Study in fatty acids of tall oils and their products of esterification by the method of IR spectrometry for analytical control of preparation of esters

Abstract

Abstract Tall oil fatty acids are a by-product of the sulfate pulping of cellulose. The field of application of tall oil fatty acids is currently limited to the production of polyhydric alcohol esters (glycerol, etriol, and pentaerythritol, primarily, for the production of alkyds); ethanolamides; disproportionated and dimer acids (including amides based on them); imidazolines; salts; as well as lower alkyl esters. However, tall oil fatty acids have the potential to be used as a basis for the synthesis of motor oils and their additives, additives to diesel fuel, as well as raw materials for the production of biodiesel fuel.
