METHOD OF SYNTHESIS OF SUBSTITUTED N-ALKYL-p- NITROSODIPHENYL AMINES Russian patent published in 1999 - IPC

Abstract RU 2139274 C1

FIELD: rubber processing industry. SUBSTANCE: substituted N-alkyl-p- nitrosodiphenyl amines of formula I: CH₃ or C₂H₅ wherein R is HNR¹R² are synthesized by polycondensation of isonitrogoacetyl acetone with acetone and N-alkylaniline R¹=R²CH₂CH₂OH wherein (a) R¹=CH₃, (b) R²=C₆H₅, R¹=C₂H₅, (c) R²=C₆H₅, in the presence of dehydrating agents. Compounds are useful as modifiers and stabilizers of rubber mixes and as vulcanizing agents for improving physical-mechanical properties of rubbers. EFFECT: more efficient synthesis method. 2 ex
