HOW TO ELIMINATE THE OBSTRUCTION OF SODIUM CARBONATE IN THE COURSE OF DETER MINATION OF THE CONTENT OF SODIUM BORATES
Liu Yinghua
In order to eliminate the obstruction of Sodium Carbonate in the course of determination of the content of Sodium Borates,is,used,the,method of optimizati: n through experiments and are studied the choice and control of fhe condtions of the experiments. Our conclusion is:1) Add hydrochloric tacid to decom pose Sodium Carbonate,then add Polyatomic alchohol,after the tormation of the complex acid,heating is done to eliminate Carbon Dioxide; 2)Use Glycerine as complexing agent,after 20 minutes of heating with theemperature controlled between 130°C-138°C,the accurate result can beoptained.
