| titleOfInvention | Cyanoformamide |
| abstract | Cyanoformamide is made by reacting cyanogen with a monohydric alcohol to form the corresponding cyanoformimino ether which is then reacted with anhydrous hydrogen halide, particularly hydrogen chloride, to form cyanoformamide and the halide corresponding to the alcohol. It is preferred to use boric acid of a Lewis acid, especially aluminium, tin, iron or zinc chloride or boron trifluoride as a catalyst for the ether splitting reaction, which may be conducted in an inert solvent, e.g. an ether, or a chlorinated aliphatic or aromatic hydrocarbon. Allyl alcohol is the particularly preferred member of primary alcohols, which includes alkyl, alkenyl, cycloalkyl, cycloalkenyl, aralkyl or aryl substituted ones, since the allyl halide may be readily hydrolyzed for cyclic re-use in the reaction. In the examples the preparation of cyanoformamide via the methyl, and alkyl ethers are described and the effectiveness of the various ether splitting catalysts is compared. |
