Abstract
Lubricants based on vegetable oils are a growing in attraction various applications. Environmentally friendly, vegetable oils and their derivatives constitute alternatives for a large variety of mineral based lubricants. New lubricating oils obtained from mixtures of vegetable oils (sunflower, SFO and rapeseed oil, RO) and synthetic diesters (di-2-ethylhexyl-adipate (DOA)) are studied. The physico-chemical characteristics of all these mixtures are given together with the differential scanning calorimetry (DSC) and thermal gravimetric (TG) analyses. Keywords: vegetable oils, diesters, environmentally lubricants, di-2-ethylhexyl-adipate, sunflower oil, rapeseed oil
