| Abstract: | Based on the tailing sodium carbonate decahydrate of ADC foaming agent as raw material,the green process of preparation sodium carbonate hydrate was realized through re-crystallization method.The test results show that the yields of sodium carbonate was increased under the condition of evaporation temperature of 85 ℃, crystallization time of 60min, and two times mother liquor circulation.The technological process has many advantages such as high purity product, simple process flow and convenient operation and so on. |
