| Abstract: | The mechanism of formation of α-hydroxymethylserine in the preparation of DL-serine from glycine-Cu2+ and formaldehyde were studied. Conditions for forming serine was determined that n (Cu2 + ): n (glycine): n ( formaldehyde ) =1:100:800,pH 8.5 -9.5,40 min and concentration of DL-serine was 13.67 mg/mL. |
