MANUFACTURING METHOD OF A DIOCTYL SEBACATE FOR ANTICORROSIVE OIL NOT HARMFUL FOR HUMAN BODY AND HIGH BIODEGRADABILITY

摘要

PURPOSE: A manufacturing method of a dioctyl sebacate for anticorrosive oil is provided to provide a dioctyl sebacate with high purity while obtaining excellent corrosion resistance, lipid resistance, and oil-staining resistance.;CONSTITUTION: A manufacturing method of a dioctyl sebacate comprises: a step of removing 2-etylhexylalcohol and sebacic acid through a free fatty acid removing reaction; a step of removing free alcohol from the result and cooling the result to synthesize a dioctyl sebacate reactant; a step of reacting caustic soda aqueous solution with the dioctyl sebacate reactant and deoxidizing and washing the resu and a step of reacting an absorbent into the result, filtering the same, and stirring the mixture.;COPYRIGHT KIPO 2013
