ABSTRACT:
In the recovery of dehydrogenation oil from the reaction product gas from the vapor-phase catalytic dehydrogenation of diethylbenzene by condensing the gas in a condenser, this invention relates to a process for preparing divinylbenzene by spraying a high-boiling oil or a high-boiling oil and water inside the condenser and letting the oil or the oil and water contact the reaction product gas and the process is capable of dehydrogenating diethylbenzene at high levels of conversion and selectivity without blocking of the condenser and yielding divinylbenzene of high concentration efficiently in a long-term stable continuous operation.
