Potassium hydroxide is a white rhombic crystal, and industrial products are white or light gray block and rod shaped. Relative density 2.044 (20 ℃). Melting point 360.4 ℃. Boiling point 1320~1324 ℃. It is easily soluble in water and emits a large amount of heat when dissolved. It has strong water absorption ability and can absorb water to dissolve in the air, gradually transforming carbon dioxide into potassium carbonate. Soluble in ethanol, slightly soluble in ether. It has extremely strong alkalinity and corrosiveness, and its properties are similar to those of caustic soda. The refined naphthalene manufacturer will explain to you:
