Potassium hydroxide (chemical formula: KOH, amount: 56.11) white powder or flaky solid. Potassium Humate Melting point of 360 ~ 406 ℃, the boiling point of 1320 ~ 1324 ℃, the relative density of 2.044g / cm3, flash point of 52 ° F, refractive index n20 / D1.421, steam pressure 1mmHg (719 ℃). With strong alkaline and corrosive. Easy to absorb moisture in the air and deliquescence, absorption of carbon dioxide from potassium carbonate. Dissolved in about 0.6 parts of hot water, 0.9 parts of cold water, 3 parts of ethanol and 2.5 parts of glycerol. Potassium Humate When dissolved in water, alcohol or treated with acid to produce a lot of heat. The pH of the 0.1 mol / L solution was 13.5. Medium toxic, half lethal dose (rat, oral) 1230mg / kg. Soluble in ethanol, Potassium Humate slightly soluble in ether. Has a very strong alkaline and corrosive, its nature and caustic soda similar
1, used as a desiccant, absorbent, for the production of oxalic acid and a variety of potassium, but also for electroplating, sculpture, lithography and so on.
2, mainly used for the production of raw materials such as potassium, such as potassium permanganate, potassium carbonate and so on. In the pharmaceutical industry, Potassium Humate for the production of potassium boron, spironolactone, heparanol, testosterone propionate and so on. In the light industry for the production of potassium soap, alkaline batteries, cosmetics (such as cold cream, cream and shampoo). In the dye industry, for the production of dyes, such as reducing blue RSN and so on. In the electrochemical industry, for electroplating, sculpture and so on. In the textile industry, for printing and dyeing, bleaching and mercerizing, Potassium Humate and a large number of used for the manufacture of man-made fibers, polyester fiber main raw materials. In addition, it is also used for metallurgical heaters and leather degreasing and so on.
3, chemical raw materials, for medicine, household chemicals and so on.
4, used as analytical reagents, saponification reagents, carbon dioxide and moisture absorber.
5, the chemical industry for the manufacture of washing soap, Potassium Humate shampoo soft soap, cream, cold cream, shampoo and other raw materials. The pharmaceutical industry for the manufacture of progesterone, vanillin and other raw materials. The dye industry is used to make melamine dyes. The battery industry is used to make alkaline batteries.
Preparation of Electrolyte for Mercury Electrolysis with Diaphragm Electrolysis. Electrolysis chamber to graphite (or metal) for the anode, mercury as the cathode, Potassium Humate electrolysis of chlorine gas to chlorine drying process, the formation of potassium amalgam into the mercury chamber. Most of the unreacted potassium chloride is treated in a dilute brine state and returned to the raw material dissolving step. Potassium amalgam reacts with water to produce potassium hydroxide and hydrogen. Due to the mercury solution out of the potassium hydroxide concentration of 45% to 50%, can be used as liquid potassium hydroxide products, Potassium Humate but also by the caustic soda pot steamed into solid or made of potassium hydroxide products.
