Title:
METHOD AND REACTOR FOR THERMAL AFTER-TREATMENT OF CRACKED PRODUCT FROM ACID CATALYTIC CRACKING OF CUMENE HYDROPEROXIDE
Document Type and Number:
Japanese Patent JP2002003417
Kind Code:
A
Abstract:
To provide the subject method excellent in high selectivity and high usability as well owing to both low energy cost and reduced deposits.
This method comprises making a thermal after-treatment of the cracked products from acid catalytic cracking of cumene hydroperoxide into phenol and acetone by heating the cracked products in a reactor; wherein it is characterized to make use of at least the heat of reaction in an exothermic reaction proceeding in the reactor in order to heating the cracked products.
