The article presents some results of investigating the effective adsorption ratio of base oil SN 100 on silica gel, determination of physico-chemical, electrical properties, and voltage stability of the oil fraction which is separated from base oil SN 100 by adsorption method on silica gel with the appropriate ratio of silica gel/base oil SN 100 = 140/100. Kinematic viscosity, flash point (closed cup), total acid number, and pour point were determined according to ASTM D445, ASTM D93-20, ASTM D974-22, and GOST 20287-91. The breakdown voltage was determined according to IEC 61086-2:2004. Voltage stability was evaluated by accelerated moisture resistance test. The determination results show that the physico-chemical and electrical properties of the oil portion which seperated from adsorption on silica gel reach the required values (according to the standard MIL-1-46058C), it allows use to make turbine oil and preservation oil for electrical and electronic equipment subject to high breakdown voltage.
