Abstract
Abstract The load-carrying capacity of liquid lubricants having a kinematic viscosity of 2 to 1500 mm2/s at 40 DEG C. can be substantially improved by the addition of oil-insoluble, dispersible aromatic compounds which are chlorine-substituted in the nucleus. The compounds, which consist of 1 to 4 completely unsaturated or partially saturated aromatic moieties which may contain hetero-atoms and are linked to one another through a simple direct bond, a double bond or through -O-, -S-, -N(R)-, -N=, alkylene, -NHCO-, -N=CH-, -N=N-, -N=NCH(COCH3)CONH, -CH=N-N=CH- or =N-(Y)-N=, contain from 2 to 24 aromatic chlorine atoms. The combination of the additives of the invention with conventional antiwear additives has been found to be particularly advantageous.
