| Abstract | |
We have studied the critical parameters of Micheletti's glycoluril synthesis starting from urea and glyoxal on a statistical and multivariate analysis basis {[}12]. The process is potentially highly useful for scaling-up glycoluril production, and needs to be optimized. We have come to a conclusion that H3PO4 could be used as well as P4O10 giving high yields at temperature around 95 degrees C, using glyoxal without prior purification. All reactions have been completed in less than 25 min with the yield as high as 80% under the optimized conditions. (AU) | |
