Novel bismuth alkyl-benzenesulphonates

摘要

Bismuth sulphonates of formulae (I) and (I) are novel. R<1> = 8-36C aliphatic hydrocarbyl; R<2> = H or R<1>. Also claimed is the preparation of these materials by reaction of the sulphonic acid and bismuth oxide in an optionally halogenated hydrocarbon solvent to from cpds. of formula (I) with the optional addition of water to form cpds. of formula (II).
