Catalyst for α- Phenethyl Alcohol to Styrene


1.Main Functions

We use co-generation of styrene and propylene oxide (PO/SM) method to produce styrene. In this route, ethylbenzene is reacted with the air to generate ethylbenzene hydroperoxide, then react with propylene to produce propylene oxide and α-phenethyl alcohol, then catalytic dehydrated to the styrene. The reaction by-product, acetone, is hydrogenated to produce the α-phenethyl alcohol and then circulates back to the dehydration system.

Gamma alumina is used as catalyst for dehydration production of α-phenethyl alcohol to styrene. The catalyst made by our company has two advantages: (i) high activity and high  stability; (ii) steady running 2000 hours or more under laboratory conditions, and comprehensive product selectivity of 99% or higher.
