초록

DEAE-chitin은 alkali-chitin 용액에 DEAE·HCl을 이용하여 제조하였다. 제조된 DEAE-chitin 은 물과 유기용매에 대한 향상된 용해성을 나타내었다. DEAE-chitin은 chitin의 탈아세틸화반응보다 온화한 조건인 sodium borohydride를 함유하고 있는 10% 수산화나트륨 수용액으로 80℃에서 9시간동안 탈아세틸화반응을 행하여 DEAE-chitosan을 제조하였고, DEAE-chitin의 양이 온성을 증가시키기 위해 ethyl halide를 이용하여 4차화시킴으로써 4차 암모늄기를 가진 TEAE-chitin유도체를 각각 합성하였다. 이들 합성유도체들의 반응에 따른 구조변화는 FTIR, ¹H NMR 등으로 확인하였고, 카올린 현탁액을 이용한 응집실험결과 pH가 약 알칼리일 때, 그리고 수지농도가 8ppm일 때 최적의 응집성능을 나타냄을 알 수 있었다.

A DEAE-chitin was prepared with DEAE·HCl in an aqueous alkali-chitin solution. The resulting DEAE-chitin exhibited a highly improved affinity to water and organic solvents, It was N-deacetylated by heating in aqueous 10% sodium hydroxide containing sodium borohydride for 9h at 80℃ to produce DEAE-chitosan. These conditions were milder than those for the N-deacetylation of chitin. In order to increase its cationic character, the DEAE-chitin was treated with ethyl halide to give TEAE-chitin. The structural changes in the chitin derivatives were confirmed by using both FT-IR and ¹H NMR, and their flocculating behavior, in kaoline suspension showed the optimum property at a weak alkaline pH and 8 ppm concentration of resin conditions.
