Participants

Reaction Steps

A solution of 19.6 gm (0.2 mol) of D-glucose (containing 0.1 mol of H2O) and 18.2 gm (0.2 mol) of 2,3-dihydroxypropylamine in 400 ml of water and 350 ml of methanol was, after the addition of 18 gm of Raney nickel, hydrogenated for 2 hours at 50° C. in an autoclave having stirring means, and then for 3 hours at 70° C., both at a hydrogen pressure of about 180 kg/cm. After the catalyst had been filtered off and the solvent removed by distillation under reduced pressure, the residue was recrystallized from water/2-propanol and digested with cold 2-propanol. 36.5 gm (72% of theory) of colorless, crystalline N-(2,3-dihydroxypropyl)-glucamine with a melting point of 133° to 134° C. was obtained.
