Abstract
Magnesium borate overbased metallic detergent having magnesium borate uniformally dispersed in an extremely fine particle size is prepared by using magnesium alkoxide and boric acid. The process for preparation involves reacting neutral sulphonate of an alkaline earth metal with magnesium alkoxide and boric acid under anhydrous conditions in the presence of a dilution solvent followed by distillation to remove alcohol and part of dilution solvent therefrom. The borated mixture is then cooled, filtered to recover magnesium borated metal detergent. The magnesium borated metal detergent exhibited excellent cleaning and dispersing performance, very good hydrolytic and oxidation stability, good extreme pressure and antiwear properties. Such a detergent can advantageously be used in a hydrocarbon composition.
