以苯为反应介质和脱水剂，首次采用一步苯-水共沸法制备了NaFeSO4F和NaFeSO4F·2H2O，从FeSO4·7H2O和NaF开始，在200℃的低温条件下，在短时间内（1 min）用不同密封帽的高压釜选择性制备NaFeSO4F·2H2O。
A one-step benzene–water azeotrope method has been carried out for the first time for the selective preparation of NaFeSO4F and NaFeSO4F·2H2O starting from FeSO4·7H2O and NaF in a short time (1 min) at a low temperature (200 °C) in an autoclave with different sealed caps using benzene as a reaction medium and dehydrant.
