Abstract: Phosphorothionyl disulphides are prepared by reacting an organic thiophosphoric acid with hydrogen peroxide under conditions such that either the thiophosphoric acid is added to the hydrogen peroxide or the thiophosphoric acid and hydrogen peroxide are introduced into the reaction vessel such that there is never more than 10 mole % excess of thiophosphoric acid (compared with the hydrogen peroxide) added to the reaction vessel. In this manner phosphorothionyl disulphides which are useful as ashless lubricating oil antioxidants and anti-wear additives, can be prepared in good yield and with very low acid number.
