| Potassium Hydroxide Other name: Caustic potash Chemical formula:KOH CAS No：1310-58-3 EINECS.No:215-181-3 Molecular weight:56.1056 H ▪ S CODE: 2815200000 UN.No：1813 Properties: Appearance is white flakes solid, KOH is an inorganic compound, is a common inorganic alkali, with strong alkaline, 0.1 mol/L solution pH 13.5, soluble in water, ethanol, slightly soluble in ether, very easy to absorb moisture in the air and deliquescence, absorb carbon dioxide into potassium carbonate Application：1.Used in electroplating, engraving, lithography, etc. 2.Used as raw material for the production of potassium salts, such as potassium permanganate, potassium carbonate, etc. |
3.In the light industry for the production of potassium soap, alkaline batteries, cosmetics.
4.In the pigment industry, it is used for the production of reduction dyes, such as reduction blue RSN, etc.
5.Used as an analytical reagent, saponification reagent, carbon dioxide and moisture absorber.
6.In the textile industry, it is used for printing, dyeing, bleaching and mercerising, and is used in large quantities as the main raw material for the manufacture of
man-made fibres, polyester fibres and also for the manufacture of melaminedyes.
7.It is used as a metallurgical heating agent and in the degreasing of leather.
