Synthesis and study of carbamide derivatives of the 2,6-di-tert-butylphenol type as antioxidants

Abstract

Carbamide derivatives of 2,6-di-tert-butylphenol were synthesized by the reaction of N,N-di(3,5-di-tert-butyl-4-hydroxyphenyl)carbamoylchloride with amines. A study was made of the effect of compounds synthesized on the anti-oxidizing stability of T-6 jet fuel. It was shown that inhibiting action is determined by the type of substitution at the nitrogen atom. N,N-di-(3,5-di-tert-butyl-4-hydroxyphenyl)-N'-tert-butylcarbamide has the highest anti-oxidizing action, compared with other carbamide derivatives and ionol. (JMT)
