and feet and dizziness. the number of subjects with abnormal neurological signs was smaller in the newer factory.
Forty eight percent of the workers had electroneuromyograch findings indicating mild neuropathy. No significant abnormalities of other organs were noted. It was
concluded that the main risk of industrial exposure to allyl chloride is damage to the peripheral nervous system. Polyneuropathy is thought to be the main
clinical manifestation of chronic allyl chloride exposure.

Applications of Sodium allyl sulfonate
Hydrotropes are in Sodium allyl sulfonate use industrially and commercially in cleaning and personal care product formulations to Sodium allyl sulfonate allow more concentrated formulations of surfactants. About 29,000 metric tons are produced (i.e., manufactured and imported) annually in the US. Annual production (plus importation) in Europe and Australia is approximately 17,000 and 1,100 metric tons, respectively.Common products containing a Sodium allyl sulfonate hydrotropes include laundry detergents, surface cleaners, dishwashing detergents, liquid soaps, shampoos and conditioners. They are coupling agents, used at concentrations from 0.1-15% to stabilize the formula, modify viscosity and cloud-point, reduce phase separation in low temperatures, and limit foaming.
Environmental Considerations Sodium allyl sulfonate
Hydrotropes have a low bioaccumulation potential, as the octanol:water partition coefficient is <1.0. Studies have found hydrotopes to be very slightly volatile, with vapor pressures <2.0x10-5 Pa. They are aerobically biodegradable. Removal via the secondary wastewater treatment process of activated sludge is >94%. Acute toxicity studies on fish show an LC50 >400 mg active ingredient/L. For Daphnia, the EC50 is >318 mg a.i./L. The most sensitive species is green algae with EC50 values in the range of 230-236 mg a.i./ L and No Observed Effect Concentrations (NOEC) in the range of 31-75 mg a.i./L. The aquatic Predicted No Effect Concentration (PNEC) was found to be 0.23 mg a.i./L. The Predicted Environmental Concentration (PEC)/PNEC ratio has been determined to be < 1 and, therefore, hydrotropes in household laundry and cleaning products have been determined to not be an environmental concern.Aggregate Sodium allyl sulfonate Sodium allyl sulfonate exposures to consumers (direct and indirect dermal contact, ingestion, and inhalation) have been estimated to be 1.42 ug/Kg bw/day.
Calcium xylene sulfonate and Sodium allyl sulfonate have been shown to cause temporary, slight eye irritation in animals. Studies Sodium allyl sulfonate have not found hydrotropes to be mutagenic, carcinogenic or have reproductive toxicity. Cumene (isopropylbenzene) is an organic compound that Sodium allyl sulfonate is based on an aromatic hydrocarbon with an aliphatic substitution. It is a constituent of crude oil and refined fuels. It is a flammable Sodium allyl sulfonate colorless liquid that has a boiling point of 152 °C. Nearly all the cumene that is produced as a pure compound Sodium allyl sulfonate on an industrial scale is converted to cumene hydroperoxide, which is an intermediate in the synthesis of other industrially important chemicals, primarily phenol and acetone. Commercial production of cumene is by Friedel-Crafts alkylation of benzene with propylene. Cumene producers account for approximately 20% of the global demand for benzene. The original Sodium allyl sulfonate route for manufacturing of cumene was by alkylation of benzene in the liquid phase using sulfuric acid as a catalyst, but because of the complicated neutralization and recycling steps required, together with corrosion problems, this process has been largely replaced. As an Sodium allyl sulfonate alternative, solid phosphoric acid (SPA) supported Sodium allyl sulfonate on alumina was used as the catalyst. Adenosine triphosphate (ATP) has been shown to be a hydrotrope able to prevent aggregation of proteins at normal physiologic concentrations and to be approximately an order of magnitude more effective than sodium xylene Sodium allyl sulfonate sulfonate in a classic hydrotrope assay. The hydrotrope activity of ATP was shown to be independent of its activity as an "energy currency" in cells. Recently, ATP Sodium allyl sulfonate function as biological hydrotope has been shown proteome-wide under near native conditions.

The material Sodium allyl sulfonate also shows detergency.Sodium allyl sulfonate is a solubilizer, coupling agent and cloud point depressant used in heavy duty cleaners, wax strippers and dishwashing detergents, oil field and metal working applications.
Sodium allyl sulfonate (conjugate base benzenesulfonate) is an organosulfur compound with the formula C6H6O3S. It is the simplest aromatic sulfonic acid. It forms white deliquescent sheet crystals or a white waxy solid that is soluble in water and ethanol, slightly soluble in benzene and insoluble in nonpolar solvents like diethyl ether. It is often stored in the form of alkali metal salts. Its aqueous solution is strongly acidic.
Preparation of Sodium allyl sulfonate
Sodium allyl sulfonate is prepared from the sulfonation of benzene using concentrated sulfuric acid:
Aromatic sulfonation of benzene
This conversion illustrates aromatic sulfonation, which has been called "one of the most important reactions in industrial organic chemistry".
Reactions of Sodium allyl sulfonate
Sodium allyl sulfonate exhibits the reactions typical of other aromatic sulfonic acids, forming sulfonamides, sulfonyl chloride, and esters. The sulfonation is reversed above 220 °C. Dehydration with phosphorus pentoxide gives Sodium allyl sulfonate anhydride ((C6H5SO2)2O). Conversion to the corresponding benzenesulfonyl chloride (C6H5SO2Cl) is effected with phosphorus pentachloride.
It is a strong acid, being almost fully dissociated in water.
Sodium allyl sulfonate and related compounds undergo desulfonation when heated in water near 200 °C. The temperature of desulfonation correlates with the ease of the sulfonation:
C6H5SO3H + H2O → C6H6 + H2SO4
Because of that, sulfonic acids are usually used as a protecting group, or as a meta director in electrophilic aromatic substitution.
The alkali metal salt of Sodium allyl sulfonate was once used in the industrial production of phenol. The process, sometimes called alkaline fusion, initially affords the phenoxide salt:
C6H5SO3Na + 2 NaOH → C6H5ONa + Na2SO3
C6H5ONa + HCl → C6H5OH + NaCl
The process has been largely displaced by the Hock process, which generates less waste.
Uses of Sodium allyl sulfonate
Sodium allyl sulfonate is commonly used as the active ingredient in laundry detergent used in clothes washing machines.
Sodium allyl sulfonate is often used to convert to other specialty chemicals.
A variety of pharmaceutical drugs are prepared as benzenesulfonate salts and are known as besilates (INN) or besylates (USAN).
In a diluted form, it is also used as a polymer remover stripping agent.
Sodium allyl sulfonate's use as a reagent in the manufacture of phenol, resorcinol, and other organic syntheses and as a catalyst could result in its release to the environment through various waste streams. Sodium allyl sulfonate is expected to have very high mobility in soil. Volatilization of Sodium allyl sulfonate is not expected from either moist or dry soils. In water, Sodium allyl sulfonate is expected to be essentially non-volatile. Adsorption to sediment, bioconcentration, and hydrolysis are not expected to be important fate processes in aquatic systems. Biodegradation of Sodium allyl sulfonate is likely to occur in both aquatic and soil media provided adequate acclimation by microorganisms occurs. Sodium allyl sulfonate will exist in both the vapor and particulate phases in the ambient atmosphere. If released to the atmosphere, it will degrade by reaction with photochemically produced hydroxyl radicals with an estimated half-life of approximately 29 days. Removal of Sodium allyl sulfonate from the atmosphere can occur though wet and dry deposition. Exposure to Sodium allyl sulfonate can occur through dermal contact, inhalation, and ingestion.
Based on a recommended classification scheme, Sodium allyl sulfonate should have very high mobility in soil based on estimated Koc values ranging from 1.4 to 12. Biodegradation of Sodium allyl sulfonate is likely to occur in soil media provided adequate acclimation by microorganisms occurs. Volatilization of Sodium allyl sulfonate is not expected from either moist or dry soils based on an estimated vapor pressure of approximately 2.36X10-5 mm Hg at 25 °C and an estimated Henry's Law constant of 2.52X10-9 atm-cu m/mole.
Decomposition of Sodium allyl sulfonate took 16 days by a soil microflora inoculum in mineral salts medium. Sodium benzenesulfonate had a 5-day theoretical BOD (at 20 °C) of 2.6, 74.5, and 38.8% in sewage seed, acclimated activated sludge seed, and by the Warburg technique with acclimated activated sludge, respectively. A biodegradation study using 100 mg/l Sodium allyl sulfonate, consumed 62, 58, and 344 ul oxygen in an endogenous control, Sodium allyl sulfonate adapted cells, and benzenesulonic acid and phenol adapted cells, respectviely, in 230 minutes. In a 2 week closed bottle study, with 100 mg/l Sodium allyl sulfonate and 30 mg/l sludge, Sodium allyl sulfonate gave a theoretical BOD of 87%. Sodium allyl sulfonate utilized 10.7 mg of TOC/g of mixed liquor volatile suspended solids per hour in acclimated activated sludge, indicating that the activated sludge possessed the necessary catabolic enzymes required for degradation.
The sulfonated benzene structure appears to offer no real resistance to bacterial breakdown since BOD tests carried out on this structure in dilute solutions in river water result in considerable oxygen depletion. Sodium allyl sulfonate is resistant to chemical oxidation by KMnO4 and to biochemical oxidation under conditions of 5 day BOD determination. Under conditions of dichromate COD determination, oxidation of Sodium allyl sulfonate amounts to 94%. Sodium allyl sulfonate is deemed degradable by the Japanese MITI test. Sodium allyl sulfonate allowed visible growth of 12 of 14 species of phenol- utilizing bacteria after 5 days at 30 °C. Sodium allyl sulfonate degraded only about 4% after 13 months in aquifer slurries from both sulfate reducing and methanogenic sites. A study on oxidation of selected carcinogenic compounds (including sodium benzenesulfonate) by activated sludge found no significant oxidation for any compounds studied. The presence of a sulfonate grouping on benzene greatly reduces the susceptibility of Sodium allyl sulfonate to biological oxidation. Sodium allyl sulfonate was degraded with difficulty, if at all, in aniline-acclimated activated sludge.

A new type of single‐ion conducting polymer electrolyte for lithium‐ion batteries, poly(hexafluorobutyl methacrylate‐co‐lithium allyl sulfonate) (P (HFMA‐co‐ASLi)), was firstly prepared by copolymerizing hexafluorobutyl methacrylate (HFMA) and sodium allyl sulfonate (SAS) with a subsequent lithiation process. The prepared polymer electrolyte exhibits high lithium ionic conductivity (10−4 S cm−1 at 80 °C) and excellent cycle performance at high temperature, which could be attributed to the good
thermal stability (remains stable up to 300 °C), mechanical properties (7.1 MPa for breaking strength) and high lithium‐ion transference number (0.92). The
electrolyte also displays good electrochemical stability (4.6 V). Our obtained results prove that the polymer P (HFMA‐co‐ASLi) is a promising candidate electrolyte for lithium‐ion batteries
