Construction Chemistry
Potassium Carbonate
Formula:
K₂CO₃
GOST/CAS:
ГОСТ 10690-73
Potassium carbonate (potash) is a highly purified inorganic compound that serves as a key component in chemical synthesis, heavy-duty glass manufacturing, liquid soap production, and as an excipient and buffering agent in the pharmaceutical industry. The product is a white, fine crystalline powder, highly soluble in water, forming a strongly alkaline solution. Due to its unique chemical properties, it is indispensable for dehydration, acid neutralization, and pH regulation in industrial technologies.
Applications
Chemical Synthesis & Pharmaceuticals: Extensively used as a reagent in organic synthesis (for alkylation and acylation reactions), as well as a buffering agent in drug manufacturing and for pH regulation of reaction media.
Glass Industry: A core component in the production of heat-resistant, optical, crystal, and specialized laboratory glassware, providing enhanced clarity, strength, and thermal resistance.
Manufacturing & Consumer Chemicals: Serves as a primary raw material for the production of high-quality liquid green soap, industrial detergents, and as a fixing agent in the textile dyeing industry.
Construction Industry: Utilized as a highly effective anti-freeze admixture (anti-frost additive) for concrete and mortars, enabling construction activities to proceed at sub-zero temperatures (down to -25C).
Key Advantages
High Chemical Purity: Manufactured under strict quality control regarding core substance content and minimal heavy metal levels, ensuring consistent and predictable technological processes.
Excellent Solubility & Reactivity: Dissolves rapidly and completely in water, ensuring immediate neutralization reactions and precise adjustment of the alkaline balance.
Strong Hygroscopic Properties: Acts as an excellent desiccant for drying gases and organic liquids in laboratory and industrial practices by efficiently binding moisture.
Eco-Friendly & Safe to Handle: When standard technological protocols are followed, the product does not emit toxic fumes, is environmentally safe, and can be easily neutralized for disposal.
Storage & Transportation
- Store in a dry, cool, and well-ventilated warehouse in tightly sealed original packaging, separated from acids.
- Protect from direct sunlight and moisture exposure. The product is highly hygroscopic and rapidly absorbs moisture from the air, which leads to caking.
- Transportation is permitted by all types of covered transport vehicles in compliance with standard freight regulations. The product is not classified as hazardous cargo for transport (ADR/RID free).
- Shelf life — 2 years from the date of manufacture, provided the original packaging remains hermetically sealed.
