Styrene Production and Manufacturing Process | ICIS

 · In this process, EB is oxidised to its hydroperoxide, which is next reacted with propylene to produce propylene oxide and methyl benzyl alcohol. The latter product is then dehydrated to styrene. The popularity of the PO/SM route with PO producers, compared to the conventional chlorohydrin process, has been put down to better process economics and environmental perspectives.

styrene: styrene-butadiene rubber production process

The flow diagram traces the emulsion process for manufacturing styrene-butadiene rubber. Fresh butadiene and styrene are received, stored, and blended with recovered butadiene and styrene. The two chemicals, along with a catalyst and soap solution, are pumped to the reactors where polymerization takes place. After the short-stop stage, in which an agent is added to the mixture in order to stop ...
