How to determine moisture in acetonitrile and drying methods
1. You can use the Karl Fischer method to determine the moisture content in acetonitrile； 2. It is determined based on the decomposition temperature of acetonitrile; in other words, it depends on whether it is a thermosensitive substance. The laboratory can choose conventional drying methods or vacuum drying methods, with silica gel and phosphorus pentoxide among the possible desiccants ； Industrially, methods such as heat drying, hot air drying, fluidized bed drying, pneumatic drying, and vacuum heat drying can be selected.
We use K to determine the moisture content in acetonitrile. Method F: In our laboratory, anhydrous calcium chloride is usually added to acetonitrile before distillation.
