Civil report 2008.09.24. On September 17, the country handles incident of milk powder of infant of 3 deer card to lead group controller to say, each district already reported because of,have 6244 edible after milk powder of recipe of infant of 3 deer card by clinical diagnose contract kidney and urology disease. According to detecting, in milk powder of recipe of infant of 3 deer card 3 get together cyanogen amine content is highest achieve every kilograms of 2563 milligram unexpectedly, and this kind of industrial chemicals that cannot appear in food, bring about a baby to have kidney and the prime criminal with calculous urology namely.

So, 3 get together what thing is cyanogen amine after all? 3 get together cyanogen amine, english Melamine, latin name Cyanuramide, structural formula is C3H6N6, weigh sweet amine again, 2, 4, 6- 3 amino - 1, 3, 3 Qin of 5- . 3 get together cyanogen amine exterior and physical character are crystal of arris of pure white monocline (pulverous shape) , white insipidity, with resemblance of albumen pink surface. Melting point 345 ℃ (decompose) , density 1.573 grams / every are cubic centimeter (16 ℃ ) . Summary dissolve reachs alcohol at water, not dissolve is mixed at ether, benzene 4 chloridize carbon. Wait to be able to form salt with acid of hydrochloric acid, vitriolic, nitric acid, second, oxalic acid.

Below neuter or small basic case, 3 get together cyanogen amine becomes all sorts of hydroxide with formaldehyde condensation methylic 3 get together cyanogen amine, but in small acidity (PH is worth 5.5-6.5) as methylic as hydroxide ramification undertakes condensation polymerization reacts and make colophony product. 3 get together cyanogen amine encounters strong acid or hydrolyze of alkali aqueous solution, amine radical is replaced by hydroxyl stage by stage, the gentleman is become 3 get together cyanic acid 2 acyl amine, farther hydrolyze is generated 3 get together cyanic acid one acyl amine, generate finally 3 get together cyanic acid.

Say simply, 3 get together cyanogen amine is semifinished product of a kind of main organic chemical industry, basically use make 3 get together cyanogen amine colophony, it is better to have be able to bear or endure ability in swimming, hear resistance, be able to bear or endure electric arc sex, anti-flammability. Can be used at installing plaque make, use at auxiliary of intensifier of paper of agent of amino and plastic, bind, coating, money, spin to wait.

From the point of these circumstances, 3 get together cyanogen amine is a kind of very dinkum chemical industry material and raw material only, touch completely with food not above. So, if human body is fed by accident, healthy meeting gets greater harm. Although some animal test results make clear large dose 3 get together after cyanogen amine raise feeds bandicoot, hare and dog, did not observe apparent toxic phenomenon, but the animal is absorbed for a long time 3 get together the harm that cyanogen amine can cause reproduction, urology, produce urology and nephritic stone. And, 3 get together cyanogen amine can cause experimental animal death, bandicoot profess to convinced 3 get together the fatal dose of half of the tested animals of cyanogen amine is more than 3 grams / kilogram weight.
