FAQ

What are the physical and chemical properties of Potassium sulfamate (CAS: 13823-50-2)?

Potassium sulfamate (CAS: 13823-50-2) is a white, crystalline solid. It has a molecular weight of approximately 136.17 g/mol and a solubility of 110 g/100 mL in water. It is slightly soluble in ethanol and practically insoluble in ether. Potassium sulfamate is relatively stable under normal conditions but can react with strong acids to release hydrogen sulfide gas.

How is Potassium sulfamate (CAS: 13823-50-2) typically synthesized?

Potassium sulfamate is typically synthesized by reacting sodium sulfamate with potassium hydroxide. The reaction is conducted in a solution of sodium sulfamate and potassium hydroxide, yielding potassium sulfamate as a precipitate. The reaction is exothermic, and careful temperature control is necessary to ensure product purity.

What industries use Potassium sulfamate (CAS: 13823-50-2)?

Potassium sulfamate (CAS: 13823-50-2) is primarily used in the textile industry for softening fabrics and improving their hand feel. It is also used in the paper industry as a sizing agent and in the chemical industry as a precursor for other sulfur compounds.

What precautions should be taken when handling Potassium sulfamate (CAS: 13823-50-2)?

Precautions when handling Potassium sulfamate (CAS: 13823-50-2) include wearing appropriate personal protective equipment (PPE) such as gloves and safety glasses. Store in a cool, dry place away from heat sources and strong acids. Use a fume hood during handling to avoid inhaling dust or fumes. Consult the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
