    摘要: New sulfonated bismuth compounds and the preparation thereof are described. These new compounds can be represented by the following general formulae: ##STR1## where R.sub.1 represents a monovalent linear or branched aliphatic hydrocarbonaceous radical containing 8 to 36 atoms of carbon, and R.sub.2 represents an atom of hydrogen or a monovalent linear or branched aliphatic hydrocarbonaceous radical containing 8 to 36 atoms of carbon. These compounds, which possess surface-active and wear-fighting properties, are used as fuel additives. They can also serve as starting materials in the manufacture of overbased colloidal products usable as lubricant additives by carbonation of at least one calcium, barium, or magnesium oxide or hydroxide, the carbonate formed being kept as a colloidal dispersion in an organic medium by using at least one of the sulfonated bismuth compounds (I) and (II).
