melaminen.

Brit.

/ˈmɛləmʌɪn/,

/ˈmɛləmiːn/, U.S.

/ˈmɛləˌmin/

Forms: 1800s melamin, 1800s– melamine (in sense 2), 1900s– Melamine.

Origin: A borrowing from German. Etymon: German Melamin.

Etymology: < German Melamin (J. von Liebig 1834, in Ann. der Pharm. 10 18), probably < Melam melam n. (from which it was originally obtained) + -in -ine suffix⁵.Melamine (sense 1) was originally obtained by boiling melam with potassium hydroxide or by heating cyanamide. N.E.D. (1906) gives only the pronunciation (me·lăməin) /ˈmɛləmaɪn/.

1. Chemistry. A crystalline heterocyclic compound, 2,4,6-triamino-1,3,5-triazine, (CNH₂)₃N₃. Also called cyanuramide.

1841 W. T. Brande Man. Chem. (ed. 5) v. 577 Melamin forms anhydrous rhomboidal octoëdra, transparent and colourless.

1844 G. Fownes Man. Elem. Chem. 468 If melam be boiled for a long time in a moderately strong solution of caustic potash,..a crystalline substance separates on cooling, which is called melamine.

1922 Jrnl. Amer. Chem. Soc. 44 488 When guanidine carbonate, or free guanadine is heated melamine, a trimer of cyanamide, is obtained.

1995 New Scientist 5 Aug. 44/2 Polymer-like threads form from a solution containing two different kinds of molecule, one based on the compound melamine and the other a type of compound called a diimide.

2. Plastic derived from melamine resin (cf. melamine resin n. at Compounds 2); (also) the resin itself. Frequently attributive: made of this plastic.
