摘要: Abstract The concentration-time relationships of the individual active species in oligocondensation stage reaction melamine with formaldehyde have been investigated, mainly by electrochemical methods. Based on equations, a kinetic model overall was established and rate constants were calculated numerical results suggest hydroxy-methylamines are converted to methylene dimethylene ether bridged compounds acid- base-catalyzed reactions, respectively. At pH 7-10 formation bridges scission may occur.
