⚗️ Chemical & Physical Properties
Thioacetic acid is a colorless liquid with a strong odor similar to that of garlic or rotten eggs. It has a pungent smell that is easily detected even in small quantities.
Thioacetic acid has a molar mass of 76.09 g/mol and a density of 1.04 g/cm³. Compared to common household items, it has a lower molar mass than sugar (180.16 g/mol) and a higher density than water (1 g/cm³).
The melting point of thioacetic acid is -22°C, while its boiling point is 80°C. In comparison, water has a melting point of 0°C and a boiling point of 100°C. This makes thioacetic acid a more volatile compound than water.
Thioacetic acid is slightly soluble in water and has a low viscosity. It is more soluble than oil, but less soluble than salt. In terms of viscosity, it is less viscous than honey but more viscous than water.
🏭 Production & Procurement
Thioacetic acid, also known as ethanethioic acid, is primarily produced by the reaction between acetyl chloride and hydrogen sulfide. This reaction, which occurs under controlled conditions, yields thioacetic acid along with hydrogen chloride gas as a byproduct. The resultant thioacetic acid is then purified through distillation to remove impurities and obtain a high-quality product.
Thioacetic acid can be procured commercially from chemical suppliers or manufacturers. It is typically available in liquid form, either in bulk quantities or in smaller volumes for laboratory use. The acid is often transported in sealed containers to prevent leakage and ensure safety during handling and transit. Proper precautions should be taken to avoid direct contact with skin or inhalation of fumes when working with thioacetic acid.
In addition to commercial procurement, thioacetic acid can also be synthesized in laboratory settings by skilled chemists. This involves following established procedures for the reaction between acetyl chloride and hydrogen sulfide, as well as handling and purifying the resulting product. Careful attention to safety measures and proper equipment is essential to successfully produce and handle thioacetic acid in a laboratory environment.
⚠️ Safety Considerations
