2methyloxirane

2-Methyloxirane, also known as propylene oxide, is an organic compound with the chemical formula C3H6O. It is a cyclic ether and an epoxide. At room temperature, it is a colorless, volatile liquid with a characteristic ethereal odor. It is highly flammable and miscible with water, ethanol, and ether.

The primary industrial use of 2-methyloxirane is as a chemical intermediate. It is a crucial precursor in the production of polyether polyols, which are then used to manufacture polyurethanes. Polyurethanes find widespread application in foams, coatings, adhesives, and elastomers. Additionally, 2-methyloxirane is employed in the synthesis of propylene glycols, which are used in antifreeze, de-icing fluids, and as a solvent. It also plays a role in the production of detergents, pharmaceuticals, and as a fumigant.

2-Methyloxirane is typically produced industrially through the chlorohydrin process or by direct oxidation of propylene. Due to its reactivity, it can undergo ring-opening reactions with various nucleophiles, forming a range of derivatives. Its volatility and flammability necessitate careful handling and storage. It is classified as a hazardous substance and exposure limits are established to protect workers.
