A classic laboratory method involves Bouveault-Blanc reduction of ethyl laurate. [4] Dodecanol is used to make surfactants, which are used in lubricating oils, and pharmaceuticals. Millions of tons of sodium dodecylsulfate (SDS) are produced annually by sulfation of dodecyl alcohol: [6] SO 3 + CH 3 (CH 2) 10 CH 2 OH → CH 3 (CH 2) 10 CH 2 OSO 3 H
It is formed by the ethoxylation chemical reaction of dodecanol (lauryl alcohol) to give a material with 5 repeat units of ethylene glycol. Multilamellar vesicle formation [ edit ]
(However, PE only dissolves at temperatures well above 100 °C.) Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2, and thus ethyl acetate is likely to be a good solvent. Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2, and ethanol is likely to be the best solvent of those tabulated. However, the latter is polar ...
The branching in 2-ethyl-1-butanol makes it harder to crystallize due to packing disruption, which results in a very low freezing point. Esters of 2-ethyl-1-butanol are similarly effected and it therefore finds application as a feedstock in the production of plasticizers and lubricants, where its presence helps reduce viscosity and lower freezing points.
where m is the coefficient of the Gibbs adsorption. [3] Values of m are calculated using the Double layer (interfacial) models of Helmholtz, Gouy, and Stern. Substances can have different effects on surface tension as shown : No effect, for example sugar; Increase of surface tension, inorganic salts; Decrease surface tension progressively, alcohols
Typical reaction times vary from 1–10 hours at temperatures of 60–110 °C. Direct acylations of alcohols with carboxylic acids is preferred over acylations with anhydrides (poor atom economy of the reaction) or acid chlorides (moisture sensitive reagents).
Octyldodecanol is a branched-chain primary alcohol used as the isomer 2-octyl-1-dodecanol in cosmetics such as lipstick, [2] or as an anti-blooming agent in facepowder. [3] It is a medium spreading emollient, with equilibrium spreading pressure of 17.0 dyne/cm. [4] Octyldodecanol is in the class of Guerbet alcohols, because it has the branch at the β position. [5]
