Abstract

PROCEDIMIENTO PARA OBTENER ALFA-TOCOFEROL. SE AMINOALQUILA UN CONCENTRADO DE TOCOFEROLES, SE PONE EN CONTACTO ESTE PRODUCTO CON UN DISOLVENTE ORGANICO NO POLAR INMISCIBLE CON AGUA, PARA PROPORCIONAR DOS FASES, EN QUE DICHA FASE DE DISOLVENTE NO POLAR CONTIENE CUALQUIER ALFA-TOCOFEROL PRESENTE Y DICHA FASE DE DISOLVENTE POLAR CONTIENE DICHOS ADUCTOS DE AMINA Y COMPUESTOS NO-ALFA TOCOFEROLES; SE SEPARAN DICHAS FASES PARA PROPORCIONAR UNA FRACCION DE ALFA-TOCOFEROL NO POLAR Y UNA FRACCION DE ADUCTO DE AMINA Y COMPUESTOS NO ALFA-TOCOFEROLES, POLAR; SE REDUCE DICHO ADUCTO DE AMINA Y COMPUESTOS NO ALFA-TOCOFEROLES PARA FORMAR ALFA-TOCOFEROL; Y SE RECUPERA DICHO ALFA-TOCOFEROL. EL PROCEDIMIENTO ES APLICABLE PARA PRODUCIR D-ALFA-TOCOFEROL A PARTIR DE FUENTES VEGETALES NATURALES.
