FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing glycol aldehyde, involving reaction of formaldehyde with hydrogen and carbon monoxide in the presence of a catalyst composition, which is based on a) rhodium source, b) ligand with general formula R¹P-R² (I), where R¹ is a bivalent radical, which, together with the phosphorous atom to which it is bonded, is 2-phospha-1,3,5,7-tetraC_1-20alkyl-6,9,10-trioxatricyclo[3.3.1.1{3,7}]decile group, and where R² is a monovalent radical, which is chosen from an alkyl group, containing 4 to 34 carbon atoms or a radical with general formula: -R³-C(O)NR⁴R⁵ (II), where R³ represents methylene, ethylene, propylene or butylene, and R⁴ and R⁵ independently represent an alkyl group containing 1 to 22 carbon atoms, and c) anion source. The invention also relates to a catalyst composition used in the production of glycol aldehyde, and to a method of producing ethylene glycol from glycol aldehyde obtained using the described method.

EFFECT: easy conversion of formaldehyde to glycol aldehyde in the presence of a stable catalyst.
