Editing Styrene (section)

==== From toluene and methanol ====
Styrene can be produced from [[toluene]] and [[methanol]], which are cheaper raw materials than those in the conventional process. This process has suffered from low selectivity associated with the competing decomposition of methanol.<ref>{{cite journal |last1=Yashima |first1=Tatsuaki |last2=Sato |first2=Keiichi |last3=Hayasaka |first3=Tomoki |last4=Hara |first4=Nobuyoshi |year=1972 |title=Alkylation on synthetic zeolites: III.
