Abstract

${\alpha}$-sulfonated fatty acid methyl esters[$C_mH_{2m+1}CH(SO_3Na)COOC_nH_{2n+1}$], where hydrophobic group has carbon number of 12~18, were prepard by sulfonation of fatty acid methylester. The mole ratio of $SO_3$ to ester used was 1.3 and the reaction temperature was $70{\sim}90^{\circ}C$. The yield was found to be 97% by mixed gas reaction of inactive gas/gaseous $SO_3$. Studies on bleaching and neutralization processes in the pilot scale provided conditions applicable to industrial synthesis process.
