Abstract: 1,054,011. Tetrachloroxylene derivatives. ALLIED CHEMICAL CORPORATION. Feb 26, 1965 [Feb. 27, 1964; March 24, 1964], No 8432/65. Heading C2C. [Also in Division C3] The invention comprises compounds in which a 2,3,5,6-tetrachloro-p-xylene nucleus is linked (a) to two aryloxy radicals of the formula in which R denotes hydrogen or an alkyl group of 1-5 carbon atoms, or (b) to two oxyaryl or etherified oxyaryl radicals. Compounds of type (a) are obtainable by reacting α,α 1 ,2,3,5,6-hexachloro-p-xylene with an appropriate alkalimetal phenate, and examples are given in which the hexachloro compound is reacted with sodium phenolate and o-cresolate. Compounds of type (b) are obtainable by reacting α,α 1 ,2,3,5,6-hexachloro-p-xylene with a phenol or a naphthol, and an example is given in which the hexachloro compound is reacted with α-naphthol. Examples are given also in which α,α 1 -bis-(3,5- dimethyl - 4 - hydroxyphenyl) - 2,3,5,6 - tetrachloro-p-xylene is etherified by reaction with epichlorohydrin, allyl chloride and benzyl chloride. The products are useful as stabilizers for chlorinated polyethylene compositions (see Division C3).
