Melamine Chemical Properties,Uses,Production

Chemical Properties

White Solid

Uses

A compound that forms synthetic resins with formaldehyde

Uses

Forms synthetic resins with formaldehyde.

Definition

ChEBI: A trimer of cyanamide, with a 1,3,5-triazine skeleton.

General Description

Colorless to white monoclinic crystals or prisms or white powder. Sublimes when gently heated.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Melamine is incompatible with strong oxidizing agents and strong acids . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Fire Hazard

Literature sources indicate that Melamine is nonflammable.

Contact allergens

Melamine-formaldehyde resin (MFR) results from condensation of melamine and formaldehyde. It is anactive ingredient of strong (reinforced) plasters, such as industrial or some dental plasters used for molding.It is also used as a textile finish resin. MFR acts as an allergen generally because of formaldehyde releasing (see Chap. 40)

Purification Methods

Crystallise Melamine from water or dilute aqueous NaOH. It sublimes at ~240o on prolonged heating. [Beilstein 26 I 74, 26 II 132, 26 III/IV 1253.]
