二氯二氧化铬合成路线

二氯二氧化铬上下游产品

二氯二氧化铬制备

1.将150g三氧化铬溶于100mL水中,加入330mL浓盐酸,用冷冻剂冷却至0℃。在搅拌下滴入450mL浓硫酸。此时,溶液的温度应保持在10℃以下。反应结束后,将溶液注入分液漏斗中,分出下层部分的溶液并储存于密闭容器中,收率189g(81%)。

安装精馏装置并将上述溶液进行分馏,收集115~116℃(0.9796×105Pa)的馏分(为粗制品的65%)。保存时,应通入干燥空气以完全逐出氯化氢,然后进行蒸馏并封入安瓿中,置暗处储存。

因生成物侵蚀磨口的润滑脂,造成润滑脂固化使磨口处活动受阻,所以宜采用聚四氟乙烯一类的无润滑脂的磨口。
