Abstract
Ethyl benzene mixed with benzene is subjected to cracking temperatures, and styrol is separated from the mixture of styrol, benzene, and byeproducts which is produced. One or more substances which favour the dehydrogenation either chemically, by forming stable compounds with the hydrogen which is produced, or physically by reducing the partial pressure of the ethyl benzene, may be present during the reaction. Examples of dehydrogenating substances which act chemically are carbon disulphide, carbon tetrachloride, ethylene, and sulphur; nitrogen, ammonia, carbon dioxide, and volatile organic compounds such as ethyl alcohol or acetone act physically; while ethylene chloride, sulphur monochloride, sulphur dichloride, and sulphur dioxide act both chemically and physically. Suitable mixtures of such substances are sulphur and ethylene chloride or sulphur and acetone. The reaction may be carried out in an iron or chemical tube furnace, which may be heated electrically, and the temperature in the reaction zone may be in the range 600-750 DEG C., and preferably in the range 675-720 DEG C. The products are purified by steam distillation, and the recovered hydrocarbon other than styrol may be returned to the reaction. An example is given.
