Description

The conversion of [11C]methanol has been investigated over H/ZSM-5 zeolite between 250-380 deg C for the purpose of [11C]methylation of benzene and toluene. The aim of this work is to obtain details about the mechanism of [11C]methanol-to-[11C]hydrocarbon reaction. Compared to 14C tracer technique, the application of 'no carrier added' radiochemical method precludes the disturbing effect of natural carbon impurities starting from 11C-labeled methanol, and at the same time it was sensitive enough to detect very low amounts of methanol or hydrocarbon products.
