Abstract: - 25 - O.Z. 0050/38673 4-Formyltetrahydropyrans of the general formula I (I) where R1 is hydrogen, C1-C12-alkyl, C2-C12-alkenyl, C1-C6-alkoxy-substituted C1-C12-alkyl, C4-C12-cycloalkyl, unsubstituted or substituted aryl, hetaryl or aralkyl, or an unsubsituted or substituted, saturated or unsaturated 5membered or 6-membered ring which may be interrupted by N, O or S, are prepared by a process in which a pyran derivative of the general formula II (II) where R1 is as defined above, R2 and R3 are each OH or together are an oxygen atom and thus form an oxirane ring, and R4 is hydrogen where R2 and R3 are each OH, and is hydrogen or tert-butoxycarbonyl where R2 and R3 together are an oxygen atom, is treated at elevated temperatures with a catalyst selected from the group consisting of zeolites, phosphates, boric acid on a carrier and silica or mixtures of these. Novel 4-formyltetrahydropyrans are also proposed.

Abstract: Aqueous solutions of glyoxal which contain acids are purified by treatment with a solution which contains from 20 to 60% by weight of a tertiary amine and from 80 to 40% by weight of an alcohol which is not infinitely miscible with water, the treatment being carried out by mixing the two solutions during a residence time of less than 5 minutes.

Abstract: 1,132,865. Making combustible gas. BADISCHE ANILIN - & SODA - FABRIK A.G., and METALLGESELLSCHAFT A.G. 10 March, 1966 [11 March, 1965], No. 10508/66. Heading C5E. A cracked gas of high CH 4 content is made by cracking C 2 to C 30 hydrocarbons with steam at atmospheric or superatmospheric pressure at a temperature of from 350‹ to 550‹ C. The catalyst comprises 35 to 50% b.w. Ni, a carrier material, e.g. alumina, magnesia, zirconium dioxide or titanium dioxide, and an hydraulic binder, e.g. calcium aluminate, and the inner surface area of the catalyst must be at least 15 m 2 /gm. An alkali metal compound or a chromium compound may be added to the carrier. Pressures up to 100 atmos. are mentioned, but 20 to 60 atmos. are preferred, and catalyst surface areas up to 200 m 2 /gm are mentioned, with 15 to 40 preferred. The cracked gas may be further catalytically cracked at above 550‹ C. to increase the H 2 content, or at below 350‹ C. to increase the CH 4 content, and the initial cracked gas may be mixed with a cracked gas rich in H 2 and CO to provide town's gas. Three specific examples are described, in one of which, see Fig. (not shown), steam at 500‹ C. enters at (4) a reactor (1) to heat catalyst-filled tubes (2) externally, the steam leaving at (5) for delivery to a line (6) through which a mixture of desulphurized gasoline and hydrogen is delivered to the tubes (2). Examples of feedstocks are given.

Abstract: Disclosed are processes for preparing phenylacetaldehydes of the structure (I) (see fig. I) where the substituents X are 2,4-dichloro, difluoro, tri-fluoro, tetrafluoro, p-trifluoromethyl, 2-methyl-4-fluoro, haloalkoxy or haloalkylthio radicals or are adjacent CL, F, CF3, alkyl, alkoxy, haloalkoxy and/or haloalkylthio radicals. Some of these compounds which are useful as intermediates for the preparation of insecticides, are new.

Abstract: Methyl formate is prepared by reaction of carbon monoxide and methanol at elevated pressure and elevated temperature in the presence of an alkali metal methoxide by A) mixing the starting substances in a mixing zone, partially allowing them to react, saturating the reaction solution with CO and B) carrying the reaction to completion in one or more subsequent reaction zones without addition of further starting compounds.

Abstract: A process for preparing formic acid by thermal cleavage of quaternary ammonium formates of the general formula I (* CHEMICAL STRUCTURE *) (I) where R1, R2 and R3 are C1- to C14-alkyl, C3- to C8-cycloalkyl, aryl or C7- to C16-aralkyl, or together are 1,4- or 1,5-alkylene which is unsubstituted or substituted one to four times by C1-to C4-alkyl, with the proviso that the sum of the carbon atoms of R1, R2 and R3 in the quaternary ammonium formates I is 7 to 40, comprises carrying out the cleavage in the presence of secondary formamides of the general formula II (* CHEMICAL STRUCTURE *) (II) where R4 and R5 are C2- to C10-alkyl, C3- to C8-cycloalkyl, aryl or C7- to C16-aralkyl, or together are 1,4- or 1,5-alkylene which is unsubstituted or substituted one to four times by C1- to C4-alkyl, which formamides boil 30 degrees to 150 degrees C. lower than the tertiary amine of the general formula III (* CHEMICAL STRUCTURE *) (III) where R1, R2 and R3 have the abovementioned meanings, contained in the formate I.
