摘要：
The Organic Phosphorus Compounds (OPCs) a - d have been thermolyzed using a plug flow (gas-phase) reactor. Compounds a and b proved to be sensitive to acid (wall) catalysis and can be fully degraded at T much less than 400-degrees-C. Likewise d can isomerise into a and b. In contrast, c requires T > 750-degrees-C for complete conversion; admixed with a it counteracts the smooth acid mediated degradation of a. Unlike 'real' thermolysis at elevated T - preferably in a reducing atmosphere of hydrogen -, mere acid catalysis is not generally applicable to effectively destroy a variety of - ecotoxic - OPCs.
