Potassium the hydroxide represents white scales, granules of lenticular form or pieces with crystal structure on break; it is strongly hygroscopic, well soluble in water and alcohol; quickly absorbs carbonic acid and water from air and gradually passes into potash.
Potassium hydroxide is applied to production of fertilizers, synthetic rubber, plastic, electrolytes for accumulators, reactants, xanthogenates, for lixiviation of castings of steel molding, for maintenance in the set limits of alkalinity of boring solutions, in production of biodiesel fuel as the catalyst, used in pharmaceutical industry and other industries of national economy.
Potassium hydroxide is stored in hermetically closed container since it "spreads" on air, absorbing from it moisture.
During the work with Potassium hydroxide it is necessary to observe precautionary measures. Its traditional name "caustic heat" reflects the corroding effect of this substance on living tissues. At hit of potassium hydroxide on skin chemical burns are possible.
Potassium hydroxide - the strong basis, enters rough reactions with acids, metals like zinc, tin, lead and aluminum with hydrogen release. Very much pyretic, belongs to the 2nd class of danger. Leads to ozhega at hit on surface of skin of the person and others organic connection. Demands strogov of observance of the accident prevention during the work. Despite it, potassium hydroxide is applied in the food industry as E525 additive. Potassium hydroxide is widely applied by production of liquid soap, receiving different salts of potassium. Also it is applied by production of methane, the defluorinated zirconium hydroxide, and also as electrolyte by production of alkaline batteries. All this provides great demand on this product in the Russian market at wide range of consumers.
