Abstract: ThisqualificationworkforMaster’sdegreeisdevotedtotheactualdevelopmentofthereconstructionoftheselectivepurificationofoilfractionswithfurfural. ThefieldoflubricantsinUkraine, aswellasinothercountries, cancoverallareasofeconomicactivitythatuseequipmentthatrequires a varietyoflubricantsformaintenance, includingolive Petroleumdistillateoilsareobtainedbyvacuumdistillationoffueloil. Petroleumresidualoils - tardeasphalting (residueaftervacuumdistillationoffueloil). Petroleumcompoundoils - bymixingbasedistillateandresidualoils. Theproductionofoilcomponentsfrominitialoilfractionsisbasedonthemethodsofremovingsuchundesirablecomponentsasacidiccompounds, unsaturatedhydrocarbons, sulfurousandresinouscompounds, polycyclicareneswithshortsidechains, solidparaffins. Forthispurpose, alkaline, selectiveoracidcleaning, aswellasdeparaffinizationanddeasphaltizationprocessesareused. Motoroilsconsistofthemain, basicmaterial - baseoils (75-95%) andactiveimpurities - additivesandadditives (5-25%), whichimprovetheiroperationalproperties. Thequalityofcommercialoildependsontheoil, themethodofobtainingthebaseoil, thedepthofchemicaltransformationandpurification.
