1. be used for synthesis type CH 2The method of the acrylate of=CH-COO-R, wherein R represents to comprise 1-18 carbon atom and alkyl that comprise heteroatoms nitrogen where necessary, is characterised in that in the first step, makes glycerol CH when an acidic catalyst exists 2OH-CHOH-CH 2OH stands dehydration reaction to obtain formula CH 2The propenal of=CH-CHO in second step, makes the propenal of formation like this be converted into vinylformic acid CH by catalyzed oxidation then 2=CH-COOH in the 3rd step, makes the acid that is produced by second step stand esterification by means of alcohol roh then, and wherein R has the implication that provides above.
