---|---|---|
98% | With thionyl chloride; In N-methyl-acetamide; water; benzene; | EXAMPLE 7 A mixture of 975 g. of <strong>[2002-24-6]monoethanolamine hydrochloride</strong>, 3.7 g. of dimethylformamide and 3500 g. of benzene was heated to 75 to 80C., and 1404 g. of thionylchloride were added dropwise thereto over 7 hours at the same temperature. After the addition was completed, the reaction solution was kept at the same temperature for further 1 hour and cooled to 30C., and then 2900 g. of water was added thereto. Then the solution was allowed to stand to separate into the benzene and aqueous layers. 4150 g. of the aqueous layer thus obtained contained 2-chloroethylamine hydrochloride which was produced in 98 % of yield, and 2.7 % by weight of free sulfur dioxide based on the aqueous layer. |
95% | With thionyl chloride; In toluene; at 75℃; for 3h; | Reagents and reaction conditions: SOCl2, Toluene, 75 Necked flask was added 15.0g of ethanolamine hydrochloride M-07 and toluene 15mL, stirring in an oil bath heated to 75 , the pressure-equalizing dropping funnel was slowly added dropwise 20.0g of thionyl chloride, the reaction ends after 3h. Cooling to room temperature, suction filtered, the filter cake was washed with a small amount of toluene and the toluene filtrate recovery next reuse. The filter cake was dried in vacuo to give a white solid 2-chloro-ethylamine hydrochloride 16.9g, that is, M-08, 95% yield. |
