Abstract

Cellulose fatty esters with different fatty acids as lauric, myristic, palmitic, stearic and oleic acid having same degrees of substitution (DS ∼ 2.0) were prepared homogeneously using 1-butyl-3-methylimidazolium chloride ([C4mim]+Cl−). All samples were characterized by IR and NMR. The triboevaluation in terms of average friction coefficient was done by nanotribometer using 3000 ppm solution of each ester in polyol (pentaerythritol tetraoleate) which is taken as biolube reference fluid. The cellulose esters are found to show antifriction character in the order as myristate > palmitate > laurate > stearate > oleate.

Graphical abstractThe graphics shows experimental setup of the nanotribometer which was used for the evaluation of the antifriction property of the synthesized cellulose fatty esters. The decreased friction coefficient in the case of cellulose myristate sample is also shown along with the image of the vial having its 3000 ppm solution in the polyol lube base.Figure optionsDownload full-size imageDownload as PowerPoint slide
