Abstract
Abstract Compounds made by reacting a vicinal diol with a hydrocarbyl phosphite and then borating the resulting product have been found to be effective friction reducers when added to lubricants or fuels. This is true in any use of lubricants, but is especially true when they are used in internal combustion engines. In the latter case, the fuels used, when they contain the additive, aid in the reduction of friction in the engine.
