Lashkhi, V. L. published the artcileMicrocalorimetric study of the adsorption of additives for oils on metal, Computed Properties of 866-23-9, the publication is Neftekhimiya (1974), 14(3), 491-4, database is CAplus.
The adsorption heat, included in some formulas determining the wear, was determined by microcalorimetry, using cyclohexane as carrier liquid and solvent. The higher adsorption heat (≥2) prevailed for Sulfol [[CCl3(CH2)4]2S] [14146-66-8], CCl3(CH2)6P(O)(OEt)2 [53280-04-9], and DF-1 (Ba O,O-dialkyl dithiophosphate) [39360-55-9], while the lower one (≤1) for: MeP(O)(OEt)2 [683-08-9], PhP(O)(OEt2) [1754-49-0], and Zn O,O-diisobutyl O,O-diisooctyl dithiophosphate [54244-07-4]. The antiwear properties of the additives increased with increase of the heat of their adsorption on the metal, according to tests by the frictional machine at low contact loads.
Neftekhimiya published new progress about 866-23-9. 866-23-9 belongs to chlorides-buliding-blocks, auxiliary class Aliphatic Chain, name is Diethyltrichloromethylphosphonate, and the molecular formula is C5H10Cl3O3P, Computed Properties of 866-23-9.
