    摘要: A method of manufacturing N-alkyl-N'-methyl-alkyleneureas, by reacting an alkyleneurea with formaldehyde to produce a hydroxymethyl-alkyleneurea, and further reacting said hydroxymethyl-alkyleneurea with formic acid to yield a N-alkyl-N'-methyl-alkyleneurea product, wherein the molar ratio of the N-alkyl-N'-hydroxymethyl-alkyleneureas or N,N'-(bis)hydroxymethyl-alkyleneureas is from 1-2 to 1-10, preferably 1-4 to 1-7.
