| titleOfInvention |
Overbased alkali metal additives |
| abstract |
A process for making an oil solution of a highly basic alkali metal compound which comprises n (a) heating alkali metal hydroxide with an alkoxyalkanol and a solvent to remove water as an azeotrope with alkoxyalkanol and said solvent; n (b) adding to the mixture surfactant; n (c) thereafter introducing carbon dioxide into the reaction mixture so as to react with the basic compounds therein; n (d) hydrolysing the reaction mixture; and n (e) removing solvent by distillation, n base oil being added to the process during one of steps (b), (c), (d) and (e) so that the desired product is obtained. |
