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 $(NH_4)_3Al(C_4H_4O_6)_3$.
