Abstract

Bis-3,5,5-trimethylhexanoyl peroxide is prepared, free from smell precursors, from a 3,5,5-trimethylhexanoic acid which contains less than 0.2% by weight of its C8-C10 isomers and/or homologues having at least 5 carbon atoms in a straight chain, any side chains being methyl and/or ethyl groups. Examples describe the purification of 3,5,5-trimethylhexanoic acid from the dimerization, carbonylation, and oxidation of isobutene, by esterification to the methyl ester, followed by fractional distillation and hydrolysis to acid, and by the oxidation of 3,5,5-trimethyl hexanol with sodium hydroxide followed by acidification of the sodium salt to yield a free acid which is dried and distilled. Peroxides are formed by treatment of 3,5,5-trimethylhexanoyl chloride with hydrogen peroxide solution. Reference has been directed by the Comptroller to Specification 879,625.ALSO:Dinonanoyl peroxide (bis - 3,5,5 - trimethyl hexanoyl peroxide) is used as an initiator in the free radical polymerization of olefinic compounds such as olefines, styrene, vinyl chloride, acrylonitrile and methylacrylate. The peroxide is prepared from 3,5,5-trimethyl hexanoic acid containing less than 0.2% by weight of C8-C10 isomers and/or homologues having at least 5 carbon atoms in a straight chain, any side chains being methyl and/or ethyl groups, for example containing less than 0.1% by weight of 2,4,4-trimethyl pentanoic acid, by known methods. Reference has been directed by the Comptroller to Specification 879,625.
