| Abstract: | Polyether and potassium dihydrogen phosphate were recovered from polyether residue by hot water extraction separation technology. The factors affecting the extraction were studied, such as extraction temperature, crystallization temperature and wash conditions. The results of the industrial tests show that the recovery of polyether is over 75% and the average recovery of potassium dihydrogen phosphate is 70%. The quality of polyether and potassium dihydrogen phosphate produced in industrial preproduction can meet both the first grade of the industrial product standards HG 2321- 92 and the enterprise standards GEP 560S established by the factory. This technology is characterized by high recovery efficiency, simple process, and remarkable economic, environmental and social benefits. |
