| Abstract: | It was a traditional experiment to prepare sodium hyposulfite with sodium sulfite and sodium sulfide,sodium carbonate under room temperature.But the experiment had many shortcomings: sodium sulfite is easy to agglomerate in the process of experiment,to bring about inverted siphon,long reaction time,low production rate.In this article,the experimental installation was improved as the experimental condition was optimized on massive experimental foundation.Problems solved,the experiment effect was obviously improved. |
