| titleOfInvention | Method for producing malononitrile |
| abstract | (57) [Summary] Cyanoacetamide and PO in batch method Provides another effective method for the synthesis of malononitrile from the reaction of Cl 3. SOLUTION: In the method for producing malononitrile, characterized in that a porous granular solid substance is used as an adsorbent, a method for preparing a malononitrile in a solvent in the presence of an organic N donor base as a catalyst and a porous particulate solid substance as an adsorbent , POCl 3 as a dehydrating agent with cyanoacetamide, 80-120 ° C. At 8 ° C. for 6 to 8 hours and distilling the product from the crude product under vacuum in the presence of a stabilizer into a receiver containing the same stabilizer to give the desired product of high purity and long shelf life Including obtaining. |
