Melamine

************From Wiki**************************

This article is about the chemical substance called melamine. The term "melamine" may also be used to refer to melamine resin, a plastic made from melamine and formaldehyde.
Not to be confused with melanin, a pigment found in skin and hair, or with melatonin, a naturally occurring hormone regulating the circadian rhythms of most animals.

Melamine is an organic base with the chemical formula C3H6N6, with the IUPAC name 1,3,5-triazine-2,4,6-triamine. It is only slightly soluble in water.

Melamine is a trimer of cyanamide. Like cyanamide, it is 66% nitrogen (by mass) and provides fire retardant properties to resin formulas by releasing nitrogen when burned or charred. Dicyandiamide (or cyanoguanidine), the dimer of cyanamide, is also used as a fire retardant.

Melamine is a metabolite of cyromazine, a pesticide. It is formed in the body of mammals who have ingested cyromazine.[2] It was also reported that cyromazine is converted to melamine in plants.[3][4]

**Synthesis***************


Melamine was first synthesized by Liebig in 1834. In early production, first calcium cyanamide is converted into dicyandiamide, then heated above its melting temperature to produce melamine. However, today most industrial manufacturers use urea in the following reaction to produce melamine

6 (NH2)2CO → C3H6N6 + 6 NH3 + 3 CO2
It can be understood as two steps. First, urea decomposes into cyanic acid in an endothermic reaction (NH2)2CO → HCNO + NH3. Then cyanic acid polymerizes to form melamine and carbon dioxide: 6 HCNO → C3H6N6 + 3 CO2. The second reaction is exothermic and the overall process is endothermic.

The above reaction can be carried out by either of two methods:catalyzed gas-phase production or high pressure liquid-phase production. In one method, molten urea is introduced onto a fluidized bed with catalyst for reaction. Hot ammonia gas is also present to fluidize the bed and inhibit deammonization. The effluent then is cooled. Ammonia and carbon dioxide in the off-gas are separated from the melamine-containing slurry. The slurry is further concentrated and crystallized to yield melamine.[5] Major manufacturers and licensors such as DSM, BASF and Eurotecnica have developed some proprietary methods.

The off-gas contains large amounts of ammonia. Therefore melamine production is often integrated into urea production which uses ammonia as feedstock.

Crystallization and washing of melamine generates a considerable amount of waste water, which is a pollutant if discharged directly into the environment. The waste water may be concentrated into a solid (1.5-5% of the weight) for easier disposal. The solid may contain approximately 70% melamine, 23% oxytriazines (ammeline, ammelide and cyanuric acid), 0.7% polycondensates (melem, melam and melon).[6]


********衛生檢驗標準也流行向中國香港看齊...還比中國豬不如


真是有夠悲哀

真要快要無言了
有人舔中共的xx到這種程度......
狗官狗官狗官
害死人

只有上街
才能讓這個規定下架
如此狗官下台!

有人還記得日本的毒水餃嗎？

當初中日雙方展開聯合調查，兩邊都派出調查團，到對方國內調查（這大概是我們內閣總理參考的方式），結果大陸由國家質監局和公安部出面發表他的的“初步調查結果”（國家背書的喔）聲稱：這不是一起因農藥殘留引起的食品安全事件，而是人為下毒的個案；下毒發生在中國境內的可能性極小；農藥可以從外部滲透到袋子內部...等等。

結果日本怎麼反擊？他們調查毒水餃裡發現的致毒農藥甲胺磷，在中國很常見，在日本境內幾乎不流通；而且，該種甲胺磷含不純物質多，與日本的甲胺磷不同。另外，發現毒餃的千葉、兵庫、課餘等縣，在日本國內的運輸途徑不同，怎麼可能會出現同樣的含毒結果？針對大陸“農藥可以從外部滲透到袋子內部”的說法，日方聲明：試驗結果顯示，這些農藥很難從袋子外部滲透到內部。日方要求中方提供支援其說法的科學依據。

今天換成毒奶粉，祖國說都慶不可能有毒，於是偉大的政府立刻修正說法，因為三聚氰胺被廣泛運用於食品包裝及容器上，不少食品或多或少會因此滲入微量三聚氰胺，先前以「不得檢出」標準，查驗產品過於嚴苛，其實是誤會一場。

政府這樣做只會加重民眾對中國食品的不信任，以及對奶製品的恐懼，除此之外根本無濟於事，這下子誰敢相信奶製品是「符合食品標準」，還是「完全不含」三聚氰胺？為了保險起見乾脆不要碰最好，對那些業者不是更重創嗎？

還是政府想賭人民是健忘的？過一陣子就沒事了，馬照跑，舞照跳，一切歌舞升平？

台灣己經無政府了

看了只能搖搖頭,

今年雙十國宴

外賓都吃奶製品菜,

飲料:奶茶(可續杯,內含合乎標準三聚氰氨2.5ppm)

餐後點心:蛋糕 (內含合乎標準三聚氰氨2.5ppm)

擔心健康者:免費提供2000cc礦泉水,有人陪您跑步,游泳,幫助您代謝快一點

這件事情我記得最後是....
中國說是水餃員工因為對公司不滿，故意把農藥加入水餃內

很明顯的意圖
放寬標準很明顯是為了救市場
因為中標的那些供應商供應範圍實在太廣了

不過這些高層真的是眼光短淺
他們沒想到這樣只會使所有的廠商一起死
民眾可不是白痴
聽你放寬標準就乖乖吃微量的三聚氰氨
絕大部分的會變成不吃或少吃吧
管你檢查結果有沒有通過標準

現在看來未來最有前景的是泌尿科吧

恩....感謝提供資料
那跟我猜的不錯,用GC作,mass作最後的detector
所以偵測極限較差,只能到5ppm
而用HPLC作,因為最後用UV作detector
偵測極限可以到2ppm
但還是差呀~順便附上剛找到的

參考一下

另一個有用的

malamlne如果用HPLC+螢光,或者GC+螢光我想一定更好
可是他們很像很愛用MS,應該是已經設好資料庫了(這也沒錯,mass的確是致命性的證據)
但如果我們已知是malamlne,應該有很多法可試
原來業界是這樣,又多瞭解一點了,感謝!!!
