Abstract:
The influence of additives of cholesterol compounds on the optical properties of liquid lubricants based on mineral and synthetic oils was studied. It is shown that the introduction of cholesterol esters in vaseline oil and polyethylsiloxane liquid leads to
a change in their optical properties, which is expressed in the direct dependence of the rotation angle of the plane of polarization
of light on the content of cholesterol esters in liquid lubricants. The effect on this dependence of the length of the radical of fatty
acid in the ether of cholesterol was established.
Keywords:cholesterol esters, optical properties of solutions, radical of fatty acid in cholesterol ester, liquid lubricating media.
