Vinyltoluene monomer

Vinyltoluene (VT) is a mixture of meta- and i ra-vinyltoluenes, typically in the ratio of 60 40. This isomer ratio results from the ratio of the corresponding ethyltoluenes in thermodynamic equiHbrium. Physical properties and chemical analysis of a typical vinyltoluene product are shown in Tables 7 and 8, respectively. Vinyltoluene monomer is produced by Dow Chemical Company and Fina Oil Chemical Company. The worldwide consumption is estimated to be approximately 100,000 t/yr. [Pg.488]

The dehydrogenation of the mixture of m- and -ethyltoluenes is similar to that of ethylbenzene, but more dilution steam is required to prevent rapid coking on the catalyst. The recovery and purification of vinyltoluene monomer is considerably more difficult than for styrene owing to the high boiling point and high rate of thermal polymerization of the former and the complexity of the reactor effluent, which contains a large number of by-products. Pressures as low as 2.7 kPa (20 mm Hg) are used to keep distillation temperatures low even in the presence of polymerization inhibitor. The finished vinyltoluene monomer typically has an assay of 99.6%. [Pg.489]
