Kinetics of Hydroxymethylation of Melamine with Formaldehyde
The Journal of the Society of Chemical Industry, Japan, 1969 水溶液中においてメラミン(M)のホルムアルデヒド(F)による初期ヒドロキシメチル化の速度論について約pH8～1の領域で検討した。まず正全速度定数(K)とpHの関係を明かにした。ついでMおよびFは酸性ではそれぞれ分子型および共役酸として平衡状態に存在するため(MH+H3O〓MH2++H2O,HCHO+H3O+〓CH2OH+H2O,K1,K2:平衡定数),ヒドロキシメチル化はこれらの間でおこなわれると考えられ,つぎの速度式を樹てた。dy/dt=k1[MH][HCHO]+k2[MH][CH2OH]+k3[MH2+][HCHO]+k4[MH2+][CH2OH]=k1[MH][HCHO]+k2'[MH][CH2OH]+k4[MH2+][CH2OH](k2'=k2+k3K1/K2=k)(a-y)(b-y)k ...

Low addition of melamine salts for improved Melamine-Urea-Formaldehyde adhesives water resistance
, 2003 The addition of melamine acetate salts to an adhesive glue mix can allow the use of melamine–urea– formaldehyde (MUF) resins of lower melamine contents (rather than just urea–formaldehyde resins) and lower total amounts of melamine.
