Abstract

1,209,500. Stabilization of polyphenyl thioethers. MONSANTO CO. 18 Oct., 1968, No. 49483/68. Heading C2C. [Also in Division C5] The oxidative stability of a polyphenyl thioether, in which one or more of the sulphur atoms may be replaced by oxygen atoms providing there is at least one sulphur atom in the molecule, is improved by treating the polyphenyl thioether with a metal of Group I B or II B of the Periodic Table or with an oxide of a said metal. In addition, treatment with alumina may be effected, if desired, either before or after the treatment with said metal or metal oxide. The process is suitable for the treatment of polyphenyl thioethers of the formula where m is an integer from 0 to 6, or of the formula where A and A<SP>1</SP> may each represent oxygen or sulphur, or of the formula wher x and y are integers from 0 to 3 and x+y is from 1 to 6 and A and A<SP>1</SP> may each represent oxygen or sulphur but at least one of A and A<SP>1</SP> is sulphur, or of the formula where R 1 -R 4 each represent a hydrogen or halogen atom or an alkyl C 1-4 , alkoxy C 1-4 ; haloalkyl C 1-4 , e.g. trifluoromethyl, perfluorobutyl, aryl, aryloxy, alkaryl, phenylmercapto, hydroxyl or haloaryl radical, A, A<SP>1</SP> and A<SP>11</SP> are each selected from oxygen and sulphur, provided that at least one of A, A<SP>1</SP> and A<SP>11</SP> is sulphur, m and n are integers from 0 to 3 provided m + n is at least 1, p is an integer from 1 to 3 and o is an integer from 0 to 1 providing at least one o is 1, or mixtures thereof. In examples, m-bis- (phenylmercapto)benzene and a mixture of bisphenoxyphenyl sulphide, bis-(m-phenylmercaptophenyl) sulphide and m-phenoxyphenyl mphenylmercaptophenyl sulphide are treated with various metals and metal oxides according to the invention. The thus-treated polyphenyl thioethers are stated to be less corrosive towards silver and copper.
