Abstract:

Dietherdithiophosphoric acids with the general formula ROCH2CHCl CHO2PSSH were interacted with ethylene oxide and epichlorohydrin and the resultant compounds tested as antiseize and antiwear additives in an attempt to develop organic compounds combining at least three active elements in a single molecule. Analysis of the products of interaction between dietherdithiophosphoric acids and ethylene oxide shows that they are very close in composition to trietherdithiophosphoric acids. The resultant trietherdithiophosphoric acids were tested as antiseize and antiwear additives in AK-15 oil on a four-ball tetrahedral friction machine with ShKh-6 steel balls. The results show that both additives have high antiseize and antiwear properties with about equal numerical values for the generalized wear index.
