Application

二氯甲烷可用于气相色谱法(GC)定量检测草食性动物(舞毒蛾)诱导的蓝莓挥发物。
二氯甲烷可用作使用二吡啶-氧化铬(VI)氧化伯醇和仲醇的溶剂。悬浮于DCM中的高氯酸锂是醛与甲硅烷基乙烯酮缩醛进行Mukaiyama醇醛缩合反应的有效介质。DCM也可用作通过锂-溴交换反应由2,6-二溴吡啶合成2-溴-6-硫代吡啶的溶剂。

General description

二氯甲烷是一种氯化有机溶剂,易随时间降解。添加戊烯作为稳定剂可抑制其降解。
对二氯甲烷作为二吡啶-氧化铬(VI)的溶剂介质进行了测试。据报道,溶解度为12.5 g/100 ml。研究了活性炭载体上TiO2负载量对二氯甲烷光分解的作用。
