Abstract

324,774. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Dec. 21, 1928. Chlorinated naphthalene compounds.- Wax-like chlorinated compounds of naphthalene, with a chlorine content of below 60 per cent, are obtained by effecting the chlorination of melted naphthalene with elementary chlorine at a temperature below 130‹ C. in the presence of a catalyst, such as antimony, phosphorus, sulphur, iodine or a compound thereof. Air may then be forced through the belt for some time, after which it can be used directly or distilled under reduced pressure. Specifications 291,849 and 292,056 are referred to.
