What is the origin of ethyl benzene in the polystyrene recycling process, and how is it separated?

Label:chem

Topic
Ethyl benzene is a co-product of polystyrene depolymerization and is also used in the production of polystyrene.
Answer
Ethyl benzene is a co-product formed during polystyrene pyrolysis. It is separated from styrene in the first distillation column as part of the light fraction, which also includes benzene and toluene.
