Melamine Chemical Properties,Uses,Production

Chemical Properties

White Solid

Chemical Properties

Melamine is a white crystalline 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.

Definition

A white solid organic compound whose molecules consist of a sixmembered heterocyclic ring of alternate carbon and nitrogen atoms with three amino groups attached to the carbons. Condensation polymerization with methanal or other aldehydes produces melamine resins, which are important thermosetting plastics.

Definition

melamine: A white crystalline compound,C3N6H6. Melamine is a cycliccompound having a six-memberedring of alternating C and N atoms,with three NH2 groups. It can becopolymerized with methanal to givethermosetting melamine resins,which are used particularly for laminatedcoatings.

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.

Hazard

Toxic by ingestion, skin, and eye irritant. Questionable carcinogen.

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)

Safety Profile

Moderately toxic by ingestion and intraperitoneal routes. An eye, skin, and mucous membrane irritant. Causes dermatitis in humans. Questionable carcinogen with experimental carcinogenic and tumorigenic data. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx and CN-.

Potential Exposure

Manufactured from urea, melamine is used in the manufacture of plastics, melamineformaldehyde resins; rubber, synthetic textiles; laminates, adhesives, and molding compound

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.]

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Melamine 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, nitrides, alkali metals, and sulfides.
