Thiadiazole Technology: -Motor Oil Antiwear -Grease Extreme Pressure Tom Karol, Ph.D. Research Director
1,3,4-Thiadiazole Chemistry –Physical /Performance Properties Liquid Wear/EP performance equivalent to or better than heavy metal technology Environmentally friendly wear/EP agent Ashless Biodegradable preferred Cost effective – Commercially viable process
Theory of Thiadiazoles as EP additives Theory of simple thiadiazole coordination Theory of dimer thiadiazole complexation Theory of poly thiadiazole coordination
VANLUBE 972 Metal Coordination Polydentate association
IR ABSORPTION Major shifts in peaks are further evidence for the complex formation: Compound Absorption Peaks (cm -1 ) DMTD disulfide bis-dimer 1487, 1435, 1406, 1262, 1212 Triethylene glycol monobutyl ether 1460, 1351, 1297, 1248 Complex, 40% monosulfide bis-dimer 1510, 1433, 1350, 1244
