摘要:
This invention relates to a process for the catalytic hydrolysis of an .alpha.-aminonitrile in the heterogeneous phase, and to polymeric resins having a catalytic activity for carrying out the present process.The process according to this invention is characterized in that said .alpha.-aminonitrile or one of the salts thereof is reacted in an aqueous medium, in the heterogeneous phase and in the presence of hydroxide ions on a polymeric resin which contains side chains carrying a carbonyl group, and which is insoluble in the aqueous basic medium.
摘要:
The device for carrying out the continuous process for synthesizing an .alpha.-amino acid incorporates: (a) a vessel (10) for feeding .alpha.-amino-nitrile, or one of its salts; (b) a connecting pipe (12), in which a pump (14) is mounted, connecting the feed vessel (10) to (c) a catalysis column (16) containing a carbonyl-containing polymeric resin (18) which is insoluble in basic aqueous medium; (d) a connecting pipe (20) from the catalysis column (16) to (e) a hydrolysis reactor (22), acting simultaneously as a reservoir for the .alpha.-amino acid salt formed, and equipped with (f) means for feeding hydroxide ions, comprising a feed vessel (24), a pipe (26) and a pump (28); and (g) a pipe (30) for drawing off the .alpha.-amino acid salt formed.
摘要:
A process for the chemical catalytic hydrolysis of an .alpha.-aminonitrile or of one of the salts thereof, characterized in that an aqueous solution containing at least one carbonyl derivative is reacted with the said .alpha.-amine nitrile or with one of the salts thereof in the presence of hydroxide ions.
