Effect of nanovolumes of additives on the properties of motor oils. Theoretical principles

A method is proposed for scattered light correlation spectroscopy for objective evaluation of the effect of water, oxidation products, and particulate contaminants on the size of colloidal formations in petroleum oils with additives. It was shown that to increase the colloidal stability — resistance to separation of oils with additives — and correspondingly improve their performance properties, it is necessary to take into account the intermolecular interactions of the additives in composites and to ensure the minimum change in them under the effect of external factors. The mechanism of the reaction of the additives and their selection for ensuring the assigned performance properties of lube oils is theoretically substantiated. __________ Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 3, pp. 43–45, May–June, 2008.

Evaluating the anticorrosion properties of motor oils containing additives

Conclusions A study has been made of the effects of oxidation period (from 10 to 50 h), temperature (from 140 to 180°C), and oxidation catalyst (copper naphthenate) on the anticorrosion properties of 10 additives of different types; it has been demonstrated that the potential corrosivity of DS-11 base oil is most effectively improved by the additives LZ-23k and DF-1.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 6, pp. 46–51, June, 1968.
