This study presents a green and efficient process for the preparation of tetraalkylammonium azide applicable in large scale under mild conditions. Moreover, the purity of the product and the reaction yield were significantly high. In this regard, two reactors are compared: batch and flow column reactor. Results demonstrated the greater efficiency of the flow column reactor. Strong base anion exchange resin was used as catalyst. The reusability of the resin was excellent. The environmental factor of this process is 0.85, which is excellent for a chemical process in industrial scale. Accordingly, this method involved almost all principles of Green Chemistry, which is unique for its type.

一种绿色环保的制备具有优异环境因子的叠氮化四烷基铵的方法：间歇式和流式塔式反应器的比较

这项研究提出了一种绿色高效的制备四烷基叠氮化铵的方法，该方法可在温和条件下大规模使用。而且，产物的纯度和反应产率都很高。在这方面，比较了两个反应器：间歇式和流动塔式反应器。结果表明，流动塔反应器具有更高的效率。强碱阴离子交换树脂用作催化剂。树脂的可重复使用性极好。该过程的环境因子为0.85，对于工业规模的化学过程而言是极好的。因此，该方法涉及绿色化学的几乎所有原理，这是该类型所独有的。
