α-propyl-γ-butyrolactone (also known as α-MBC) is a common organic solvent. It has a colorless and odorless liquid state and has a low degree of evaporation at room temperature. Here are the details about α-propyl-γ-butyrolactone:
Quality:
- α-propyl-γ-butyrolactone has excellent solubility and can dissolve many organic substances such as resins, paints and coatings.
- This lactone is non-flammable, but it can produce toxic gases at high temperatures.
Use:
- α-Propyl-γ-butyrolactone is widely used in industrial manufacturing processes for solvents, foams, paints, coatings, adhesives, and plastic products.
Method:
- α-propyl-γ-butyrolactone is usually prepared by esterification of γ-butyrolactone. In this process, γ-butyrolactone reacts with acetone and an excess of hydrochloric acid or sulfuric acid is added as a catalyst.
