Title: Process for the production of rubber-like polymers
IPC: C08F210/12
Filed: 1944-11-17
Abstract: In the low temperature polymerization of iso-olefines having up to 8 carbon atoms with or without a minor proportion of a diolefine having up to 14 carbon atoms, in an alkyl halide diluent having less than 5 carbon atoms at temperatures below -40 DEG  C. in the presence of a Friedel-Crafts catalyst dissolved in the same alkyl halide, the reaction slurry is passed into warm water in a flasking zone and its volatile components vaporized and withdrawn, cooled, compressed and dried.  The volatile components are then fractionated to give substantially pure alkyl halide (which is used for the preparation of catalyst solution), a mixture of iso-olefine and alkyl halide which is recycled to the feed, and a residue of hydrocarbon by-products which is discarded.  The residue may be further fractionated to separate any unreacted diolefine present which is recycled to the feed.  Where the alkyl halide is very volatile, e.g. methyl chloride, the pure halide is withdrawn in a first distillation and the mixture of alkyl halide and iso-olefine distilled from the residue, but where a less volatile halide is used, e.g. ethyl chloride, the mixture is removed first and pure alkyl halide distilled from the residue. The alkyl halide recovered may be purified by scrubbing with sulphuric acid, passed over dry caustic soda and redistilled before using to prepare catalyst solution.  Isobutylene is the preferred iso-olefine and diolefines specified include butadiene, isoprene, dimethyl butadiene, piperylene, myrcene and dimethylallene.  Isobutylene for the feed may be distilled twice, first to remove water and again to remove isobutane, normal butylenes and C5 and heavier hydrocarbons. The diolefine used may be first purified by washing with water and distilled after addition of inhibitor, e.g. tert-butyl catechol or hydroquinone.  Specifications 432,196, 483,453, 561,324 and 565,974 are referred to.

Title: A process for preparing a substituted or unsubstituted tropolone
IPC: C07C35/20
Filed: 1962-06-18
Abstract: Tropolones are produced by replacing with hydroxyl a halogen atom in halogenotropones. The hydroxyl group in the product may be in the 2-, 3- or 4-position with respect to the carbonyl group. The replacement is effected by reacting with water a solution of the halogenotropone in a highly polar solvent such as formic acid, dioxane, alkylene glycols, glycerol, dimethyl sulphoxide, methyl and dimethylformamides and N-methylpropionamide; it may be the second stage in a two-stage process, of which the first stage constitutes halogenating a tropone. In Examples, (1) 2-ethyltropone is chlorinated, the product hydrolysed in aqueous formic acid and the cupric salt of 3-ethyltropolone is isolated after reaction with cupric acetate; (2) 3-isopropyltropolone was prepared analogously with Example (1), except that chlorination was effected in presence of FeCl3 and the Cu salt was decomposed with H2S; (3) tropolone was prepared analogously with Example (1), except that instead of the Cu salt, the Na salt was formed from the hydrolysis reaction mixture and NaOH, and was subsequently acidified.
