Abstract
An improved process for reducing mercaptan (thiol) concentrations of sour petroleum distillates includes the treatment of these sour distillates with peroxy compounds, preferably tertiary butyl hydroxide and cumene hydroperoxide in the presence of oil-dispersible organic amine compounds such as quaternary ammonium hydroxide salts and alkalene polyamines. The preferred organic amine catalyst is Primene 81-R.
