Compound Q&A
How is Poly(Propylene Glycol) (CAS: 25791-96-2) typically synthesized?
Answer
Poly(Propylene Glycol) (PPG) is synthesized by the polymerization of propylene glycol. This process involves the repeated addition of propylene oxide to propylene glycol in the presence of a catalyst, such as a strong acid or a metal alkoxide. The reaction is typically carried out under anhydrous conditions to ensure high molecular weight and high selectivity, leading to a high yield of PPG.
