Abstract
The present invention is a process for decreasing the acidity of a starting acidic crude oil by contacting an acidic crude with an effective excess of ammonia dissolved in said crude to form an ammonia-continuous oil discontinuous phase at a temperature and conditions sufficient to form the corresponding amide of the naphthenic acids. The process is useful in the processing of acidic crudes.

A process for decreasing the acidity of a start acidic crude oil, comprising:
- contacting an acidic crude with an effective excess of ammonia at a temperature and under conditions sufficient to form the corresponding amide.
A process for decreasing the acidity of a starting acidic crude, comprising:
- (a) contacting an acidic crude oil with an effective excess of ammonia at a temperature and under conditions sufficient to form the corresponding ammonium salt;
- and
- (b) contacting product of step (a) with an effective excess of ammonia at a temperature sufficient to form the corresponding amide of the naphthenic acid.
