Propylene Oxide
Use. Propylene oxide is an important basic chemical intermediate. Nearly all of the propylene oxide produced is converted into derivatives, often for applications similar to those of ethylene oxide derivatives. Propylene oxide is used primarily to produce polyether polyols, propylene glycols and propylene glycol ethers.
