ACHIEVING HIGH-PERFORMANCE LOW-COST PROCESSES FOR THE MANUFACTURE OF ORGANIC CHEMICALS USING PHASE TRANSFER CATALYSIS

摘要

Phase Transfer Catalysis, PTC, is widely used in the commercial manufacture of specialty and commodity organic chemicals. PTC can be described as catalytic one-step extraction and reaction of anions. PTC can also be used to simultaneously extract and react anions (or easily ionized organic compounds) from waste streams and convert them into value added products. Such waste streams can include cyanide from mining, mercaptans from petrochemicals and phenol from chemical processes. PTC processes provide many cost and performance benefits, including high yield, short cycle time, flexible choice of solvent, reduced solvent usage, lower excess of reactants, use of alternate less expensive raw materials and a variety of safety and environmental benefits.
