Detergency Performance of Sodium Monoglycerol α-Sulfonated Alkanonates

소디움알파술폰 고급지방산 모노글리세리드의 세정성

The detergencies of these new functional anionic surfactants, sodium monoglycerol ${\alpha}$-sulfonated alkanoates, were investigated and compared with those of two commercial surfactants, that is, sodium ${\alpha}$-sulfonated alkanoic acid methyl ester and sodium alkyl benzene sulfonate. According to the variation of the hydrophobic alkyl chain length, the order of detergency was shown to be $C_{16}$>$C_{18}$>$C_{14}$>$C_{12}$. From the comparision experiment for the detergency and the various fundamental properties of two other surfactants, it was found that sodium monoglycerol ${\alpha}$-sulfonated hexadecanonate has the most outstanding characteristics of detergency. Possibly this result shows light on its industrial application as a nonpolluting detergent.

새로운 기능성을 갖는 sodium monoglycerol ${\alpha}$-sulfonated alkanonate류에서 소수성 부분의 알킬기의 탄소수에 따른 세정력을 비교한 결과 $C_{16}$>$C_{18}$>$C_{14}$>$C_{12}$의 순으로 나타났고, 이들 중 세정력이 가장 우수한 sodium monoglycerol ${\alpha}$-sulfonated hexadecanonate는 무공해 세정제로서 기대성이 있는바 현재 공업적으로 대량 사용하고 있는 sodium ${\alpha}$-sulfonated alkanoic acid methyl ester와 sodium alkyl benzene sulfonate를 상대 비교한 결과, 보다 우수한 세정력을 나타내며 공업적 응용성에 기대성이 크다.
