Vinyl laurate

UsesVinyl laurate was used in the synthesis of laurate and stearate esters of corn starch. It was used as the acyl donor during synthesis of sucrose laurate esters catalyzed by Bacillus pseudofirmus AL-89 . Vinyl laurate was also used in the preparation of chirally deuterated benzyl chlorides.

UsesVinyl laurate can be used to synthesize the following:sucrose laurate esters from sucrose in organic solventspoly(vinyl laurate) (PVL)latexesporous conducting ‘‘soft′′ polymer foams which can be used as gas sensors

General DescriptionVinyl laurate is a clear, colorless to light yellow colored liquid. The flash point is 125°C. It forms aqueous colloidal microgel by copolymerization with N-isopropylacrylamide. The enzymatic acylation of Avicel cellulose with vinyl laurate, a solvent free reaction system, was studied.

PreparationA method for the preparation of vinyl laurate: In a 500-ml round-bottomed three-necked flask fitted with a thermometer, a reflux condenser and a gas inlet tube through which a stream of nitrogen is passed, place 206 g (2.4 moles) of freshly distilled vinyl acetate and 80 g (0.4 moles) of lauric acid. The lauric acid is dissolved by heating, and 1.6 g of mercuric acetate is added. The mixture is shaken by hand for approximately 30 minutes, and 0.15 ml of 100% sulphuric acid is added dropwise. The solution is heated under reflux for 3 hours, then 0.83 g of sodium acetate trihydrate is added to neutralise the sulphuric acid. The excess vinyl acetate is recovered by distillation at atmospheric pressure (vapour temperature approximately 70–80°C) until the pot temperature reaches 125°C. The distillation is completed at a pressure of 10 mm Hg or lower; after collecting a small amount of low-boiling-point material, redistillation yields 48–53 g (53–59%) of pure vinyl laurate.
