Abstract: A large-scale industrial process for the production of aminocyanoacetamide is disclosed. A starting material is cyanoacetic acid ester, which is treated with a nitrous acid in a first step to a corresponding hydroxy-iminocyanoacetic acid ester. The hydroxy-iminocyanoacetic acid ester is then hydrogenated and, in a following step, treated with ammonia for obtaining the final product aminocyanoacetamide.
