use:
Used as raw material for potassium salt production, such as potassium permanganate, potassium carbonate, etc. In the pharmaceutical industry, it is used to produce potassium borohydride, spironolactone, salbutamol, progesterone and testosterone propionate. In light industry, it is used to produce potassium soap, alkaline storage battery, cosmetics (such as cold cream, vanishing cream and shampoo). In the dye industry, it is used to produce vat dyes, such as vat blue RSN. In the electrochemical industry, it is used for electroplating, engraving, etc. In the textile industry, it is used in printing and dyeing, bleaching and mercerizing, and is used in large quantities as the main raw material for man-made fibers and polyester fibers. In addition, it is also used in metallurgical heating agents and leather degreasing. Used as alkaline agent and coloring agent for cocoa products. Used in the manufacture of compound fertilizers, pharmaceuticals, and electroplating industries. It can be used as a catalyst for the production of polyethers, demulsifiers, detergents, surfactants, etc., and also used in industries such as medicine, dyes, and light industry.
