On May 15, 2021, Hu, Chenghong; He, Xi; Han, Yunyan; Ye, Xiangyuan; Fan, Mingjin; Zhou, Feng; Liu, Weimin published an article.HPLC of Formula: 3319-31-1 The title of the article was High performance lubricants prepared from Naphthalene-1,4,5,8-Tetracarboxylic acid: Synthesis, physicochemical and Tribological properties. And the article contained the following:
Ester oils (1,4,5,8-4Cn) were synthesized through esterification of naphthalene-1,4,5,8-tetracarboxylic acid with aliphatic alcs. The mol. structures were confirmed with 1H NMR, 13C NMR, FT-IR and elemental anal. Their KV, VI, FP, PP, oxidation and thermal stabilities, friction reducing and anti-wear performances were measured. The results demonstrate that the 1,4,5,8-4Cn have obviously higher thermal and oxidation stabilities than the existing esters DOS, PIS and Phe-3Ci8. They also have predominant tribol. behavior at both 50°C and 120°C. Analyzing from the results of ECR, QCM and XPS, it could be concluded that strongly and orderly physicochem. adsorption of the 1,4,5,8-4Cn mols. on the sliding surfaces is the critical factor for these oils to demonstrate excellent tribol. performance for steel contacts. The experimental process involved the reaction of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate(cas: 3319-31-1).HPLC of Formula: 3319-31-1
