FIELD: lubricants.
SUBSTANCE: invention relates to production of colorless basic lubricating oil containing more than 90% saturated hydrocarbons and less than 0.03% sulfur, and possessing viscosity coefficient 80-120. In particular, starting hydrocarbon feedstock is brought into contact with hydrogen in presence of hydrogenation catalyst at temperature above 300°C and WSHV value 0.3 to 2 kg oil per 1 L catalyst/h, after which rectification intermediate product is kept in contact with hydrogen in presence of catalyst at temperature below 280°C.
EFFECT: enabled formation of desired product with required properties.
