Reaction Conditions:
with Co[PyPS]2Mo11VO40 at 90; for 10 h;Microwave irradiation;Temperature;Reagent/catalyst;
Steps:
1-4; 1-2 A method for producing allantoin for cosmetics is achieved through the following specific steps:
Add 0.1 mol glyoxylic acid solution (mass concentration of 50%) and 0.3 mol urea into the microwave reactor, and then add 2.0g 2 catalyst to it, react the reaction mixture at 90°C for 10 hours, and then filter the catalyst. , After recrystallizing the obtained product, the allantoin product was obtained, and the yield was 89.3%.
