Read the description of potassium carbonate in textiles in this article.Potassium carbonate (K2CO3) is a white solid salt, miscible in water and not miscible in ethanol, and forms an alkaline solution. It can be prepared by reacting the adsorbent of potassium hydroxide with carbon dioxide.Also known as potash, it may be used in pharmaceutical laboratories as a desiccant or as a source of potassium. It is also used in fire extinguishers, soap making, glass making, as well as in large quantities to eliminate water hardness. It is also present in multivitamin tablets.In health agencies and organizations, carbonated salts are grouped as safe chemicals. It is also used in the pottery industry because it is an excellent chemical for glazing pots. Potash is also widely used as a flux in the metal industry. It is also used in the textile industry.
A liquid alkaline compound is used to dye the fibers of cotton composite fabrics or similar items. This soluble liquid alkali can be sodium hydroxide, potassium hydroxide and potassium carbonate, which is formed by the reaction of CO 2 and is obtained by mixing with potassium hydroxide solution and adding sodium hydroxide.The resulting supersaturated solution has sufficient total alkalinity to achieve the reaction between the dyes, including vinyl sulfonate and fiber paints, but is buffered sufficiently to achieve this reaction smoothly and the reactive dyes of the fiber as a uniform, uniform surface. To be.Potash is used as a bleach in the textile industry. It is also widely used for washing and dyeing wool.This material is used for dyeing and washing leather products.Potassium carbonate is used as a reducing agent in printing paste. Printing paste usually contains materials that reduce the color or absorb the reduced composition by suitable textile fibers.
Potassium carbonate is the main component of potash and is derived primarily from the salt extracted from potash. The old method was to collect or produce wood ash. Currently, this material is mainly produced by the following three processes.Obtaining potassium hydroxide first by electrolysis of potassium chloride and then reaction with carbon dioxide this is a Applications of Potassium carbonate.
Chlorine (Cl2) and hydrogen (H2) are by-products. This is the most widely used commercial method as well as the method of producing potassium hydroxide. The following is the chemical equation for this process:
2 KCl + 2 H2O → 2 KOH + H2 + Cl2
2 KOH + CO2 → K2CO3 + H2O
Treatment of potassium hydroxide solution with excess carbon dioxide.
2KOH + 2CO2 = K2CO3
Carbon dioxide gas is transferred to the potassium hydroxide solution to first produce potassium bicarbonate and then heat it.
KOH + 2CO2 + H2O = 2KHCO3 2KHCO3 = K2CO3 + CO2 + H2O
The above three methods are mainly used to produce heavy potassium carbonate, which has a higher density than its light type. The second method can be produced by ion exchange method:
(NH4) 2CO3 + KCl
Potassium carbonate hydrate is formed from the above solution after crystallization and drying, which can be heated to more than 200 ° C to obtain anhydrous potassium carbonate.Potassium carbonate is one of the most widely used chemical compounds that has many useful properties. This chemical compound in both soluble and dry forms can irritate the skin, eyes and respiratory system. It is important to use this chemical compound with caution. It is available in many forms in many online stores. It is available in crystalline and powder form with different price rates.
Potassium carbonate is not compatible with oxidants, acids, alkali metals, nitrates, chlorine, aluminum, fluorine, magnesium, silicon, chlorine trichloride.
