说明

一般描述

Styrene oxide is an oxirane derivative, which is used as a monomer for the synthesis of polyesters with relatively high T_g values via ring-opening copolymerization. It can also be used as a useful intermediate in the preparation of levamisole, a nematocide and anticancer agent.[1][2]

应用

(S)-(-)-Styrene oxide can undergo copolymerization with CO₂ to form the corresponding polycarbonate in the presence of a cobalt-based catalyst system.[3]

注意

Product should be sampled and packaged in a glove bag under nitrogen.
