Abstract
545,293. Isomeri ation of normal paraffin hydrocarbons. STANDARD OIL DEVELOPMENT CO. May 22, 1940, No. 9068. Convention date, Aug. 12, 1939. Drawings to Specification as open to inspection. [Class 2 (iii)] Normal heptane is catalytically isome ized to isoheptane by contact with aluminium chloride or bromide, the conversion reaction being carried out in the liquid phase at pressure not above atmospheric. The preferred reaction temperature is in the range 25‹-98‹C. If desired there may oe present a promotor such as a hydrogen halide, or an alkyl halide. In examples (1) normal heptane is charged into a distilling flask with aluminium chloride, the flask being fitted with a column packed with carborundum. The reaction temperature remained about 98‹C. (2) A similar run to the above was conducted at a temperature of 33‹C. (3) A similar run to example (1) but at'a temperature of 67‹C., with the addition of about 1 per cent. of water as an activator. The Specification as open to inspection under Sect. 91 describes also the isomerisation of any straight chain paraffins containing at least four carbon atoms, the reaction being carried out in the liquid phase if desired under elevated pressure at temperatures up to 200 ‹C. The invention is described with reference.to butane or a hydrocarbon feedstock containing butane. The drawings disclose a complete isomerization and fractionation plant of the usual type. This subject-matter does not appear in the Specification as accepted.
