Propylene Oxide Manufacture

Propylene oxide (PO) is a highly reactive commodity compound that serves as a starting material for several widely used products, from polymers and solvents to industrial fluids. Historically, PO has been produced by the so-called chlorohydrin process, which is further described in this article. Currently, new production technologies that generate less waste are starting to replace the chlorohydrin production process.

Technology Description

The following paragraphs describe describe a typical chlorohydrin process for PO production from propylene and chlorine. The figure below presents a simplified flow diagram of the process.
