Abstract
The purity of industrial 3-methylaminopiperidin dihydrochlorid was determined by TCL volumetric method.The sample was pre-separated via thin-layer chromatography,then digested and distillated in order to measure nitrogen content in the sample.The content of 3-methylaminopiperidin dihydrochlorid was 98.81%,and the relative standard deviation of this method was 0.087%(n=10).This method is simple,rapid and does not need costly instruments,it is also suitable for industrial analysis.
