| Abstract: | α-Trifluoromethyl ethylamine was prepared under pressure by using L-alanine and sulfur tetrafluoride as raw materials for one step fluoridation reaction.The optimal operating conditions for the process were investigated experimentally.These conditions obtained are： 100 g of L-alanine as raw material and molecular ratio of sulfur tetrafluoride to L-alanine at 2,the reaction at temperature of 55 ℃ and pressure of 18～19 kgf/cm^2 for 12 h.The yield of the product is above 55 % and the melting point of the hydrochloric salt of the product is above 218.5 ℃. |
