| abstract |
A highly basic lithium sulphonate, having a TBN of at least 250 mgKOH/g is prepared by heating a mixture of lithium hydroxide monohydrate and a solvent to remove water as an azeotrope of water and said solvent prior to formation of the lithium salt of the sulphonic acid and subsequently overbasing with carbon dioxide. |
