    Abstract: 1532506 Emulsion concentrates of waterinsoluble biocides HOECHST AG 29 Jan 1976 [31 Jan 1975] 03511/76 Heading A5E An emulsion concentrate of a water-insoluble organic biocide which is sensitive to hydrolysis in an organic non-polar solvent which is free from hydroxyl groups, contains an anionic emulsifier and optionally an ionic emulsifier, and has as viscosity reducing agent a compound of formula: in which each of R 1 and R 2 is an alkyl group having from 1 to 4 carbon atoms, an alkylcarbonyl group having from 2 to 4 carbon atoms or a carbamoyl group having from 1 to 4 carbon atoms, X is an alkylene group having from 2 to 4 carbon atoms and n is in the range of from 1 to 20. The biocide may be a phosphoric or thiophosphoric acid ester and the solvent may be benzene, toluene, xylene or kerosine. Viscosity reducing agents used are ethylene glycol dimethyl and diethyl ethers; di-, tri- and tetra-ethylene glycol dimethyl ethers; diethylene glycol dibutyl ether; methyl-tetraglycol t-butyl ether; methyl glycolbutyl glycol-, and methyldiglycol-acetates; glycol diacetate; ethyl glycol- and methyldiglycolmethylurethanes; propanediol- and butanedioldiacetates; and butanediol dimethylurethane.

    Abstract: 1328933 Chlorinated paraffin sulphonic acids and salts FARBWERKE HOECHST AG 11 April 1972 [16 April 1971] 16602/72 Heading C2C [Also in Divisions A5 and C5] The calcium salt of chlorinated n-paraffin sulphonates is prepared by passing chlorine gas into a 60% aqueous paste of a sodium salt of a straight chain paraffin sulphonic acid having 13 to 18 C atoms in the alkyl chain, exposed to ultra-violet light produced by a mercury high vapor pressure immersion burner. 1À5 gram atoms of chlorine per mol of paraffin sulphonate is taken up during the reaction. The free chlorinated paraffin sulphonic acid is isolated and neutralized with calcium hydroxide. The corresponding magnesium and barium salts are obtained by neutralizing the free acid with magnesium and barium hydroxide respectively. The zinc salt is produced from the free acid by treatment with zinc carbonate and the aluminium salt by treatment with aluminium triisopropylate.
