LAURYL ALDEHYDE(Dodecanal)

CAS Number:112-54-9
Molecular Formula:C12H24O
Molecular Weight:184.32

Dodecanal, also known as lauraldehyde or dodecyl aldehyde, is an organic compound with the chemical formula CH3(CH2)10CHO. This colourless liquid is a component of many fragrances.
Lauryl aldehyde occurs naturally in citrus oils, but commercial samples are usually produced from dodecanol by dehydrogenation.

-Uses-
Lauryl aldehyde is a fragrance agent that is found in soaps, perfumes as well as in food flavoring materials.

-Processing of Lauryl aldehyde-
Melt crystallization is a technically proven and selective separation method for obtaining pure isomeric compounds.
Nonetheless, a separation of isomeric long-chain aldehydes has not yet been realized by melt crystallization.
Existing methods often use chemical reactions or require additives.
In this work, we evaluated the feasibility of the purification of dodecanal from the isomeric long-chain mixture dodecanal/2-methylundecanal (C12H24O) with melt crystallization.
For this purpose, the binary solid–liquid equilibrium of dodecanal/2-methylundecanal was measured with differential scanning calorimetry.
The liquidus line of the binary system can be calculated using only the melting temperature and the enthalpy of fusion of dodecanal.
On the basis of the solid–liquid equilibrium, layer melt crystallization experiments under an inert gas atmosphere were conceived.
Depending on the process conditions (feed concentration and cooling rate), the growth rates of the crystalline layer were measured online, and crystal purities were determined as a function of the growth rate and melt concentration.
Furthermore, the efficiency of sweating as a finishing treatment was investigated.
To model the crystalline layer thickness, a site-specific heat flow balance at the crystal surface and a space- and the time-dependent enthalpy balance of the crystal volume were applied.
The model is able to describe the crystallization process adequately, depending on the process parameters.

-General Info-
At high concentrations, the defensive tergal gland secretion (TGS)3 of the staphylinid beetle,Aleochara curtula, inhibits the male copulatory response (grasping with parameres). Inhibitory chemicals, for which a function as alarm substances is assumed, aren-undecane, 1-undecene,n-dodecanal, toluquinone, and 2-methoxy-3-methyl-1,4-benzoquinone.
When emitted in small amounts, however, the TGS releases the male grasping response.
The main components with aphrodisiac effect are (Z)-4-tridecene,n-dodecanal, and (Z)-5-tetradecenal. These supplementary mating stimulants, which are not sex specific, work synergistically with the aphrodisiac female sex pheromone from thé epicuticular lipids and are discussed as alerting pheromones of short-term effect.
Antennal movements of resting males as an indication of the recognition of a female and the approach to the mate are released at somewhat longer distances, when the TGS is additionally present.

-Application-
Lauryl aldehyde is may be used to investigate the thermal properties of caprylic acid using differential scanning calorimetry.
Lauryl aldehyde may also be used as extraction solvent during determination of five kinds of polycyclic aromatic hydrocarbons in water samples, using dispersive liquid-liquid microextraction based on solidification of floating organic droplet method (DLLME-SFO).
