| titleOfInvention | A kind of preparation method of tetrahydrofuran copolyether |
| abstract | The invention relates to a method for preparing tetrahydrofuran copolyether. The preparation method is (1) premixing ε-caprolactone and tetrahydrofuran (2) using tetrahydrofuran, 1,4 butanediol, ε-caprolactone, and water in hetero Preparation of tetrahydrofuran copolyether under the catalysis of polyacid (3) Extraction and purification of tetrahydrofuran copolyether; using phosphotungstic acid as heteropolyacid catalyst, the corrosion of equipment is extremely low; a kind of performance that can be used to prepare polyurethane elastomer is more superior The tetrahydrofuran copolyether material, under the premise that the molecular weight of the target product is 2000, the reaction yield can reach 25%, and the reaction selectivity can reach more than 97%. |
