Abstract: Polyfunctional alcohols with at least two alcoholic hydroxy groups are effective agents for dispelling fog and clouds. Preferred solid compounds are the so called sugar alcohols, saccharides and polyvinyl-alcohol, as liquid compounds or compounds with a low melting point alkane-diols, -triols or polyols or their reaction products with oxalkylating agents. The said compounds are sprayed into fog or clouds in finely dispersed form. They may be used, optionally together with other fog and clouds dispelling agents.

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.
