Abstract

Cellulose was reacted with ethylene oxide to get hydroxyethylcellulose. Quaternary ammonium salt was produced by reaction of epichlorohydrin and trialkylamine. The epoxide ring was opened by acid addition to 3-chloro-2-hydroxypropyltrialkylammonium chloride. Previously unreported two compounds, hydroxyethylcellulose-2-hydroxypropylammonium chloride ether and hydroxyethylcellulose-2-hydroxypropyltriethylammonium chloride ether were synthesized by substitution reaction of hydroxyethylcellulose with glycidyltrialkylammonium chloride or 3-chloro-2-hydroxypropyl-glycidyltrialkylammonium trialkylammonium chloride. All of the compounds including starting materials and reaction intermediates were characterized by $^1H$-NMR and FT-IR spectroscopy.

Cellulose를 출발물질로 하여 ethylene oxide와 hydroxyethylcellulose를 합성하였다. Epichlorohydrin과 triakylamine을 치환반응시켜 제4급 암모늄염을 만든후, 산을 첨가하여 3-chloro-2-hydroxypropyltrialkylammonium chloride를 얻었다. Hydroxyethylcellulose와 glycidylalkylammonium chloride 또는 3-chloro-2-hydroxypropyltrialkylammonium chloride를 coupling하여 지금까지 알려져 있지 않은 화합물 hydroxyethylcellulose-2-hydroxypropylammonium chloride ether와 hydroxyethyl-cellulose-2-hydroxypropyltriethylammonium chloride ether를 각각 73.9%, 74.2%의 수율로 합성하였다.
