The research on the solubility of decabromodiphenyl ether based on recycling of waste electronic plastic by solvent process

摘要

The accurate solid solubility data are a key to the design of process and the selection of operating conditions for separating PBDEs from waste electric plastic by solvent. The solubility of DecaBDE in different system was determined by using the isothermal dissolved method, and the impact law of temperature and solvent composition on the solubility of DecaBDE were discussed, the experimental solubility data was correlated with Apelblat equation equation. The results showed that the solubility of DecaBDE was mainly affected by the temperature and the solvent composition, and that Apelblat equation was suitable to fit the experimental results, the deviation was very small.
