Abstract: 1,174,278. Acetylene. BADISCHE ANILIN- & SODA-FABRIK A.G. 21 April, 1967 [22 April, 1966], No. 18429/67. Heading C5E. Acetylene is produced by incomplete combustion of gaseous or vaporized hydrocarbons (e.g. light naphtha) with oxygen, with subsequent quenching, the reaction being carried out in the presence of CO 2 which is added continuously to the hydrocarbon feed, the oxygen or the mixture thereof prior to the reaction in an amount of 10-50 vol. per cent with reference to the oxygen amount. Carbon black formation is reduced and acetylene yield increased.

Abstract: Acrylonitrile and methacrylonitrile are separated from mixtures, obtained by the ammonia oxidation of propylene or isobutylene, by extractive countercurrent methods wherein the extractive solvent is a 5- or 6-ring membered lactam, N-substituted lactam or lactone, an acyclic or cyclic sulphone or sulphoxide, an N-alkylcarboxylic amide, an N,N-dialkylcarboxylic acmide or propylene carbonate. The two phase flowing in counter current comprise the reaction mixture and the solvent and may be liquid/liquid phases or gas/liquid phases respectively. The process is illustrated by reference to flow drawings (not shown) representing a gas/liquid extraction and extractive distillation. A liquid/liquid extraction using an auxiliary solvent is also described. Examples relate to the use of N-methylpyrrolidone, propylene carbonate, 3 - methyltetramethylene sulphone, butyrolactone, dimethyl sulphoxide, N - q -hydroxyethyl pyrrolidone, and dimethyl-formamide as extractive solvents.
