Oxidative Coupling of'By-Product Coke Phenols as a Way of Their Utilization as Thermal Polymerization Coinhibitors in Styrene Distillation

摘要

A procedure was suggested for chemical modification of by-product coke phenols for their use as polymerization inhibitors in petrochemical production of vinyl monomers.The optimal ratios and amounts of components of the inhibiting formulation,Mannich base and modified by-product coke phenols,in heat treatment of styrene were determined.
