Abstract
546,493. Organo mercury compounds. AINLEY, A. D., SHARP, F. L., and IMPERIAL CHEMICAL - INDUSTRIES, Ltd. Jan. 15, 1941, No. 552. [Class 2 (iii)] [Also in Groups VIII and VI] Timber is preserved and seeds and tubers are immunized by treatment with compositions comprising di-(arylmercuri) ammonium salts of the general formula (RHg) 2 NH 2 X where R is a phenyl, tolyl, xylyl or naphthyl radical which may be substituted by halogen, nitro, amino, alkylamino, hydroxy, carboxy or sulpho groups and X is an anionic residue of an acid strong enough to yield a water-soluble product. The salts are obtained by the action of ammonia with or without ammonium or other inorganic salts or arylmercuri salts in aqueous media. Examples describe the treatment of (1) timber with aqueous solutions of di-(phenylmercuri) ammonium salts ; (2) seed potatoes with an aqueous solution of di-(phenylmercuri) ammonium acetate, polyglycerol ricinoleate, sodium acetate, sodium bicarbonate and ammonium sulphate; (3) and (5) oat seeds with a dry mixture of di-(phenylmercuri) ammonium acetate, di-(p-chloro-phenylmercuri) ammonium acetate, di-(m-nitro-phenylmercuri) ammonium chloride, di-m-tolylmercuri) ammonium acetate or di-(α-naphthylmercuri) ammonium acetate, talc and spindle oil.
