Process for the preparation of dinitrile of malenic acid |
| abstract |
Production of malononitrile or its derivatives (I) comprises heating an isonitrile (II) at 700-1000 degrees C. Production of compounds of formula (I) comprises heating an isonitrile of formula (II) at 700-1000 degrees C, optionally in the presence of a nitrile of formula (III): R<1> = H, alkyl or cycloalkyl; R<2> = alkyl or cycloalkyl; R<3> = H, alkyl or cycloalkyl. |
