Yield:6000-44-8 96.7%

Reaction Conditions:

with sodium hydroxide;Pd-doped copper catalyst on active carbon in water at 160; under 9000.9 Torr;

Steps:

10 g (calculated on the basis of the dry substance) of a Pd-doped copper catalyst on active carbon (Degussa AG, CE 1015 OY/W) suspended in water was placed first analogously to example 1 in an autoclave and 61 g ethanolamine and 272 g sodium hydroxide solution (15% by weight) were added. The autoclave was closed and the contents were heated to 160° C. The pressure was kept at 12 bar (absolute) and the hydrogen that formed was continuously discharged by a pressure control valve. After the end of the reaction (which is evident from the decrease in gas release) it was cooled to 90° C. and the catalyst was removed from the product solution by filtration. 315 g filtrate which contained 29.8 g % by weight Na glycinate was obtained (corresponds to a yield of 96.7% of theory).The filtered catalyst was suspended in 10 g water and fed back into subsequent batches.
