Abstract

본 발명은 알파 술포지방산 에스테르염을 표백하는 방법을 제공하며, 이 방법은 알파 술포 지방산 에스테르를 알칼리 금속 수산화물로 중화하여 얻은 하기 일반식(Ⅲ)의 알파 술포 지방산 에스테르 100중량부에 대하여 과산화수소와 차아염소산의 알칼리금속염의 혼합물 0.1내지 10중량부, 그리고 하기 일반식(Ⅰ)로 표기되는 알칼리금속 규산염 수용액 0.1 내지 10중량부의 혼합물로 처리함을 특징으로 한다.The present invention provides a method for bleaching an alpha sulfofatty acid ester salt, the method comprising hydrogen peroxide and hypoxia with respect to 100 parts by weight of an alpha sulfo fatty acid ester of formula (III) obtained by neutralizing the alpha sulfo fatty acid ester with an alkali metal hydroxide. 0.1 to 10 parts by weight of a mixture of alkali metal salts of chloric acid, and 0.1 to 10 parts by weight of an alkali metal silicate aqueous solution represented by the following general formula (I).

(상기 식중, R은 C8∼C22알킬기 R1은 H 또는 C1∼C4알킬기 R2는 C1∼C4알킬기이고, M은 수용성 염을 형성하는 알칼리 금속을 의미한다.)(Wherein R is a C 8 -C 22 alkyl group R 1 is H or a C 1 -C 4 alkyl group R 2 is a C 1 -C 4 alkyl group, and M means an alkali metal forming a water-soluble salt.)

상기한 본 발명의 방법에 의하면, 상품화하기에 적합한 색상을 갖고 이중염의 함량이 낮은 알파 술포지방산 에스테르염을 얻을 수 있다.According to the method of the present invention described above, an alpha sulfofatty acid ester salt having a color suitable for commercialization and a low content of a double salt can be obtained.
