Abstract
Hydroxypropionitrile is prepared by hydration of acrylonitrile using strongly basic anion exchange resin as catalyst. The influence of reaction time, temperature, catalyst type, catalyst amount, and AN/H2O ratio (wt) was studied. The optimum conditions: reaction time, 6h; temperature, 50℃; catalyst type, 201×7; resin/AN(wt), 1.5:1; AN/H2O(wt), 1:16. Under the optimized reaction conditions the yield (mol) of 3-hydroxypropionitrile is above 85%. After 12 times of reaction, no obvious decrease in activity of catalyst is observed.
