ABSTRACT:
Azole and azoline disulfides useful as corrosion inhibitors and antiwear agents are prepared by the halogen-induced coupling of a thiol reactant e.g., hydrocarbyl mercaptans, with a metal azole thiolate, e.g. the potassium salt of 3,5-bis-mercapto 1,2,4-thiadiazole or 2,5-bis-mercapto 1,3,4 thiadiazole in a 2-phase reaction medium comprising a mixture of a hydrocarbon and water.
