Yield:5835-28-9 97%

Reaction Conditions:

with palladium 10% on activated carbon in water at 40; for 24 h;Temperature;Solvent;

Steps:

1.1
1) Add 2000 mL of water to a single-mouth bottle with a stirrer,Glyoxylic acid 149g (2mol),Ethanolamine 122g (2mol),Palladium carbon composite (8g),Wherein the palladium carbon composite material has a mass fraction of palladium of 10%;After mixing and mixing,Heated to 40 ° C,Atmospheric hydrogenation reduction reaction for 24h,After the reaction is over,Cool to room temperature;filter,The filter residue is a palladium carbon composite material.The filtrate was concentrated to dryness.Then recrystallized from ethanol to give N-(2-hydroxyethyl)glycine (230 g);The yield was 97%.
