Abstract: Preparation of derivatives of benzene containing CF3 groups from the corresponding compounds containing CCl3 groups (e.g. trichloromethyl benzene) is carried out continuously with excellent yield rates by reaction with liquid hydrogen fluoride in an autoclave above 80 DEG C, (which latter exceeds the stoichiometric proportion by at least 25 mole %). The reactants are fed continuously into the autoclave. The reaction mixture preferably becomes pressurized to at least 20 atmospheres and homogeneous after having reached a certain filling level. The reaction mixture is thereafter withdrawn proportionally to its feeding-in rate. The mixture may be conveyed through one or several additional autoclaves with the final withdrawal of the reaction mixture being out from the terminal autoclave of this cascade. The fluorination products are well known starting and inermediate products for the preparation of dyestuffs and pesticidal compositions.

Abstract: 1,244,006. Monoazo-dyes. FARBWERKE HOECHST A.G. 4 Nov., 1968 [4 Nov., 1967], No. 52209/68. Heading C4P. Novel water-insoluble dyes of formula (wherein X is H, Cl or Br, E 1 is C 1-4 alkyl and R 2 is C 1-4 carboxylic acyl) are prepared by a conventional coupling reaction These dyes may be applied to synthetic fibres such as cellulose triacetate, cellulose - 2¢ - acetate, polyamide, polyurethane, and polyesters such as polyethylene terephthalate. The dyes are said to colour polyester fibres navy blue or violet.
