三聚氰胺三聚氰胺(Melamine)(化学式:C3H6N6),俗称密胺、蛋白精,IUPAC命名为“1,3,5-三嗪-2,4,6-三氨基”,是一种三嗪类含氮杂环有机化合物,被用作化工原料。
它是白色单斜晶体,几乎无味,微溶于水(3.1g/L常温),可溶于甲醇、甲醛、乙酸、热乙二醇、甘油、吡啶等,不溶於丙酮、醚类、对身体有害,不可用於食品加工或食品添加物。
然而,近日青海、甘肃、吉林等省再现三聚氰胺超标奶粉,超标500余倍。
很可能是对尚未完全销毁的“三鹿问题奶粉”进行加工、销售。
物理性质三聚氰胺性状为纯白色单斜棱晶体,不可燃,无味,低毒,密度1.573g/cm3 (16℃)。
常压熔点354℃,急剧加热则分解;快速加热升华,升华温度300℃。
在水中溶解度随温度升高而增大,在20℃时,约为3.3 g/L,即微溶于冷水,溶于热水,极微溶于热乙醇,不溶于醚、苯和四氯化碳,可溶于甲醇、甲醛、乙酸、热乙二醇、甘油、吡啶等。
化学性质呈弱碱性(pH值=8),与盐酸、硫酸、硝酸、乙酸、草酸等都能形成三聚氰胺盐。
在中性或微碱性情况下,与甲醛缩合而成各种羟甲基三聚氰胺,但在微酸性中(pH值5.5~6.5)与羟甲基的衍生物进行缩聚反应而生成树脂产物。
遇强酸或强碱水溶液水解,胺基逐步被羟基取代,先生成三聚氰酸二酰胺,进一步水解生成三聚氰酸一酰胺,最后生成三聚氰酸。
合成工艺三聚氰胺最早被李比希于1834年合成,早期合成使用双氰胺法:由电石(CaC2)制备氰胺化钙(CaCN2),氰胺化钙水解后二聚生成双氰胺(dicyandiamide),再加热分解制备三聚氰胺。
目前因为电石的高成本,双氰胺法已被淘汰。
与该法相比,尿素法成本低,目前较多采用。
尿素以氨气为载体,硅胶为催化剂,在380-400℃温度下沸腾反应,先分解生成氰酸,并进一步缩合生成三聚氰胺。
反应式为:6 CO(NH2)2 → C3N6H6 + 6 NH3 + 3 CO2生成的三聚胺气体经冷却捕集后得粗品,然后经溶解,除去杂质,重结晶得成品。
三聚氰胺性状为纯白色单斜棱晶体,无味,密度1.573g/cm3 (16℃)。
常压熔点354℃(分解);快速加热升华,升华温度300℃。
溶于热水,微溶于冷水,极微溶于热乙醇,不溶于醚、苯和四氯化碳,可溶于甲醇、甲醛、乙酸、热乙二醇、甘油、吡啶等。
低毒。
在一般情况下较稳定,但在高温下可能会分解放出氰化物。
呈弱碱性(pKb=8),与盐酸、硫酸、硝酸、乙酸、草酸等都能形成三聚氰胺盐。
在中性或微碱性情况下,与甲醛缩合而成各种羟甲基三聚氰胺,但在微酸性中(pH 值5.5~6.5)与羟甲基的衍生物进行缩聚反应而生成树脂产物。
遇强酸或强碱水溶液水解,胺基逐步被羟基取代,先生成三聚氰酸二酰胺,进一步水解生成三聚氰酸一酰胺,最后生成三聚氰酸。
主要用途三聚氰胺是一种用途广泛的基本有机化工中间产品,最主要的用途是作为生产三聚氰胺甲醛树脂(MF)的原料。
三聚氰胺还可以作阻燃剂、减水剂、甲醛清洁剂等。
该树脂硬度比脲醛树脂高,不易燃,耐水、耐热、耐老化、耐电弧、耐化学腐蚀、有良好的绝缘性能、光泽度和机械强度,广泛运用于木材、塑料、涂料、造纸、纺织、皮革、电气、医药等行业。
其主要用途有以下几方面:(1)装饰面板:可制成防火、抗震、耐热的层压板,色泽鲜艳、坚固耐热的装饰板,作飞机、船舶和家具的贴面板及防火、抗震、耐热的房屋装饰材料。
(2)涂料:用丁醇、甲醇醚化后,作为高级热固性涂料、固体粉末涂料的胶联剂、可制作金属涂料和车辆、电器用高档氨基树脂装饰漆。
(3)模塑粉:经混炼、造粒等工序可制成蜜胺塑料,无度、抗污,潮湿时仍能保持良好的电气性能,可制成洁白、耐摔打的日用器皿、卫生洁具和仿瓷餐具,电器设备等高级绝缘材料。
(4)纸张:用乙醚醚化后可用作纸张处理剂,生产抗皱、抗缩、不腐烂的钞票和军用地图等高级纸。
(5)三聚氰胺甲醛树酯与其他原料混配,还可以生产出织物整理剂、皮革鞣润剂、上光剂和抗水剂、橡胶粘合剂、助燃剂、高效水泥减水剂、钢材淡化剂等。
三聚氰胺简单介绍
三聚氰胺(Melamine,108-78-1)是一种有机碱,是具有1、3、5-三嗪骨架的氰胺三聚体。
像氰酰胺一样,三聚氰胺含有66%的氮,如果与树脂混合,由于在燃烧或炭化时会释放出氮气,因此具有阻燃性,并具有其他工业用途。
三聚氰胺也是农药嘧啶嗪的代谢产物。
它是在摄入环丙嗪的哺乳动物体内形成的。
三聚氰胺也进入了三聚氰胺多磺酸盐的生产过程,三聚氰胺多磺酸盐被用作高效减水剂,用于制造高强度混凝土。
三聚氰胺(108-78-1,Melamine)能升华, 呈弱碱性, 溶于热水,微溶于冷水,极微溶于热乙醇,不溶于乙醚、四氯化碳和苯,致死量(小鼠,经口)1600mg/kg,有刺激性,有致癌可能性.。
