氯气(Cl2)在氯碱生产工艺中,由直流电电解饱和食盐水溶液所制取,是重要的化工原料。它用途极广,主要有杀菌消毒、纸浆纤维漂白、矿物氯化法精炼等,用于无机合成方面,如漂白剂(漂白粉、漂白精及次氯酸钠)、三氯化铝、氯化磷、农药、三氯化铁、照相氯化银、氯化钾、合成盐酸、四氯化钛和氯化硅等;用于有机合成
Chlorine (Cl2) in the chlor-alkali production process, made by the DC electrolysis of saturated salt water solution is made, is an important chemical raw materials. Its use is very wide, mainly sterilization, pulp fiber bleaching, mineral chlorination refining, for inorganic synthesis, such as bleach (bleach, bleach and sodium hypochlorite), aluminum chloride, phosphorus chloride, pesticides, Ferric chloride, photographic silver chloride, potassium chloride, synthetic hydrochloric acid, titanium tetrachloride and silicon chloride, etc .; for organic synthesis
