| titleOfInvention | The preparation method of 2-fluorine ethylamine hydrochloride |
| abstract | The present invention relates to a kind of preparation method of 2 fluorine ethylamine hydrochlorides, be characterized in, use 2 fluoroethanols to react with the participation of toluene sulfochloride, the nitrogen of routine can be used to get rid of the hydrogen chloride gas in reactant liquor, avoid extraction waits operation, removes the employing of extraction from.Further, optimize the response time of entirety, improve utilization rate of equipment and installations.What is more important, by ethanol and water extraction impurity removing technology, the product content not only obtained is high (99%), and yield improves, and both not only cost of material cheap, be easy to get, pollution-free.Thus, while reducing cost, the output of final thing is significantly increased. |
