  • British Patent- Specification No. 785,196 describes fuels including gasoline, containing mono-valent me :al salts of alkyl salicylic or napthenic acids to prevent corrosion.
  • British Patent Speci ication No. 818,323 describes the addition Of alkaline earth metal compounds to light hydrocarbon mixtures such as gasoline.

  • the preferred metal suggested is potassium.

  • the metal salts of mono and diesters of sulphosuccinic acid can be represented by the following formulae:
  • R and R' are aliphatic hydrocarbyl groups containing from 4 to 20 carbon atoms a ⁇ described above.
  • the alkali metal or alkaline earth metal salts of the diesters of sulphosuccinic acid are preferred because they have been found to be soluble in gasoline to an extent which will permit the desired level of addition of alkali metal or alkaline earth metal to the gasoline.
  • the chain length of the aliphatic hydrocarbyl group or groups has 4 to 20 carbon atoms. It is considered that when chains less than 4 carbon atoms are used the resulting molecule is too polar for gasoline solubility. A carbon chain length of more than 20 is considered unnecessary.

  • alkali and alkaline earth metal salts even though soluble in gasoline, are unsuitable for use as a gasoline additive because they have a strong tendency to emulsify water into gasoline. It has been found that this tendency to form emulsions is minimised when the chain length of the aliphatic hydrocarbyl group is 6 to 12 carbon atoms, and preferably 8 carbon atoms, and particularly so where these groups are isooctyl or 2-ethylhaxyl.
