Abstract
A process for making styrene by the cracking of beta-phenethyl acetate wherein the beta-phenethyl acetate is derived from the esterification of beta-phenethyl alcohol. The latter is derived from the homologation of benzyl alcohol-benzyl acetate mixtures. The esterification of the beta-phenethyl alcohol may be partial because it has been found that up to 20% by weight of beta-phenethyl alcohol may be fed to the cracking step and also converted to styrene. Benzyl alcohol and benzyl acetate can also be fed to the cracking step because it has been found that they are essentially inert at cracking conditions.
