Hydroxylamine hydrochloride (50.0 g) and obtained
potassium acetate (108.0 g) were dissolved in 30 mL
water and 60 mL dioxane. The solution was stirred
vigorously. Then tri-associated phosgene (85.4 g)
dissolved in 600 mL dioxane solution was added
dropwise to the previous solution at 0 °C. The solution
was continuously stirred for half an hour, then
acidified with concentrated hydrochloric acid to pH
approximately 2–3, and subsequently evaporated at
reduced pressure with the temperature not higher than
60 °C. The residue was extracted with alcohol for
desalting, and the solid was obtained by evaporating the
alcohol solution. DHU crystals with a needle form were

盐酸羟胺50.0克与已制备的醋酸钾108.0克溶于30毫升水和60毫升二氧六环的混合液中，剧烈搅拌，冷却到0 °C，并在0 °C下滴加85.4克三聚光气在600毫升二氧六环中的溶液，滴加完后继续搅拌半小时，然后用浓盐酸酸化到pH约为2-3，减压蒸馏（温度不能超过60°C）除去溶剂，剩余物用适量乙醇溶解以除盐，然后蒸馏该乙醇溶液得到产物固体，用二氧六环对产物进行重结晶可以得到针状的DHU晶体。
楼主，做这种实验要小心，要严格控制温度，滴加不要太快。。。
