MANUFACTURE OF WATER-SOLUBLE β-HYDROXYNITRILES |
abstract |
A process for making a water-soluble β-hydroxynitrile. A 1,2-epoxide and an inorganic cyanide salt are reacted in a solvent having aqueous methanol and a buffer therein to form β-hydroxynitrile. The buffer substantially inhibits the information of reaction products other than β-hydroxynitrile. Optionally, water may be removed from the β-hydroxynitrile by azeotropic distillation with acetonitrile and subsequently purified via vacuum distillation and filtraton. |
