WebEthanolic solution of potassium cyanide (KCN in ethanol) is heated under reflux with the halogenoalkane; The product is a nitrile. For example, bromoethane reacts with ethanolic potassium cyanide when heated under reflux to form propanenitrile . The halogen is replaced by a cyanide group, CN- WebReactions. If a halogenoalkane is heated under reflux with a solution of sodium or potassium cyanide in ethanol, the halogen is replaced by a -CN group and a nitrile is produced. Heating under reflux means heating with a condenser placed vertically in the flask to prevent loss of volatile substances from the mixture. The solvent is important.
