FIELD: chemical industry.

SUBSTANCE: invention relates to a method for producing a carbonate derivative, including the step of irradiating a non-catalytic composition containing halogenated methane, oxygen and a hydroxyl-containing compound with high-energy light. The molar ratio of the total amount of the compound containing the hydroxyl group to 1 mol of methyl halide is 0.05 or more. A compound containing a hydroxyl group is the formula (i) R¹-OH, and the resulting carbonate derivative corresponds to the formula (I) R¹-OC(=O)-OR¹, or a compound containing a hydroxyl group is the formula (ii) HO-R²-OH, and the organic carbonate is a compound containing a fragment with the formula (II-1) [-OR²-OC(=O)-], or a cyclic carbonate derivative corresponding to the formula (II-2) -OR²-OC(=O)-. R¹ is a monovalent, R² divalent organic group, which include a C_1-20 aliphatic hydrocarbon group, a C_3-20 cycloalkyl group, a C_6-32 aromatic hydrocarbon group, or a (poly)alkylene glycol monoalkyl ether group for R¹ or (poly)alkylene glycol group for R².

EFFECT: safe and effective method for producing polycarbonate even without the use of a base and a catalyst.
