Formaldehyde → Melamine formaldehyde

Participants

Reaction Steps

Separately, 11 parts of melamine, 21.2 parts of 37% aqueous formaldehyde solution and 28.2 parts of water were mixed and to the mixture was added sodium hydroxide to adjust pH to 9, followed by heating the mixture to cause dissolution, thereby to obtain an aqueous solution of melamine-formaldehyde pre-condensate. This aqueous solution was added to said emulsion and stirring was continued for 2 hours at 70° C. to complete the reaction.
