1.What is Potassium Chloride?
The chemical compound potassium chloride (KCl) is a metal halide salt composed of potassium and chlorine. In its pure state, it is odorless and has a white or colorless vitreous crystal appearance, with a crystal structure that cleaves easily in three directions. Potassium chloride crystals are face-centered cubic. Potassium chloride was historically known as "muriate of potash". This name is occasionally still encountered in association with its use as a fertilizer. Potash varies in color from pink or red to white depending on the mining and recovery process used. White potash, sometimes referred to as soluble potash, is usually higher in analysis and is used primarily for making liquid starter fertilizers. KCl is used in medicine, scientific applications, and food processing. It occurs naturally as the mineral sylvite and in combination with sodium chloride as sylvinite.
2.How is Potassium Chloride produced?
1. by recrystallization method, industrial potassium chloride is added into the dissolving tank containing distilled water for dissolution, and then decolorant, arsenic remover and heavy metal remover are added for solution purification, after precipitation, filtration, cooling and crystallization, solid-liquid separation and drying, finished product of edible potassium chloride is produced. 2. Take magnesium chloride and potassium chloride as the main components of rock salt carnallite (carnolite) crushed, mixed with 75% of water, passed into the superheated steam, precipitated potassium chloride after cooling. This crude crystal is washed with water and refined by recrystallization. The mother liquor after precipitating sodium chloride from seawater is concentrated, crystallized and refined.
3.How is Potassium Chloride stored and distributed?
Store in a cool, ventilated warehouse. Keep away from fire and heat source. Store separately from oxidizers, do not mix. Suitable materials should be available in the storage area to contain spills. Safety Risks Confined operation, strengthen ventilation. Operators must be specially trained and strictly follow the operating procedures. Operators are advised to wear self-priming filtering dust masks, chemical safety glasses, anti-poison penetration overalls and rubber gloves. Avoid generating dust. Avoid contact with oxidizing agents. Load and unload lightly when handling to prevent damage to packaging and containers. Equip with emergency response equipment for leakage. Emptied containers may retain hazardous materials.
4.What is Potassium Chloride used for?
Mainly used in inorganic industry, it is the basic raw material for the manufacture of various potassium salts or bases, such as potassium hydroxide, potassium sulphate, potassium nitrate, potassium chlorate, potassium alum and so on. It is used as diuretics and drugs to prevent and control potassium deficiency in the pharmaceutical industry. In the dye industry, it is used in the production of G salt and reactive dyes. In agriculture, it is a kind of potassium fertilizer. Its fertilizer effect is fast, directly applied to the farmland, can make the lower soil moisture rise, there is a drought effect. However, it is not suitable for application in saline land and to crops such as tobacco, sweet potato and sugar beet. Potassium chloride is similar in taste to sodium chloride (bitter) and is also used as a low-sodium salt or mineral water additive. It is also used as a deflagrant in the manufacture of muzzles of guns or cannons, as a heat-treating agent for steel, and for photographic purposes. It is also used in medicine, scientific applications, food processing, and in table salt where sodium chloride can be partially replaced by potassium chloride to reduce the possibility of high blood pressure.
