Abstract
1,264,265. Stabilizing 2,5-dimethylhexadienes. SUMITOMO CHEMICAL CO. Ltd. 4 March, 1970 [13 March, 1969 (2)], No. 10519/70. Heading C5E. 2,5-dimethylhexadienes are stabilized by adding at least 0À05 wt. per cent, preferably 0À05- 1 wt. per cent of at least one tertiary butyl phenol or secondary amine. Stabilizers which are added to the 2,4 and 1,5 diene are:-3,5 di-tbutyl-4-hydroxy toluene, a mixture of 2- and 3 - t-butyl-4-methyl phenol, 2,2<SP>1</SP>-methylene-bis-(6- t-butyl methyl phenol), 4,4<SP>1</SP>-thio-bis-(6-t-butyl- 3-methyl phenol), 4,4<SP>1</SP>-butylene-bis-(6-t-butyl-3- methylphenol), N,N<SP>1</SP>-di-sec-butyl-p-phenylenediamine, phenyl α- or #-naphthylamine, N,N<SP>1</SP>- diphenyl (or dioctyl or di-#-naphthyl)-p-phenylene diamine, N-phenyl, N<SP>1</SP>-isopropyl-p-phenylene diamine, and 6-ethoxy-2,2,4-trimethyl-1,2- dihydroquinoline.
