| Abstract: | The conditions for synthesis of overbased lithium sulfonate were investigated in this paper.Various performances of lithium sulfonate,such as its corrosiveness,high temperature detergency,oxidization stability,wear resistance,dispersity,bubble ability and acid neutralization capability were evaluated in a 15W/40 thickened oil.On comparison with other sulfonates,the overbased lithium sulfonate exhibited a lowest sulphate ash,a best detergency and a moderate corrosiveness in 15w/40CD and 15w/40SD oil formulations.However,the weak wear resistance was its only disadvantage. |
