ABSTRACT:
The present invention concerns a process for preparing a basic additive for lubricating oils having an antiwear and detergent effect, the additive thus obtained and a lubricating composition containing the additive. The process consists of contacting an amino-acid in solution or in dispersion in the oil with a detergent, an alkaline-earth metal derivative, carbon dioxide in diluent oil, a hydrocarbon-based solvent, and a polar solvent in the presence of a nitrogen-based basic derivative.
