61	N,N'-diacetic acid-N'-cyanomethyl, salts thereof, and their preparation	US806032	1991-12-21	US5177243A	1993-01-05	Brian A. Parker
A novel intermediate useful in the synthesis of ethylenediaminetriacetic acid (ED3A) or its salts. A salt of N,N'-ethylenediaminediacetic acid (ED2AH.sub.2) is condensed with formaldehyde to form a stable 5-membered ring intermediate. The addition of cyanide across this cyclic material forms ethylenediamine N,N'-diacetic acid-N'-cyanomethyl or salts thereof (mononitrile-diacid), which is useful intermediate in the production of ED3A. The nitrile in aqueous solutions may be spontaneously cyclized to form 2-oxo-1,4-piperazindeiacetic acid (3KP) or salts thereof. In the presence of excess base, salts of ED3A are formed in excellent yield and purity.

This invention relates to the production of aminoacetonitriles, and more specifically to an integrated process wherein a crude, unpurified reactor product stream from a hydrogen cyanide reactor together with a formaldehyde stream, optionally, a crude, unpurified reactor product stream from a formaldehyde process reactor are fed directly to a reactive absorber with an additional nitrogen source and scrubbed with a controlled pH aqueous solution to produce aminoacetonitriles in high yields. This process eliminates intermediate recovery and purification processes associated with conventional hydrogen cyanide and formaldehyde production processes by integrating the recovery and reaction processes into a reactive absorber.

This invention relates to the production of iminodiacetonitrile, and more specifically to an integrated process wherein a crude, unpurified reactor gas stream from a hydrogen cyanide reactor and optionally, a crude, unpurified reactor gas stream from a formaldehyde process reactor are fed directly to a reactive absorber together with additional ammonia and acidified water to produce iminodiacetonitrile in high yields. This process provides improved economics for producing iminodiacetonitrile by eliminating costly intermediate recovery and purification processes associated with conventional hydrogen cyanide and formaldehyde production processes.

This invention relates to two processes for preparing aminoacetonitriles in one vessel under anhydrous conditions. Process I involves the steps of: (A) reacting trimethylsilyl cyanide and an aldehyde in a water miscible amide solvent to obtain a silyl blocked cyanohydrin solution; (B) adding a catalytic amount of water to the silyl blocked cyanohydrin solution from Step (A); and (C) passing ammonia through the solution to obtain an aminoacetonitrile. Process II involves the steps of: (A') reacting trimethylsilyl cyanide with an aldehyde in the absence of solvent to form a silyl blocked cyanohydrin; (B') adding a water miscible amide solvent to the silyl blocked cyanohydrin from Step (A') to obtain a solution; and (C') passing ammonia through the solution to obtain an aminoacetonitrile. Aminoacetonitriles are important intermediates in the preparation of amino acids, thiadiazoles, acylaminoacetonitriles, and imidazole derivatives.
