고순도 1,4-솔비탄을 이용한 비이온 솔비탄 모노스테아르산 합성

다국어 초록 (Multilingual Abstract)

Nonionic sorbitan monostearate have been successfully prepared by esterification using 1,4-sorbitan and stearic acid. 1,4-sorbitan were prepared using D-sorbitol and acid catalyst at solvent-free conditions. The synthesized surfactants were characterized by NMR and FT-IR. We also investigated the effect of temperature, pressure and catalyst on the synthesis of nonionic sorbitan monostearate. The yields of l,4-sorbitan were 90% at 160℃ under 160 ㎜Hg vacuum, and the yields of nonionic sorbitan monostearate were 92% at 230℃ under 60 ㎜Hg vacuum.
