초록

회분식 추출기를 이용하여 구연산-초산 혼합수용액-n-butylacetate계에서 2급 아민 추출제인 DITDA와 용매화 추출제인 MOHPO를 이용 추출시 물질전달계수에 미치는 교반속도의 영향에 대하여 연구하였다. 실험결과 본 추출장치에서 교반속도가 커질수록 추출도는 증가하였고, 교반속도가 200rpm, 교반시간 30분 정도가 가장 좋은 결과를 얻었다. 또한 구연산-초산 혼합수용액에서 추출제로 2급 아민인 DITBA을 사용했을 경우 추출도가 더 높았다. 물질전달계수는 추출도와 비례함을 알았고, 구연산을 DITDA로 추출시 추잔상측 물질전달계수와 Re수와는 K_r=1.254×10^-3Re^0.536이었다.

The effect of agitation speed on mass transfer coefficient in the extraction of citric acid from mixed aqueous solutions of citric and acetic acid with n-butylacetate solutions of di-isotridecylamine(DITDA) and 50% mixture of tri-n-octyl and try-n-hexyl phosphine oxide(MOHPO), were studied in batch extractor. Experimental results showed that the degree of extraction was higher with increasing agitation speed, and was best at 200rpm and 30 minutes in batch extractor. The higher degree of extraction was obtained in mixed solution of citric-acetic acid by using DITDA than MOHPO as an carrier. Mass transfer coefficient was proportional to the degree of extraction, and K_r=1.254×10^-3Re^0.536 was found for she extraction of citric acid by DITDA.
