乙酸钠(127-09-3)的制备方法：    由乙酸钙与碳酸钠进行复分解反应而得。反应后经过滤、蒸发、结晶、干燥、脱水得到产品。也可以从生产糠醛、合成樟脑以及其他产品的副产物中回收乙酸钠。试剂纯品也用工业品精制，也可用醋酸与碱中和制得。质量标准：国家标准(优级纯)指标名称                                      指标含量/%                                      ≥99.0水溶液反应                                    合格澄清度试验                                    合格水不溶物/%                                 ≤0.005灼烧失重/%                                   ≤0.5氯化物(Cl)/%                               ≤0.002硫酸盐(SO4)/%                              ≤0.005磷酸盐(PO4)/%                             ≤0.0005镁(Mg)/%                                  ≤0.0005铝(Al)/%                                   ≤0.001钙(Ca)/%                                   ≤0.005铁(Fe)/%                                  ≤0.0005重金属(以Ag计)/%                           ≤0.001 包装及贮运：    工业品用编织袋或桶装，试剂品用玻璃瓶或塑料瓶包装，密封贮存。
