METHOD FOR PRODUCTION OF N-ISOROPYL-N′-PHENYL-P-PHENYLENE DIAMINE Russian patent published in 1996 - IPC

Abstract SU 1540226 A1

FIELD: organic chemistry. SUBSTANCE: method is carried out by alkylation of p-aminodiphenylamine with the help of acetone. The process takes place at 120-170 C and pressure 45-60 N′ in the presence of catalyst. Mentioned above catalyst contains 44-58 % of CuO and 56-42 % of kg/cm². EFFECT: simplifies the method. 2 tbl
