FIELD: organic chemistry, biotechnology. SUBSTANCE: method of synthesis of acrylic acid esters and C1-C8-aliphatic alcohols involves preparing acrylamide from acrylonitrile using biomass of the strain Rhodococcus rhodochrous M8 or M33, hydrolysis of acrylamide in the presence of sulfuric acid at molar ratio acrylamide : sulfuric acid = 1:(0.5-1.0), extraction of acrylic acid with the corresponding alcohol or ether or alcohol with ether followed by esterification of acrylic acid and isolation of the end product by the known procedure. EFFECT: decreased formation of by-side substances, increased yield of the end product.
