ADDITIVES WITH A REDUCED TENDENCY TO EMULSIFY, WHICH IMPROVETHE LUBRICATING ACTION OF HIGHLY DESULPHURISED FUEL OILS

摘要

The invention relates to an additive for improving the lubrication capacity of fuel oils with a maximum sulphur content of 0.035 wt. %. Said additive contains at least one ester of a bivalent or polyvalent alcohol and a mixtur e of unsaturated and optionally saturated fatty acids, whose carbon chain lengths are between 8 and 30 carbon atoms, the aforementioned esters having an OH value less than 200 mg KOH/g ester and an iodine value greater than 100 g I/100 g ester. The invention also relates to fuel oils with a maximum sulphu r content of 0.035 wt. %, which contain the inventive additives. The novel additives exhibit less tendency to emulsify than the additives in prior art.
