Abstract: Prodn. of phenylacetaldehydes of formula Ar-CH2-CHO (I) is effected by (a) contacting an epoxide or glycol deriv. of formula Ar-CHY-CH2Z (II) with a borosilicate zeolite catalyst in the gas phase at 70-200 deg.C under reduced pressure or (b) contacting a phenylglycidate ester of formula (III) with a zeolite, phosphate, supported H3PO4, supported H3BO3 and/or acidic metal oxide catalyst in the liq. or gas phase at 50-500 deg.C and 0.01-50 bar, Ar is phenyl with 0-5 substits. selected from halogen and opt. halogenated alkyl, alkenyl, alkylthio and cycloalkyl, Y and Z are OH, alkoxy, aryloxy or acyloxy or Y+Z is O, R6 is t-Bu or i-Pr.

Abstract: In the working up of organic materials which are normally crystalline, where the materials, as powder or liq. melt, are processed in a 2-shaft screw machine with the worm shafts rotating in the same direction, are expelled through a narrowed passage into a zone at low pressure, and are cooled and comminuted, the materials are heated to form a melt film during transit through the narrowed passage.

Abstract: Carboxylic acid chlorides of formula R-CO-Cl (I) in which R = 1-30C alkyl, 2-30C alkenyl or 2-30C alkynyl, are prepd. from carboxylic acids R-COOH (II) and phosgene COCl2 (III) in the presence of a catalyst adduct of phosgene and N-N-disubstd. formamides of formula R1R2NCHO (IV), in which R1 and R2 = 1-3C alkyl or R1 and R2 may together = a 4C or 5C alkylene chain which may be interrupted by an O atom or an N atom carrying a 1-3C alkyl or CHO gp., in which the (IV) is laden with 20-70 mol.% phosgene, and the (I) is recovered by phase sepn.

Abstract: 2-Methyl-2-alkenals of the formula I where R1 and R2 are each hydrogen, alkyl which may additionally carry aromatic radicals, or an aromatic radical, are prepared by isomerizing a 2-alkylacrolein of the formula II in the presence of hydrogen and of a catalyst which contains palladium and an oxide or salt of a rare earth metal as active components, at from 20 DEG to 120 DEG C. and under from 1 to 100 bar.
