FIELD: chemistry.
SUBSTANCE: invention relates to basic organic synthesis and a method of producing ethylene glycol together with carbamide from carbon dioxide, ethylene oxide and ammonia. The method involves carrying out the process in two steps: first, reaction of carbon dioxide and ethylene oxide at temperature 80-150°C, pressure 2.1-6 MPa in the presence of a homogeneous catalyst - complex of zinc bromide with tertiary organophosphines with subsequent extraction of ethylene carbonate, followed by ammonolysis of ethylene carbonate in a single process step in ether-type solvents which partially dissolve carbamide, at temperature 120-170°C and pressure 2.8-6 MPa to obtain ethylene glycol and carbamide.
EFFECT: method enables virtually complete conversion of starting material to the end products, and also considerably lowers power consumption due to improvement of the process of separating ethylene glycol and carbamide.
