Abstract

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to preparing lactones that are used as inhibitors of metal corrosion, for preparing antioxidants for hydrocarbon fuels and lubricants. Method is carried out by catalytic oxidation of diols. Carbon tetrachloride is used as an oxidant. Process is carried out in the presence of vanadium catalysts V2O5, VCl4. VO(acac)2, at temperature 100-150 C for 1-3 h, in the mole ratio [V] :[diol]:[CCl4] = 1:(200-500):(500- 2000), respectively. Invention provides the enhancement of purity of end product, reduced consumption of catalyst and amount of organic waste. EFFECT: improved preparing method. 1 tbl, 15 ex
