초록

염화알루미늄 수용액을 원료로 하여 알루미늄 유기화합물인 aluminum tartrate 합성실험을 수행하였다. 합성시 ethanol/Al solution 혼합비율 및 pH가 합성율에 미치는 영향을 조사하였으며, 합성된 aluminum tartrate는 화학분석, X-선 회절분석, 입도분석 및 SEM 분석을 통하여 시료특성을 평가하였다. 실험결과, ethanol/Al solution 혼합비율 3.0에서 pH 3.0 이상인 경우 aluminum tartrate 합성율은 97% 이상으로 나타났다. 합성반응을 통해 얻은 aluminum tartrate의 각 화학분석결과 $NH_4$ 9.10%, Al 4.83% 및 C 25.8%이었으며, 이의 화학식은 $(NH_4)_3Al(C_4H_4O_6)_3$임을 확인할 수 있었다.

An investigation on the synthesis of aluminum tartrate, one of the aluminum organic compounds, has been performed using aluminum chloride solution as a raw material. For this aim, the effect of the ratio of ethanol/Al solution and pH on the synthesis of aluminum tartrate has been examined and aluminum tartrate synthesized has also been characterized in terms of the chemical composition, X-ray diffraction pattern, particle size distribution, and SEM analysis. As a result, the synthesis more than 97% could be obtained under the conditions of pH more than 3.0 at the ratio of ethanol/Al solution of 3.0. From the chemical analysis of aluminum tartrate synthesized in this work, the content of $NH_4$, Al and C was found to be 9.10, 4.83 and 25.8%, respectively. In addition, aluminum tartrate synthesized from the aluminum chloride solution was found to be $(NH_4)_3Al(C_4H_4O_6)_3$.
