ABSTRACT:
N,N'-Dicarboxymethyl-1,3-propanediamine (designated PDDA) is prepared by reacting 1,3-propanediamine with formaldehyde and HCN to form hexahydropyrimidine-1,3-diacetonitrile, which is hydrolyzed with an aqueous alkali metal hydroxide to form dialkali metal hexahydropyrimidine-1,3-diacetate which, in turn, is reacted with mineral acid to form the desired PDDA and formaldehyde.
N,n'-dicarboxymethyl-2-hydroxy-1,3-propanediamine (designated HYDROXY-PDDA) is prepared by reacting 1,3-diamino-2-propanol with formaldehyde and HCN to form 5-hydroxyhexahydropyrimidine-1,3-diacetonitrile, which is hydrolyzed with an aqueous alkali metal hydroxide to form dialkali metal 5-hydroxyhexahydropyrimidine-1,3-diacetate which, in turn, is reacted with acid to form the desired HYDROXY-PDDA and formaldehyde.
