Abstract

FIELD: organic chemistry, urea derivatives. SUBSTANCE: synthesis is carried out from corresponding derivatives of diphenylmethane and urea in the presence of mineral acid - concentrated HSOin the medium of organic solvent - CHCOOH at 70-95 C at molar ratio diphenylmethane derivative: urea derivative: HSO: CHCOOH = 1:(51-77):(51-77):2.2. Diphenylcarbinol is used as diphenylmethane derivative. The yield of the end diphenylureas is up to 92% , period process is 3-4 h, temperature is decreased from 135-140 C to 70-95 C, diphenylmethylcarbinol is available reagent. EFFECT: simplified process. 4 tbl
