  • Monomeric N-methyleneaminoacetonitrile
    Patent number: 4225504
    Abstract: The novel monomeric compound N-methyleneaminoacetonitrile is produced by reacting glycinonitrile with formaldehyde in the absence of ammonia. The process is conveniently carried out by forming aqueous glycinonitrile in situ using known methods, removing any excess ammonia from the reaction medium and then introducing at least an equimolar amount of formaldehdye. The reaction is allowed to proceed substantially to completion. The novel product has a higher melting point than the previously reported trimer.
