- CAS Number:557-11-9
- Molecular formula:C4H8N2O
- Molecular Weight:100.12
Yield: 279 g
Reaction Conditions:
with aluminum oxide;potassium bromide at 90; for 2.16667 h;Temperature;
Steps:
3
5 mol of urea and 3 mol of allyl alcohol were added to the reaction vessel.The 12L mass fraction is 45% potassium bromide solution, 1.5 mol of alumina powder, the stirring speed is controlled at 110 rpm, and the solution temperature is raised to 90 ° C.Maintain 130min, 30kPa vacuum distillation, reduce the solution temperature to 15 ° C, precipitate crystals, wash with a mass fraction of 65% ether solution, mass fraction of 75% dimethylamine solution, recrystallize in 80% methanol solution The anhydrous magnesium sulfate dehydrating agent was dehydrated to obtain 279 g of the finished (prop-2-en-1-yl)urea.
