烟酸与氧化锌或碱式碳酸锌的机械化学反应

用行星式球磨机或振荡式球磨机作为机械能发生装置，水(50 μL)或DMF(50 μL)或甲醇(150 μL)作为球磨过程中滴加的辅助溶剂，分别研究了烟酸（HNA）和氧化锌、烟酸和碱式碳酸锌的机械化学反应。 结果表明，当上述的2个化学反应在行星式球磨机(45 Hz)或在振荡式球磨机(20 Hz)中球磨30 min，少量水或者DMF均可以促使生成零维的四水合二烟酸锌（Ⅱ）：[Zn(NA)2(H2O)4]。 在行星式球磨机中球磨烟酸、氧化锌和少量水的混合物，在15 Hz条件下球磨30 min，只产生少量目标产物，当球磨时间延长为60 min可生成大量目标产物，而且达到反应平衡。

Mechanochemical Reactions Between Nicotinic Acid and Zinc Oxide,or Basic Zinc Carbonate

In a planetary or a shaking ball milling machine, when H2O(50 μL) or DMF(50 μL) or methanol(150 μL) were added as assisting liquids in ball milling processes, the mechanochemical reactions between nicotinic acid and zinc oxide or basic zinc carbonate have been studied. The results show that ball milling the starting materials in the presence of H2O or DMF in the planetary(at 45 Hz) or shaking(at 20 Hz) ball milling machine, a zero-dimensional coordination compound, [Zn(NA)2(H2O)4] could be obtained after 30 min reactions. With the absence of DMF and methanol, the target compound could not be synthesized in a planetary ball milling process at lower frequency of 15 Hz. However, the similar reaction could be initiated once prolonging the reaction time to 60 min under similar conditions.
