| 摘 要： | 考察了羟基磷灰石(HAP)的焙烧条件对乙酸酐与苯酚酯化合成乙酸苯酯反应的影响,并采用X-射线粉末衍射、N2吸附和扫描电镜对催化剂进行了表征。结果表明,焙烧条件通过影响HAP晶格中OH-的脱除和晶体结构的稳定性来改变表面的碱性,进而影响催化活性。最佳焙烧条件为:焙烧温度900℃、焙烧时间4h,在此条件下,乙酸苯酯收率达95.5%。

| Abstract: | The effect of calcinations conditions of hydroxyapatite(HAP)on the esterification of acetic anhydride and phenol to phenyl acetate was investigated, and the HAP catalysts were characterized by X-ray diffraction,N2 adsorption,and scanning electron microcopy.The remove of OH-in the crystal lattice and the stability of HAP,which were controlled by calcinations conditions,resulted in the change of the basic capacity on its surface,further affecting the catalytic activity. The proper calcinations conditions were... |
