Potassium hydroxide is a strong alkali with extremely strong alkalinity and corrosiveness. It is an important basic chemical raw material and is widely used in the following fields: potassium salt production (core raw material for producing various potassium salts such as potassium permanganate, potassium carbonate, and potassium dihydrogen phosphate), daily chemical industry (production of potassium soap, soft soap, liquid soap, cosmetics (cold cream, snow cream, shampoo), battery industry (manufacturing alkaline batteries), pharmaceutical industry (synthesis of pharmaceutical intermediates, production of potassium borohydride, spironolactone, sha gan alcohol, progesterone), dye industry (production of reducing dyes (such as reducing blue RSN)), textile industry (printing and dyeing, bleaching, and silk processing; main raw materials for manufacturing artificial fibers and polyester fibers), petroleum refining. Water treatment pH adjustment, food industry (food additives (E525) Cocoa coloring agent, rubber (plastic synthetic rubber, ABS resin), electrochemical industry (electroplating, carving, lithography), other/others metallurgical heating agents, leather degreasing, carbon dioxide and moisture absorbing agents, analytical reagents.
