Reaction Steps

The regenerated catalyst precursor was transferred under CO:H2 pressure, into the autoclave at 95° C. containing CO:H2 (95:5) at 900 psi (6,210 kPa), acetamide (VII) (59.0 g, 1.0 mole), 95% paraformaldehyde (68.0 g, 2,16 mole), water (64.5 g, 3.60 mole) and DME (600 mL). A CO:H2 atmosphere (95:5) at 2200 psi (15,170 kPa) was immediately established. This mixture was heated to 125° C. and was maintained at this temperature for one hour. HPLC analysis of this stream gave a 95% yield of (XVI), 4% (XIV), 7.0% (XVIII), and 0.1% N-methyliminodiacetic acid.
