As a metallurgical flux The use of zinc chloride as a flux, sometimes in a mixture with ammonium chloride (see also Zinc ammonium chloride), involves the production of HCl and its subsequent reaction with surface oxides. Zinc chloride reacts with metal oxides (MO) to give derivatives of the idealized formula MZnOCl2. … Ver mais Zinc chloride is the name of inorganic chemical compounds with the formula ZnCl2 and its hydrates. Zinc chlorides, of which nine crystalline forms are known, are colorless or white, and are highly soluble in water. … Ver mais Anhydrous ZnCl2 can be prepared from zinc and hydrogen chloride: Zn + 2 HCl → ZnCl2 + H2 Hydrated forms and … Ver mais Zinc chloride is used as a catalyst or reagent in diverse reactions conducted on an industrial scale. The partial hydrolysis of benzal chloride in the presence of zinc chloride is the main route to benzoyl chloride. It serves as a catalyst for the production of … Ver mais • N. N. Greenwood, A.
