    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.

    Abstract: Addition products from ethylene oxide-propylene oxide block polymers of the formula wherein R denotes methyl or ethyl, n and m are numbers which are so chosen that the content of polyethylene oxide constitutes 5 to 80% of the molecular weight of the total molecule and p is a number larger than 10, and bis-glycidyl ethers of the formulae or +TR wherein the R1's can be identical or different and denote hydrogen, C1-C4-alkyl or halogen, in particular chlorine, A denotes a direct bond, a sulfonyl or cyclohexyl group or a group of the formula R2 denotes hydrogen, methyl or phenyl and a denotes an integer from 0 to 10. These addition products are used for breaking petroleum emulsions.
