Catalytic Processes in Materials Science

The hydrocracking of phenanthrene, anthracene, pyrene, chrysene, and fluoranthene over molten salt catalysts at 400 °C in the batch autoclave systems was examined. The products were mainly identified by means of GC-MS, but the representative products were isolated by preparative GLC and characterized by using NMR, IR, UV, and mass spectrometry. Most of the isolated products are compounds not previously confirmed in detail, although their formation has been expected in the hydrocracking of the corresponding aromatic compounds. Probable reaction routes are offered based on the product distributions. The binary mixture of zinc chloride and copper(I) chloride is considered to act as a molten dual-functional catalyst.
