| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | for organic synthesis. |
| production method | 234g(3.2mol) diethylamine is dissolved in 500ml of ether, stirred at 5 ℃, 55g(0.4mol) phosphorus trichloride and 150ml of ether solution are slowly added within 2h, and the mixture is stirred and heated for 4h. Cool to room temperature, filter out diethylamine hydrochloride, and distill the filtrate under reduced pressure. The 120-122 ℃(1.33kPa) fraction was collected to obtain the finished product with 68% yield. |
