METHOD OF RECYCLING 2-CHLORO-1-PHENYLETHANOL-1

摘要

FIELD: chemistry. ^ SUBSTANCE: present invention relates to a method of recycling 2-chloro-1-phenylethanol-1, an irritant substance, in order to obtain a highly effective rodenticide - 2,2-bis(2-oxo-2-phenylethoxy)indandione-1,3 which can be used in agriculture for rodent control. The method involves reacting 2-chloro-1-phenylethanol-1 with ninhydrin in an acetone medium in the presence of potassium carbonate. As a rule, the reaction is carried out at 50-60C for 4-5 hours. ^ EFFECT: increased efficiency of recycling 2-chloro-1-phenylethanol-1. ^ 2 cl, 3 tbl, 1 dwg, 1 ex
