Abstract: An improved process for the production of Alpha chlorocarboxylic acid chlorides by reaction of a carboxylic acid chloride with chlorine at elevated temperature, wherein the improvement consists in carrying out the reaction in the presence of sulfuric acid. Alpha -chlorocarboxylic acid chlorides are suitable for the production of plant protection agents.

Abstract: Dehydrogenation of isobutyronitrile, ethylbenzene or methyl isobutyrate with iodine and oxygen into methacrylonitrile, styrene or methyl methacrylate at 400 DEG to 800 DEG C is carried out in a reaction chamber in which there are arranged, in the direction of flow of the bulk of the reactants introduced through a nozzle, coaxially from inside to outside first a mixing zone and then a circulation tube.
