Paragraph 0020; 0021; 0022; 0023, (2018/07/30)
The invention discloses a synthetic method of 2-aminomalononitrile. The synthetic method comprises the following steps of: 1) adopting aminomalonic acid diethyl ester as a starting material, directlyplacing into 40-60w/v% of ammonium-chloride aqueous solution, reacting for 2-5 hours at a temperature of 100-120 DEG C and preparing to obtain 2-aminopropanediamide; 2) dissolving 2-aminopropanediamide prepared in the step 1) into an organic solvent, heating to rise the temperature, adding solid phosgene, heating and refluxing for 10-12 hours to generate 2-aminomalononitrile. The synthetic methoddisclosed by the invention is simple, pollution-free, safe and environmentally friendly and provides basis for further application of 2-aminomalononitrile.

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.
