Abstract: Zincum maleopimarate (MPAZn) has been synthesized from maleopimaric acid and zinc acetate with solvent method. The influence of reaction conditions such as amount of raw material, reaction time, reaction temperature on product were discussed respectively. Zinc content in the products was determined by complexometric titration. The target product was analyzed and characterized by Fourier transform infrared spectrometer (FT-IR), Scanning electron microscope (SEM), Energy dispersive X-ray microanalysis (EDAX) analysis and X-ray diffraction (XRD). The optimum reaction conditions were ascertained as follows: n(zinc acetate):n(maleopimaric acid)=3:1,at 328K for 5h,the yield of MPAZn could reach 94%. It was found that MPAZn was three-dimensional reticulation compound and chemical bonding occurs between the —COO- and Zn2+.
