Abstract: Process for halogenating cyclopropyl methyl ketone (I) comprises reacting (I) with a dihalophosphorane of formula R3PHal2 (II) at 80-200 deg C. R = 1-20C saturated or unsaturated aliphatic hydrocarbyl group or a phenyl or (1-4C alkyl)phenyl group optionally substituted by 1-2 of F, Cl and/or NO2; and Hal = Cl, Br or I. Also claimed are (i) a halogenation product obtained as above; and (ii) the production of cyclopropylacetylene (III) by treating the halogenation product with a strong base, especially KOH in a glycol ether, at -33 to 250 deg C.

Abstract: 1-(alkanoyl halide)-2-carboxamido-1,4,5,6-tetrahydropyrazines of general formula (I), in which R , R and R are the same or different and represent a straight or branched-chain C1 to C8 alkyl group, a C5 to C6 cycloalkyl group, a C6 to C7 methylene cycloalkyl group, a C6 to C10 aryl group or a C7 to C12 aralkyl group or in which the radicals R and R are bonded together and jointly with the exocyclic non-carbonylic carbon atom C form a 5 to 6-component cycloaliphatic ring and R has the above meaning or in which R is hydrogen and R and R are the same or different and have the above meaning, R is a C1 to C19 alkyl halide group containing one or more identical or different halogen atoms selected from fluorine and/or chlorine as the halogen substituent and in which R is hydrogen or a tertiary butyl oxycarbonyl or a benzyl oxycarbonyl group. Also described is a process for production of said compounds and the use thereof.

Abstract: Described is a method of separating a catalyst from a mixture of the catalyst with oligomers of vinyl oxirane such as is produced in the isomerization of vinyl oxirane to 2,5-dihydrofuran and from which practically all the low-boiling constituents have been distilled off. The mixture of oligomers and catalyst, consisting essentially of: a) an onium iodide, b) a Lewis acid selected from the group consisting of the chloride, bromide and iodide of cobalt, bismuth, tin and zinc and optionally and c) a donor ligand is intensively mixed (1) with a hydrocarbon or chlorohydrocarbon having 5 to 14 carbon atoms; (2) of the two phases formed, the phase containing the catalyst is separated off; and (3) the catalyst is recovered by distilling off the solvent.

Abstract: A process for the preparation of 2,5-dihydrofurans of the general formula I I where R1, R2, R3, R4, R5 and R6 are identical or different and are hydrogen or C1-C4-alkyl, by the catalytic rearrangement of 3,4-epoxy-1-butenes of the general formula II II comprises the rearrangement being catalyzed by a system which contains components A, B and C, at from 60 DEG to 200 DEG C., where A is a halide of an alkali metal or alkaline earth metal or an onium halide, B is an organic solubilizer for component A, and C is a Lewis acid or elemental iodine, with the proviso that at least one of components A or C is an iodide. 2,5-Dihydrofurans are intermediates for the well known tetrahydrofurans which are used as solvents, e.g. for polyvinyl chloride, polyvinylidene chloride, and other difficultly soluble organic materials, and are also used as monomers for the preparation of polytetrahydrofurans.

Abstract: Prepn. is claimed of aldehydes by gas-phase hydrogenation of aromatic carboxylic acids, or aliphatic carboxylic acids which possessup to one hydrogen atom alpha to the carboxyl or esters or anhydrides of these acids, at temps. of 300 to 450 deg.C and pressures of 0.1 10 bar aided by special iron as catalysts. Cpds are prepd. by burning carbonyls in air and oxygen to the required level of iron oxide, and may be impregnated into an inert carrier of suitable particle size and mixed with an appropriate lubricant for use in a fluidised bed reactor.
