Abstract: 1,156,709. Polyethers prepared by intramolecular dehydration of diols. BADISCHE ANILIN- & SODA-FABRIK A.G. 16 Nov., 1966 [17 Nov., 1965], No. 51331/66. Heading C2C. [Also in Division C3] Polyethers are prepared by inter-molecular dehydration of alkane diols having from 5 to 12 carbon atoms and terminal hydroxyl groups at elevated temperatures in the presence of a solid, non-basic dehydration catalyst, resulting water being removed from the reaction zone at the rate at which it is formed. Suitable alkane diols, which preferably have an unbranched carbon chain, are pentanediol-(1,5), hexanediol- (1,6), octanediol-(1,8), decanediol-(1,10) and dodecanediol-(1,12) or mixtures thereof. Examples of suitable catalysts, which are preferably weakly acidic, are oxides of aluminium, thorium, tungsten, vanadium, bismuth, molybdenum, titanium, osmium and chromium, or mixtures thereof to which zinc oxide or cadmium oxide may be added; boric acid; boron phosphate; borates and phosphates, especially weakly acid phosphates; aluminas, kieselguhr, silica gel; and porous materials, e.g. pumice or active carbon, impregnated with sulphuric acid, phosphoric acid, boric acid, acid phosphates or acid-forming metal oxides. Chromates or chromites of alkaline earth or heavy metals can be added to activate the catalyst. The reaction is carried out at a temperature of from 200‹ to 400‹ C. at a pressure between 50 torr and 10 atmospheres and the residence period in the reaction zone is between 1 and 1800 seconds. Water is removed from the reaction zone by azeotropic distillation or by simultaneously passing an inert gas, e.g. nitrogen or hydrogen, and the diol over the catalyst. The diol is preferably not reacted to completion so that it may act as solvent for the polyether formed. The resulting polyethers preferably have molecular weights between 300 and 1500.

[Also in Division C5] H 2 S and CO 2 are removed from gaseous mixtures containing them by scrubbing the gas mixture with an alkyloxazolidone, preferably with 3,5-dimethyloxazolidone-2, 3-methyloxazolidone-2, or 3-isopropyloxazolidone-2. The absorption is suitably performed under such conditions as 5-100, preferably 15-50, atmospheres, at temperatures of 10-40‹C., desorption of the solution being achieved by contact with air. Gas mixtures which may be so treated include natural gas, synthesis gas, industrial gases, coke oven gas and water gas.

[Also in Division C5] H 2 S and CO 2 are removed from gas mixtures by scrubbing the gas mixtures with a liquid dialkyl ester of a C 4-6 dicarboxylic acid. Absorption is suitably effected at pressures of 3-100 atmospheres and temperatures of 10- 40‹C, and desorption is achieved by partial or complete release of pressure in the presence of a current of air. The preferred ester is dimethyl glutarate. To increase the water solubility of the solvent, a substance such as an N-alkylformamide, an N-alkyl-2-pyrrolidone, or a tetra alkylurea may be added. Mixtures which may be so treated include natural gas, synthesis gas, town gas, industrial gas, coke oven gas, and water gas.

Amines are obtained by reacting an aldehyde or ketone with liquid ammonia and hydrogen under superatmospheric pressure, preferably at 90‹ to 130‹ C. under a pressure of 60 to 700 atmospheres gauge, in the presence of a catalyst comprising (a) nickel and/or cobalt; (b) chromium; and (c) at least one non-volatile mineral acid which is capable of being converted into an insoluble anhydride or an insoluble polyacid. Specified non-volatile mineral acids are sulphuric, vanadic, molybdic, tungstic, titanic and phosphorus and boric acids, the catalyst may also include manganese, cadmium, zinc and/or silver, and it may be used without a carrier or supported on a carrier material capable of eliminating water.

Abstract: 1,127,971. Recovering aromatic hydrocarbons. BADISCHE ANILIN- & SODA-FABRIK A.G. 28 Jan., 1966 [30 Jan., 1965], No. 3860/66. Heading C5E. Aromatic hydrocarbons are recovered from hydrocarbon mixtures containing aromatic and paraffinic hydrocarbons with or without olefins and naphthenes by a selective extraction process (e.g. liquid-liquid extraction or extractive distillation) in which the solvent is an aliphatic dicarboxylic imide, which may be substituted on the N-atom by an alkoxy or esterified hydroxy group. The solvent may contain up to 30% water and/or other additives, e.g. N- substituted pyrrolidones, piperazines, polyhydric alcohols, urea, and urea derivatives. In a liquid-liquid extraction process a backflow of a hydrocarbon solvent may be used, e:g. propane, butane, pentane, hexane, or iso-octane. A variety of mineral oil fractions which may be treated is mentioned, and the process is exemplified by a liquid-liquid extraction process in which a mixture of benzene, cyclohexane, cyclohexene, and n-hexane is introduced into the middle of a sieve plate column, N-hydroxyethyl succinimide acetic ester as the top, and iso-octane at the bottom. Raffinate from the top of the column, after removal of iso-octane, contains less than 1 % benzene; and extract from the bottom of the column, after removal of the imide solvent, contains 99À6% benzene.

Abstract: Oil soluble condensation products are prepared by interacting (a) 1 mole of a dialkyl benzene with (b) 1.5 mole to 6 mole of HCHO or an equivalent amount of a nitrogen-free formaldehyde generator at 70-180 DEG C., using an acid catalyst, neutralizing the product or washing out the acid and treating the product with (c) 10-40 times its weight of ethylene oxide or propylene oxide. The alkyl groups in (a) may contain up to 20 carbon atoms. (a) and (b) may be reacted in the presence of 1 mole of H2SO4 as catalyst. The second reaction may be under a pressure of 2-20 atmospheres in the presence of a caustic alkali as initiator and an inert solvent. Both reactions may be effected under an inert atmosphere and (a), (b) and/or (c) may be replaced by mixtures of reactants. In an example formalin and di-isopropylbenzene are interacted and the product dissolved in diisopropylbenzene. KOH is added as initiator followed successively by propylene oxide and ethylene oxide. The product is extracted from the solvent and dissolved in a mixture of di- and mono-methyl naphthalene.
