摘　　要：外循环喷雾式反应器是目前最先进的乙氧基化反应器之一,但反应釜式(含外循环式)反应器仍是中小型企业的主流,如何设计出最适合企业及产品的工艺参数是关键。通过对比釜式与外循环釜式反应器在环氧乙烷(丙烷)实际加成制备非离子表面活性剂过程中的效率、产品质量、安全性,得出带外循环器的反应釜更适合企业发展的结论,而针对不同产品选择不同的工艺步骤及智能化是今后发展的方向。The external loop spray reactor is one of the most advanced ethoxylation reactors,but the kettle type reactor(including the external circulation type)is still the mainstream of small and medium-sized enterprises,how to design the most suitable process parameters for enterprises and products is the key.In this paper,the efficiencies,product qualities and safeties of the kettle type reactor and the external loop reactor in the preparation of non-ionic surfactant from epoxy ethane or epoxy propane were compared.It was pointed out that the external loop reactor is more suitable,and choosing different process and intelligentization for different products is the direction of future development.
