| 中文摘要: |
| 研究采用管式反应器连续化合成促进剂ZDMC（二甲基二硫代氨基甲酸锌）的工艺，并分析工艺参数对产品质量的影响。最佳工艺条件为：n（二甲胺）∶n（二硫化碳）∶n（氢氧化钠）∶n（氯化锌）＝1.0∶1.3∶1.01∶0.502，二甲胺质量分数为40%，氢氧化钠质量分数为32%，氯化锌质量分数为15%，反应温度为40 ℃，水、二甲胺、二硫化碳、氢氧化钠、氯化锌体积比为7∶25∶10∶15∶75；采用该工艺条件，在管式反应器中进行连续化合成反应，所得产品质量满足GB/T 11409—2008要求，收率在98.5%以上。 |
| 英文摘要: |
| The synthesis process of accelerator ZDMC（zinc dimethyldithiocarbamate） using a continuous tubular reactor was studied，and the influence of process parameters on product quality was analyzed.The optimal process conditions were n（dimethylamine）∶n（carbon disulfide）∶n（sodium hydroxide）∶n（zinc chloride）＝1.0∶1.3∶1.01∶0.502，the mass fraction of dimethylamine，sodium hydroxide and zinc chloride was 40%，32%，15% respectively，the reaction temperature was 40 ℃，and the volume ratio of water，dimethylamine，carbon disulfide，sodium hydroxide and zinc chloride was 7∶25∶10∶15∶75.Using this process condition，a continuous synthesis reaction was carried out in a tubular reactor，and the product quality met the requirements of GB/T 11409—2008 with a yield of over 98.5%. |
