Thermolysis of silica-immobilized 1-(4(prime)-hydroxyphenyl)-2-phenylethane under D(sub 2). A hydroliquefaction model

摘要

Important conclusions of this study are: Presence of D(sub 2)at 2000 psi does not alter the tendency of surface-attached radicals to rearrange. Hydrocracking is observed for hydropyrolysis of surface-attached materials. Radical D/H exchange is more efficient in the gas phase. Reaction of benzylic radicals with phenols has been documented. Phenoxyl radicals catalyze exchange between D(sub 2) and SiOH groups on silic which in turn promotes exchange at ortho and para ring positions in phenolic compounds.
