PROCESS FOR PREPARING AMINOMALONIC ACID DINITRILE TOSYLAT OR ACETYLAMINOMALONIC ACID DINITRIL |
摘要 |
Process for the production of aminomalonic acid dinitrile from a malonic acid dinitrile compound, such as oximinomalonic acid dinitrile or phenylazomalonic acid dinitrile. The reaction is carried out at an elevated hydrogen pressure in the presence of Raney catalysts and a solvent. When tetrahydrofurane is used as a solvent, the reaction product is precipitated with p-toluene sulfonic acid. When acetic anhydride is used as solvent, the reaction product is precipitated as acetyl aminomalonic acid dinitrile. |
