ABSTRACT:
The invention relates to a process for treating naphthenic acid-containing whole crudes or fractions thereof to reduce or eliminate their acidity by contacting the acidic whole crude at a temperature of from about 60.degree. C. to 170.degree. C. with a neutralizing amount of alkali metal trialkylsilanolates. The process has the additional benefits of reducing materials handling problems associated with treating crudes using liquid solvents and in reducing emulsion formation.
