THORIUM CHLORIDE制备
制法1 Th+6NH4Cl＝(NH4)2ThCl6+4NH3+2H2
(NH4)2ThCl6＝ThCl4+2NH4Cl
粉末状钍金属是很容易得到的，将其与六倍摩尔量的NH4Cl在一干燥箱中混合，然后装入Pyrex玻璃管中，再将管的颈部拉成毛细尖嘴。加热试管至300℃，反应大约30h以后，定量生成三元氯化物(NH4)2ThCl6，接着在真空［约1.3×10-1Pa(10-3Torr）］下350℃分解此化合物得到纯的几乎无色的细粉状ThCl4。
制法2 将草酸钍置于石英舟中，将石英舟放入玻璃反应管中，通入二氧化碳和四氯化碳的1∶1混合气(将四氯化碳放入支管蒸馏烧瓶中，在水浴中加热至57℃。开启二氧化碳钢瓶，鼓泡通过四氯化碳，经垂熔玻璃板滤出。混合气通过镍线圈加热至57℃以上，再导入玻璃反应管中。流速50～200cm3/min，四氯化碳的消耗量约为60g/h)，同时加热至200℃，并保持该温度2h，然后升温至425℃加热4h，再升温至510℃保持1h，最后在610℃时保持1h，即制得氯化钍产品。收率为99.4%。
