METHOD FOR SYNTHESIS OF BIORESOURCE ACRYLIC ESTERS Russian patent published in 2014 - IPC C07C69/54 C07C213/06 C07C219/08 C07C45/52 B01J23/28 B01J23/30 B01J31/10 C07C67/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing an acrylic ester of formula CH₂=CH-COO-R, in which R denotes an alky radical, straight or branched, containing 1-18 carbon atoms and optionally a nitrogen heteratom, wherein at the first step glycerine CH₂OH-CHOH-CH₂OH is dehydrated in the presence of an acid catalyst to obtain acrolein of formula CH₂=CH-CHO, then a second step where the obtained acrolein is converted via catalytic oxidation to acrylic acid CH₂=CH-COOH, a third step where the acid obtained at the second step is either esterified with an alcohol R₀OH, wherein R₀ is CH₃, C₂H₅, C₃H₇ or C₄H₉, followed by re-esterification of the obtained ester with an alcohol ROH, wherein R assumes the value given above, or esterified with an alcohol ROH, wherein R assumes said value, where content of furfural in the acrylic ester is less than 3 ppm.

EFFECT: high efficiency of the method.
