<正> Preparing process was presented and the influences of concentration of acetic acid, reaction temperature, the ratio of cerium carbonate and acetic acid, heat preservation time to the yield of cerium acetate were discussed. The crystalline cerium acetate and rare earth acetate such as (La, Ce, Pr, Nd) (Ac) 3, (Ce, Pr, Nd) (Ac) 3, (Pr, Nd, Er, Y) (Ac)3 and yttrium acetate were prepared under this condition. The shape, structure and composition of the crystals were determined by the methods of SEM, TG-DTA, X-ray diffraction and chemical analysis. The optimum prepared conditions of cerium acetate were described. This prepared process has characteristics such as simple process route, low cost, high yield, good quality, no pollution to environment, etc.
