Abstract

535,435. Isomerization of chlor-alkanes. FIFE, J. G. (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij. Nov. 27, 1939, No. 30873. [Class 2 (iii)] Mono- or poly-chlor-alkanes containing less than 10 carbon atoms in the molecule are isomerized by treatment with acid acting metal, halides or boron halides, at temperatures below 200‹ C. The halides preferred are aluminium chloride, double compounds thereof such as Gustavson compounds or boron fluoride. The reaction may take place in the presence of activating compounds such as hydrogen halides. These compounds also check the decomposition of the chlor-alkanes. The catalysts may be used in combination with carrier materials such as active charcoal, silica gel, pumice, kaolin, and activated aluminium oxide. The reaction may take place in the gaseous or the liquid phase and under normal, raised or reduced pressure. The effect of the isomerization process of the present invention in the case of dichlor alkanes is to space further apart the chlorine atoms in the molecules and in the case of monochlor alkanes to shift the chlorine atom from one carbon atom to another. In an example, 1:2-dichlorbutane is treated with aluminium chloride in a U 2 A steel autoclave in the presence of hydrogen chloride at 10 atmospheres pressure at 30‹ C. The dichlor alkanes produced by the process of the invention may be used as initial materials for the production of dicarboxylic acids used in synthetic resin preparation.
