摘要： The present invention is a process for preparing aminoacetonitriles or ethylenediamine tetraacetonitrile comprising the steps of (a) admixing glycolonitrile with an amine having at least one primary amine group or ethylenediamine to form an intermediate amine acetonitrile reaction product, (b) admixing the reaction product of Step (a) with formaldehyde and hydrocyanic acid such that each hydrogen on an amine nitrogen is replaced by an acetonitrile group. The resulting aminoacetonitrile advantageously has all amino groups fully substituted with acetonitrile groups.
