What is potassium hydroxide used for? What is potassium oxide?

Potassium hydroxide. Chemical formula: KOH), commonly known as caustic potassium, white solid, soluble in water, alcohol, but insoluble in ether. It is easy to absorb moisture and deliquescent in the air. Can be used with carbon dioxide.

The reaction produces potassium carbonate. So it will be used to absorb carbon dioxide.

Potassium hydroxide is a typical strong base and has many industrial applications, most of which are due to the fact that potassium hydroxide can react with acids and the corrosive nature of potassium hydroxide itself.

An estimated 700,000 to 800,000 tonnes of potassium hydroxide were produced in 2005, which is about sodium hydroxide.

of one hundredth. Potassium hydroxide is commonly used to make soft and liquid soaps, and is also used to prepare potassium-containing chemicals.

Alkali hydroxide is a strong alkaline substance with its high corrosiveness. Potassium hydroxide can be taken in the laboratory by clamping it with tweezers. Potassium is a very reactive metallic element that reacts easily with water.

Moreover, potassium hydroxide is easy to absorb water in the air and deliquescent. The potassium hydroxide used in industry is a white block or rod. Potassium hydroxide can undergo many chemical reactions, so many chemicals can be obtained by using the chemical reactions that occur with potassium hydroxide, and potassium hydroxide is very useful in industry.

It can be used in a wide range of fields.

The use of potassium hydroxide can be used as an analytical reagent, saponification reagent, absorbent of carbon dioxide and water.

2.It is used for electroplating, engraving and lithographing.

3.In the pharmaceutical industry, it is used for the production of potassium, boron, hydrogen, sotto, sapatine, hepatine, progesterone, vanillin.

4.It is used as a raw material for the production of potash.

5.In the dye industry, it is used to produce vat dyes, etc.

However, potassium hydroxide storage should be stored in a cool, dry and well-ventilated warehouse, and must be kept away from the fire heat source to prevent the humidity in the warehouse from being more than 85%. The packaging must be sealed, should not be damp, should be stored separately from flammable materials and acids, and should not be mixed. Put**.

Uses of potassium hydroxide: 1. Used as analytical reagents, saponification reagents, absorbents for carbon dioxide and water. 2. Used for electroplating, engraving, lithographing, etc.

3. In the pharmaceutical industry, it is used to produce potassium boron hydrogen, spironolactone, sand liver alcohol, progesterone, vanillin, etc. 4. It is used as a raw material for the production of potash. 5. In the dye industry, it is used to produce vat dyes.

K2O is difficult to produce, though, because potassium is oxidized directly into potassium peroxide in the air.

Potassium oxide has a molecular formula of K2O and is a colorless cubic crystal. Density, 350 decomposition, easy deliquescent, soluble in water and combined with hydration to form potassium hydroxide. Mainly used in the inorganic industry, it is the basic raw material for the manufacture of various potassium salts such as potassium hydroxide, potassium sulfate, potassium nitrate, potassium chlorate, potassium alum, etc.

Physicochemical properties. Potassium oxide is a white powder that is dissolved in water to form potassium hydroxide and emits a large amount of heat. When heated in the air stream, it can be oxidized into potassium peroxide or potassium superoxide, and it is easy to absorb carbon dioxide in the air to become potassium carbonate. Reacting with acids can produce the corresponding potassium salts.

Potassium oxide is chemically similar to sodium oxide but is not easily oxidized in air. 350 to K2O2[2].

Solubility: 1g soluble in water, boiling water, 14ml glycerol, about 250ml of ethanol, insoluble in ether, acetone and hydrochloric acid, magnesium chloride, sodium chloride can reduce its solubility in water.

Main uses: Mainly used in the inorganic industry, it is the basic raw material for the manufacture of various potassium salts such as potassium hydroxide, potassium sulfate, potassium nitrate, potassium chlorate, potassium alum, etc.

It is used in the pharmaceutical industry as a diuretic and a drug for the prevention and treatment of potassium deficiency.

The dye industry is used in the production of g-salts, reactive dyes, etc.

It is used in the daily chemical industry to make process soap.

The battery industry uses electrolytes to make alkaline batteries.

In addition, it is used in the manufacture of flame suppressants for muzzles or muzzles, heat treatment agents for steel, and for photography.

Effects: Hypokalemia caused by various causes, such as insufficient feeding, vomiting, severe diarrhea, use of potassium-wasting diuretics, hypokalemic familial periodic paralysis, hypokalemia caused by long-term use of glucocorticoids and hypertonic glucose supplementation, etc.

Efficacy: Prevention of hypokalemia, when patients have potassium loss, especially if hypokalemia occurs and is more harmful to the patient (such as patients using digitalis drugs), prophylactic potassium supplementation is required, such as little food, severe or chronic diarrhea, long-term use of adrenocorticosteroids, potassium-depleting nephropathy, Bartter syndrome, etc.

The role and efficacy of potassium oxide chain shirt fertilizer 1, potassium oxide can make the soil maintain high potassium fertility, it is the basis of high yield and stable yield of crops, and the demand for potassium of crops is more than that of nitrogen and phosphate fertilizer. Most of the potassium absorbed by crops comes from the soil and the application of potassium fertilizers. 2. Potassium oxide can enhance the stress resistance of crops, and potassium application can make crops grow robustly, because potassium ** is sufficient for the root development of plants, which is conducive to the absorption of water by plants from the soil.

Potassium also increases the osmotic pressure of the cell fluid, maintains the elasticity of the cell wall, and reduces the loss of water. 3. Potassium oxide can also improve the quality of crops, because potassium can promote photosynthesis, improve photosynthetic efficiency, and promote the transport of photosynthetic products. When potassium is sufficient, it can not only promote the synthesis of Yodoga powder, but also promote the absorption and utilization of nitrogen by crops, so that protein can be synthesized.

Potassium hydroxide is a common inorganic base with a chemical formula of KOH and a molecular weight, and is a white powder or flake solid at room temperature. The properties are similar to sodium hydroxide, with strong alkaline and corrosive, and the pH of mol l solution is. It is very easy to absorb moisture in the air and deliquescent, absorbing carbon dioxide to form potassium carbonate.

Soluble in about hot water, cold water, 3 parts of ethanol, part glycerol, slightly soluble in ether. When dissolved in water, alcohol, or treated with acids, a large amount of heat is generated. Moderate toxicity, half lethal dose (rat, oral) 1230 mg kg.

The Chinese name is potassium hydroxide.

Foreign name potassium hydroxide is also known as caustic potassium, caustic alkali, and potassium ash.

Potassium hydroxide is used as a raw material for chemical production, and is also used in medicine, dyes, light industry and other industries, agents, absorbents, for the production of oxalic acid and various potassium salts, in dyes, for the production of vat dyes, such as vat green RNS can also be used for metallurgical heating agents and leather degreasing.

The inorganic industry is used as a raw material for the production of potassium salts, such as potassium permanganate, potassium nitrite, dipotassium phosphate, etc. It is used in the daily chemical industry as a raw material for the manufacture of potassium soap, dirt soap, shampoo soft soap, alabaster, cold cream, shampoo, etc. It is used in the pharmaceutical industry to make raw materials such as progesterone and vanillin.

The dye industry is used to make melamine dyes. The battery industry is used to make alkaline batteries. It is used as a desiccant and absorbent, for the preparation of potassium soap, oxalic acid and various potassium salts, and is also used for electroplating, engraving, lithographing, etc.
