WebA system is described for the pyrolysis of deuterated and normal toluene using hydrogen as a carrier gas, which produces a simplification in the results. With hydrogen or deuterium as the carrier gas, the quartz tube furnace remains clean, and the only isolable products of the pyrolysis are benzene and methane in approximately equal amounts. WebToluene is used as a cement for fine polystyrene kits (by dissolving and then fusing surfaces) as it can be applied very precisely by brush and contains none of the bulk of an adhesive. Toluene can be used to break …
