FIELD: obtaining esters of carboxylic acids.
SUBSTANCE: method for producing di-(2-ethylhexyl) ester of azelaic acid includes the process of interaction of azelaic acid with 2-ethylhexyl alcohol in the presence of a catalyst; the process is characterized by using a biocatalyst as a catalyst; the following biocatalysts may be used as a catalyst: biocatalyst immobilized on a macroporous polymer, the producer of which is the yeast of the genus Candida antarctica, or biocatalyst, the producer of which is the mycelial fungi Thermomyces lanugiosus, or biocatalyst, the producer of which is the mycelial fungi Rhizomucor miehei, or biocatalyst KF 3.1.1.3.
EFFECT: invention provides reduction of energy costs, high yield of the target product, high purity of the target product, absence of monoesters and side processes, reuse of the biocatalyst.
