Abstract
436,042. Electrodeposition of metals. HARSHAW CHEMICAL CO., Elyria, Ohio, U.S.A. Nov. 3, 1934, Nos. 31654 and 31655. Convention dates, March 14 and May 4. [Class 41] The electrolytes employed are characterized by the addition of a small amount of a preformed sulphuric acid reaction product of a terpenic compound. The terpenic compounds include terpenes, hemi-terpenes, diterpenes, polyterpenes and their derivatives, related resins and oleo-resins and their derivatives. Numerous examples of such compounds are given. Preferred examples of initial substances are a pine tar distillate and a rosin oil, preferably a de-acidified rosin oil; examples of the sulphonation treatment of these substances are given. The acid products may be employed as such or may be neutralized by an alkali or by a compound of the metal to be deposited. The proportion of the addition may be 0À01-12 oz. per U.S.A. gallon. Examples of acid baths for depositing nickel, copper, zinc, cadmium, and a tin alloy containing a small proportion of nickel, and of cyanide baths for copper and cadmium are given.
