3-Hydroxypropionitrile synthesis

12synthesis methods
3-Hydroxypropionitrile can be prepared by reacting ethylene chlorohydrin with sodium cyanide (Kendall and McKenzie 1923; Britton et al 1941; Fukui et al 1961), by reacting ethylene oxide and hydrogen cyanide in an alkaline medium (Badische Anilin and Soda-Fabrik 1966), or by treating an aqueous solution containing 2.5 vol% acrylonitrile with an alkali catalyst (Howsmon 1962).

Yield:109-78-4 97.3%

Reaction Conditions:

with aluminum oxide;boron trifluoride diethyl etherate in propylene glycol at -10 - 10; for 28 h;Reagent/catalyst;Temperature;

Steps:

7 Example 7
2.70 g of hydrogen cyanide and 4.40 g of ethylene oxide were charged into a closed reactor equipped with a cooling device,Stir; then add 1.0g white solid in Example 5, the reaction was stirred at -10 4h,The reaction was stirred at 10 ° C for another 24h. After the reaction is completed, a small amount of sodium hypochlorite is not involved in the reaction of cyanideHydrogen after the detection of 3-hydroxy-propionitrile content. The results show that under this condition,The yield of 3-hydroxypropionitrile was as high as 97.3%.
