[求助] 谁配过碱式醋酸锌

求配制碱式醋酸锌的方法?自己20%的醋酸锌75ml+1mol/l氢氧化钠475ml,怎么做不产生沉淀,我师兄说氢氧化钠通氮气,加醋酸锌慢慢溶解,求鉴定,自己准备试试。

银虫 (小有名气)

According to the method described by Auger and Robins) the compound was prepared by slowly distilling powdered anhydrous zinc acetate in a high vacuum. Zinc oxyacetate sublimed gradually and was collected as a crystalline crust on the cool place of the container. After being allowed to cool, the crystalline crust was examined and well-formed single crystals were picked out. They form small (up to 0.8 mm) transparent octahedra, which on prolonged exposure to moist air are hydrolysed and become opaque, while the corresponding beryllium compound is extremely stable. Crystals selected for the present study were octahedra of about 0.6 mm in each dimension and showed no remarkable cleavage.

大意:
根据Auger和Robins描述的方法,通过在高真空中缓慢蒸馏粉末状无水乙酸锌来制备化合物。 逐渐升华的氧乙酸锌在容器的阴凉处收集为结晶壳。 在冷却后,检查结晶外壳并挑出形成良好的单晶。 它们形成小的(最多0.8毫米)透明八面体,长时间暴露在潮湿空气中会水解并变得不透明,而相应的铍化合物非常稳定。选择用于本研究晶体在每个维度约0.6mm八面体并且没有明显的裂痕。
