melamine

mel·a·mine

M0202400 (mĕl′ə-mēn′)n.1. A white crystalline compound, C₃H₆N₆, used in making melamine resins and waterproof coatings, for tanning leather, and as an additive to fertilizer to regulate the rate of nitrogen release. Melamine has also been used as an illicit and harmful additive to foodstuffs to increase the apparent amount of protein present based upon assays for nitrogen.2. A plastic made from melamine resin.

[German Melamin : blend of Melam, distillate of ammonium thiocyanate (mel-, arbitrary pref. + Am(monium), ammonium) and Amin, amine.]

melamine

(mĕl`əmēn'), common name for 2,4,6-triamino-1,3,5-triazine. Melamine is a trimer (see polymerpolymer
, chemical compound with high molecular weight consisting of a number of structural units linked together by covalent bonds (see chemical bond). The simple molecules that may become structural units are themselves called monomers; two monomers combine to form a dimer,

any of a class of amorphous solids or semisolids. Resins are found in nature and are chiefly of vegetable origin. They are typically light yellow to dark brown in color; tasteless; odorless or faintly aromatic; translucent or transparent; brittle, fracturing like glass;

Melamine also is notorious as a toxic adulterant of food and feed products. It is added to boost a product's nitrogen content, which is used by certain tests to estimate the product's protein content.

Melamine

2,4,6-triamino-5-triazine; colorless crystals. Melting point, 354°C (with decomposition). It is virtually insoluble in cold water and most organic solvents. Melamine is a base, which interacts with acids to form salts (for example, C₃H₆N₆HCl) that decompose upon heating. It is prepared from dicyandiamide, (NH₂— C≡N)₂, at a temperature of 180°-500° C and a pressure of 4–20 meganewtons per sq m (40–200 kilograms-force per sq cm).

Melamine is used in the manufacture of melamine-formaldehyde resins (plastics, adhesives, and varnishes), ion-exchange resins, tanning agents, and hexachloromelamine (which is used in the preparation of dyes and herbicides).

melamine

[′mel·ə‚mēn] (organic chemistry) C₃H₆N₄ A white crystalline compound that is slightly soluble in water, melts at 354°C and is a cyclic trimer of cyanamide; used to make melamine resins and in tanning of leather.

1. a colourless crystalline compound used in making synthetic resins; 2,4,6-triamino-1,3,5-triazine. Formula: C₃H₆N₆ 2. melamine resin or a material made from this resin

melamine

An organic base and trimer of cyanamide that is 67% nitrogen by weight. It has been used by some Chinese manufacturers to inflate the apparent protein content of foods and feeds, so that cheap ingredients can be passed off as concentrated proteins. While melamine itself is not toxic at low levels, in those cases in which adulteration was discovered nephrotoxic cyanuric acid had also been added.

melamine

A chemical derivative of urea, which when combined with formaldehyde is used to produce hard plastic laminates such as those used in countertops. Its chemical formula is C3H6N6. It has been used in foods, fertilizers, and other consumer products (such as animal feed) to increase their nitrogen content. When chemically complexed with cyanuric acid, it is toxic.
