Abstract
PROCEDIMIENTO DE SULFONACION DE ESTERES DE ACIDOS GRASOS, QUE PERMITE OBTENER SULFONATOS DE ESTERES CON UN BAJO CONTENIDO EN SULFONATOS DE ACIDOS GRASOS. LOS ESTERES C1-C4 DE ACIDOS GRASOS C8-C22, SE SULFONAN CON TRIOXIDO DE AZUFRE MEZCLADO CON UN GAS INERTE, EN UNA RELACION MOLAR DE 1-1 A 2,5-1 DE SO3/ESTER, A TEMPERATURAS DE 0-150JC, PREFERENTEMENTE DE 30-130JC; LA MEZCLA OBTENIDA SE SOMETE A UN PROCESO DE ENVEJECIMIENTO, EN EL QUE LA SULFONACION DEL ESTER SE COMPLETA Y EL ACIDO SULFONICO RESULTANTE SE NEUTRALIZA SEGUIDAMENTE. ANTES DEL FINAL DE LA ETAPA DE ENVEJECIMIENTO SE AÑADE UN ALCOHOL C1-C4 A LA MEZCLA DE ACIDOS SULFONICOS, EN UN 25% MOLAR DEL EXCESO DE TRIOXIDO DE AZUFRE SOBRE LA ESTEQUIOMETRIA SO3:ESTER 1:1, CON LO QUE SE REDUCE EL CONTENIDO EN SULFONATOS DE ACIDOS GRASOS DEL PRODUCTO. LOS SULFONATOS SE EMPLEAN COMO DETERGENTES.
