Abstract

1435253 Production of methanol M M KARAVAEV A A LENDER S M SHTEFAN N I ZOTOVA A G KRASNYANSKAYA V A IVASCHENKO V N FROLOY A A BELETSKAYA J V LENDER and G V GREBENIK 13 June 1974 26346/74 Heading C2C Methanol is prepared by reacting carbon monoxide and carbon dioxide with hydrogen in a gas mixture that also comprises nitrogen, argon and methane at not more than 300‹ C. at a gauge pressure of 20-100 atm. in the presence of a copper-containing catalyst, the volume ratio (H 2 - CO 2 ) : (CO + CU 2 ) being less than 2, the volume ratio H 2 : CO not less than 2, and the total content of nitrogen, argon and methane being 14À3-50% by volume of the gas mixture. The gas mixture may contain unsaturated hydrocarbons (e.g. ethylene or acetylene), preferably not more than 1% of the mixture. In a preferred embodiment, the product gas is cooled by heat exchange with the incoming gas, further cooled to condense methanol, and uncondensed gas is recycled. The catalyst used contains copper, zinc and aluminium oxides. 1435261 Benzofuran-derived aminoalkoxyphenyl ketones SMITHKLINE CORP 20 Sept 1974 [21 Sept 1973] 41001/74 Heading C2C The invention comprises compounds of formula and their pharmaceutically acceptable acid addition salts, wherein R 1 is H, halogen, CF 3 or C 1-4 alkyl or alkoxy; R 2 is H, C 1-4 alkyl or Ph or PhCH 2 , optionally substituted by halogen, CF 3 , C 1-4 alkyl or alkoxy, or NH 2 which may be mono- or di-C 1-4 alkyl-substituted; R 3 is benzoyl which is (a) substituted by in which each R is H, or one of them may be Me or Et, X is H or C 2-4 alkanoyl and Z is N(X)(C 1-4 alkyl), N(C 1-4 alkyl)2, NHCH 2 Ph, piperidino, pyrrolidino, morpholino or succinimido, and (b) optionally substituted by (Y) 1-2 where Y is halogen or C 1-4 alkyl or alkoxy. These compounds are prepared by reacting analogues of (I) in which R 3 is (optionally substituted) glycidyloxybenzoyl or 3-chloro-2-hydroxypropoxybenzoyl with HZ, followed optionally by O- and/or N-acylation. Starting materials described are m-CF 3 C 6 H 4 - COCH 2 Br; 3,4-Cl(HO)C 6 H 3 C0 2 Me; 3,4-Cl(Me-O) C 6 H 3 CO 2 H and its acid chloride and methyl ester; further analogues of (I) (in which when R 2 is or contains Ph, the latter may be NO 2 - substituted) where R 3 is H, hydroxybenzoyl, acetoxybenzoyl, alkenyloxybenzoyl or anisoyl; 2-(substituted benzoyl)-benzofurans, and certain 2,3 - dihydrobenzofuran - 3 - ols, benzylbenzofurans, and hydrazones related thereto; and 2- butyrylbenzofurans. Therapeutic compositions having coronary vasodilator, antianginal and hypotensive activity comprise compounds of the above formula.
