Abstract

A METHOD FOR PRODUCING AN ?-SULFOFATTY ACID ALKYL ESTER SALT, THE METHOD INCLUDING A SULFONATION STEP IN WHICH A FATTY ACID ALKYL ESTER IS SULFONATED, AN AGING STEP IN WHICH THE SULFONATED PRODUCT OBTAINED IN THE SULFONATION STEP IS AGED, AN ESTERIFICATION STEP IN WHICH THE SULFONATED PRODUCT OBTAINED IN THE AGING STEP IS ESTERIFIED WITH AN ALCOHOL HAVING 1 TO 6 CARBON ATOMS, A NEUTRALIZATION STEP IN WHICH THE ESTERIFIED PRODUCT OBTAINED IN THE ESTERIFICATION STEP IS NEUTRALIZED TO OBTAIN A NEUTRALIZATION PRODUCT, AND A BLEACHING STEP IN WHICH THE NEUTRALIZATION PRODUCT IS BLEACHED TO OBTAIN A BLEACHED PRODUCT, IN WHICH IN THE BLEACHING STEP, THE INITIATION TEMPERATURE OF THE BLEACHING REACTION IS SET AT 55 TO 80�C, AND THE TEMPERATURE IS RAISED FROM THE INITIATION TEMPERATURE TO A MAXIMUM TEMPERATURE OF 85 TO 100�C OVER A PERIOD OF 20 TO 240 MINUTES AFTER THE REACTION INITIATION, KEPT AT THE MAXIMUM TEMPERATURE FOR 20 TO 360 MINUTES, AND THEN LOWERED TO A REACTION TERMINATION TEMPERATURE OF 55 TO 80�C.
