Bis[3-(3,5-dialkyl-4-hydroxyphenyl)propyl]mono- and disulfides as the Sevilen stabilizers
摘要:
The effect of the shielding degree of the phenol hydroxy group on the hydrolytic and thermal stability of ethylene-vinyl acetate copolymer (Sevilen) was studied on a series of phenols containing one or two sulfur atoms in the aliphatic chain of the para-substituent. Among the synthesized compounds a group of disulfides was found with a high antioxidant efficiency, which increase the Sevilen hydrolytic stability. The most effective are the 6-tert-butyl-2-methylphenol derivatives.

The reaction of ω-(4-hydroxyaryl)haloalkanes with various nitrogen-containing agents afforded primary, secondary, and tertiary amino derivatives of 2,6-dialkylphenols. For the compounds synthesized, the reaction rate constants with peroxide radicals were measured for cumene and methyl oleate oxidation. The total inhibitory activity in the model reactions of thermal autooxidation of lard and hexadecane was studied. The rate constants of alkyl(hydroxylaryl)amines are the same as those of the corresponding alkylphenols, whereas the total inhibitory activity of some alkyl(hydroxylaryl)amines exceeds substantially that for alkylphenols.

The reaction of omega-(3,5-dialkyl-4-hydroxyphenyl)-1-chloroalkanes with sodium sulfide yielded the corresponding sulfides, which were tested as antioxidants in two model reactions: oxidation of lard and Vaseline oil.
