Reaction Steps

Melamine and glyoxylic acid are dissolved in dimethylsulfoxide and heated to 50°-80° C. for 5-8 hours. The solvent is removed and replaced by methanol. Sulfuric acid is added as a catalyst and the mixture heated to reflux for 5-10 hours, at which the solution is dried with a drying agent, i.e., 3A molecular sieve. The catalyst is neutralized with base and the methanol removed. The remaining mixture is filtered to yield methyl melamine glycolate methyl ether.
