| Use | use as an intermediate in organic synthesis use in organic synthesis. |
| production method | from the reaction of tetrahydrofuran and hydrogen chloride: In the case of boiling of tetrahydrofuran, hydrogen chloride gas was slowly introduced. As the reaction proceeded, the temperature of the reaction solution was gradually increased to above 100 °c. The reaction is complete when the temperature is stable at 103.5-105.5 °c. The fraction of 80-90 °c (1.87kPa) was fractionated under reduced pressure to obtain a crude product. The fraction of 81-82 °c (1.87kPa) was fractionated under reduced pressure to obtain a finished product with a yield of 54%-57%. |
