摘要
以硫酸锌和乙酰水杨酸(ASP)为原料,固液相法制得了乙酰水杨酸锌(C18H14O8Zn·2H2O),用XRD、FT-IR、DSC等对产物进行了表征。X射线粉末衍射数据计算结果表明,所合成的配合物属于单斜晶系,晶胞参数为a=1.1449nm,b=1.4048nm,c=0.9247nm,β=94.46°。合成工艺条件为n(ASP)∶n(Zn2+)=2∶1,pH=6,反应温度80℃,反应时间30min,产率82.5%。
Zinc acetylsalicylate was synthesized by solid-liquid phase reaction with the starting materials of ZnSO4·7H2O and acetylsalicylic acid （ASP）. The product was characterized by X-ray powder diffraction, FT-IR and DSC. The X-ray powder diffraction data indicated that the crystal structure of the complex belonged to monoclinic system. The lattice parameters are α= 1.1449 nm, b = 1.4048 nm, c = 0.9247 nm, β= 94.46°. The optimized conditions for the synthesis are n（ASP） ： n（Zn^2＋） = 2 ： 1, pH = 6, reaction temperature 80℃, and reaction time 30 min, with which the yield of zinc acetylsalicylate is 82.5%.
