propyleenioksidi

Propyleenioksidi, also known as metyylioksiraani, is an organic compound with the chemical formula C3H6O. It is a colorless, volatile liquid with a distinct ether-like odor. Propyleenioksidi is a cyclic ether and an epoxide, meaning it contains a three-membered ring consisting of two carbon atoms and one oxygen atom. This ring structure makes it a highly reactive compound.

Industrially, propyleenioksidi is a crucial intermediate in the production of various chemicals. Its primary application is in the synthesis of polyether polyols, which are essential components in the manufacture of polyurethane foams. These foams are widely used in furniture, bedding, automotive parts, and insulation. Propyleenioksidi is also used to produce propylene glycol, a humectant found in cosmetics, food, and pharmaceuticals, as well as in antifreeze solutions. Other derivatives include glycol ethers, which serve as solvents and surface-active agents.

The production of propyleenioksidi typically involves the epoxidation of propylene. Common methods include the chlorohydrin process and direct oxidation processes, such as the hydroperoxide methods. Due to its reactivity and flammability, propyleenioksidi requires careful handling and storage. It is classified as a hazardous substance and can cause irritation to the skin, eyes, and respiratory system.
