Title: Improvements in or relating to a Process for the Production of Ethers
Inventor: EVANS RODERICK JAMES DARLEY
IPC: C07C29/52
Filed: 1965-08-11
Abstract: 1,150,345. Ethers of polyoxyalkylene glycols. IMPERIAL CHEMICAL INDUSTRIES Ltd. 4 Aug., 1966 [11 Aug., 1965], No. 34369/65. Heading C2C. Ethers of polyoxyalkylene glycols are prepared by reacting at least one alkylene oxide of 2 to 4 carbon atoms with a mixture containing one or more monohydric alcohols and one or more hydrocarbons which are unreactive towards alkylene oxides, the ethers being more easily separated from the hydrocarbons than the original alcohols by distillation. The preferred alkylene oxides are ethylene or propylene oxides and the hydrocarbons are preferably paraffins. A preferred process involves reacting a mixture of paraffins having 10 to 20 carbon atoms in the liquid phase with molecular oxygen in the presence of a boric acid or anhydride. The boric acid or anhydride is present in concentrations between 2 and 25% by weight of the reaction medium and is sufficient to form esters with all the alcohol produced; the molecular oxygen is supplied in concentrations of 2 to 10% of the gas mixture which is otherwise inert to the reaction, e.g. containing nitrogen. The reaction is preferably carried out at pressures slightly above atmospheric, and temperatures between 140‹ and 200‹ C. The alcohol-containing product is then distilled to provide at least one fraction consisting substantially only of non-alcoholic material, or only of alcohols, leaving a paraffin/alcohol mixture in which the components cannot easily be separated by distillation. The reaction of the alcohol with the alkylene oxide is preferably carried out at pressures between 1 and 5 atmospheres in the presence of acidic or alkaline catalysts, e.g. boron trifluoride etherate in 0À02 to 3% concentrations by weight of the reaction medium, at 20-85‹ C., or sodium or potassium alkoxides at concentrations between 0À2 and 5% by weight and at 80-200‹ C. An alternative embodiment comprises condensing at most 4 molecules of ethylene oxide with each molecule of a secondary alcohol in the presence of BF 3 , neutralizing the resultant reaction mixture and contacting the product with more ethylene oxide at temperatures between 80‹ and 200‹ C. in the presence of alkaline catalyst until at most 20 molecules of oxide/molecule of alcohol have reacted, and removing the unchanged non- alcoholic material after either the acid or the alkaline condensation by distillation after neutralization. The unreacted paraffin may be recycled to the oxidation stage.

Filed: 1928-12-01
Abstract: 322,102. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Dec. 1, 1928. Grant of Patent revoked. Polymerization products of gamma-butylene and its homologues are obtained in good yields by treat. ing the said hydrocarbons or gases containing the same with about 50 to 60 per cent sulphuric acid and heating the solution obtained, for example, to about 100‹ C. for 30 minutes. The process can be carried out at ordinary or at elevated pressures. It is advantageous to arrange for the solution to be heated to act as the cooling agent for the sulphuric acid which has been freed from the reaction products and which is to be cooled. The Specification gives an example in which a gas containing 10 per cent of y-butylene and 4 per cent of trimethylethylene is absorbed by means of 55 per cent sulphuric acid solution, the latter being subsequently heated to about 100‹ C. to bring about polymerization. The product contains 80 per cent of dimolecular polymers and 20 per cent of higher polymers.
