Abstract
Residual products obtained in the catalytic dehydration of alpha-methylbenzyl alcohol are treated to recover increased quantities of ethylbenzene by a process which comprises thermally cracking the residual products in the substantial absence of hydrogen under elevated pressures.
Claims7
A process for the recovery of aromatic hydrocarbons from dehydration residues obtained in the preparation of styrene from alpha-methylbenzyl alcohol which comprises thermally cracking the residues at a temperature within the range from about 325.degree. C.-475.degree. C. and a pressure within the range from about 75 to 300 psig, withdrawing the cracked effluent and recovering liquid aromatic hydrocarbons.
