FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing (meth)acrylic esters (F) based on alcohols having at least one carbon-carbon triple bond, characterised by that at least one alcohol having at least one carbon-carbon triple bond of formula (1) 
where R1 denotes hydrogen, alkyl having 1-18 carbon atoms; alkyl having 2-18 carbon atoms, aryl having 6-12 carbon atoms, cycloalkyl having 5-12 carbon atoms, interrupted, if necessary, by one or more oxygen and/or sulphur atoms and/or one or more substituted or unsubstituted amino groups, or a 5-6-member heterocycl having oxygen, nitrogen and/or sulphur atoms, wherein said residues can be substituted with aryl, alkyl, aryloxy, alkyloxy, heteroatoms/or heterocycles, respectively, and R2 denotes alkylene having 1-20 carbon atoms, cycloalkylene having 5-12 carbon atoms, arylene having 6-12 carbon atoms, or alkylene having 2-20 carbon atoms interrupted by one or more oxygen and/or sulphur atoms and/or one or more substituted or unsubstituted amino groups and/or one or more cycloalkyl groups, -(CO)-, -O(CO)O, -(NH)(CO)O-, -O(CO)(NH)-, -O(CO)- or -(CO)O, where the names of the residues can be replaced with aryl, alkyl, aryloxy, alkyloxy, heteroatoms and/or heterocycles respectively, n is a whole number from 0 to 3, preferably from 0 to 2 and more preferably from 1 to 2 and X; for each i=0 to n can be independently selected from a group comprising -CH2-CH2-O-, -CH2-CH(CH3)-O-, -CH(CH3)-CH2-O-, -CH2-C(CH3)2-O-, -C(CH3)2-CH2-O-, -CH2-CHVin-O-, -CHVin-CH2-O-, -CH2-CHPh-O- and -CHPh-CH2-O-, preferably from a group comprising -CH2-CH2-O-, -CH2-CH(CH3)-O- and -CH(CH3)-CH2-O-, and more preferably CH2-CH2-O-, where Ph denotes phenyl and Vin denotes vinyl, wherein the hydroxy groups of the alcohol are primary or secondary, esterified in the presence of at least one enzyme (E) with (meth)acrylic acid or re-esterified with at least one (meth)acrylic ester (D).
EFFECT: use of the present method enables to obtain esters of an acid based on alcohols which have carbon-carbon triple bonds with good output and low colour indices.
