Formaldehyde → Melamine formaldehyde

Participants

Reaction Steps

170.1 g (0.9 mol) of melamine and 61.7 g of an 80% strength aqueous solution of N,N',N"-tris-(5-hydroxy-3-oxapentyl)-melamine (0.1 mol) were mixed with 45.8 g of paraformaldehyde, 3.72 g of bisphenol A, 1.5 ml of diethylaminoethanol and 110.7 g of 40% strength aqueous formaldehyde solution and 1.6 g of a methylol compound. The reaction mixture was refluxed until it had a viscosity of 630 Pa.s (98° C.).
