TRANSITIONAL ALUMINA CATALYSTS PROMOTED WITH A LEWIS ACID AND RENTAL PROCEDURES FOR ISOPARAPHINS USED BY THESE CATALYSTS.

摘要

THIS INVENTION REFERS TO: A) A CATALYST SYSTEM, B) A COMPONENT OF THAT SYSTEM THAT INCLUDES CERTAIN TRANSITIONAL ALUMINUMS PROMOTED WITH A LEWIS ACID (PREFERABLY BF3), AND C) A CATALYTIC PROCESS FOR THE RENTAL OF ISOPARA THE CATALYST COMPONENT IS PRODUCED BY CONTACTING THE TRANSITIONAL ALUMINA WITH THE LEWIS ACID AT A RELATIVELY LOW TEMPERATURE OR AT A TEMPERATURE AT WHICH CERTAIN PEAKS OF CHARACTERISTICS APPEAR IN THE NUCLEAR MAGNETIC RESONANCE SPECTRUM (COMPONENTS) THE CATALYST SYSTEM INCLUDES THIS COMPONENT AND AN ADDITIONAL AMOUNT OF FREE LEWIS ACID. THE PROCESS INCLUDES THE RENTAL OF OLEPHINE / ISOPARAPHINE USING THE CATALYST COMPONENT AND ITS ASSOCIATED CATALYST SYSTEM.
