三聚氰胺合成路线

三聚氰胺上下游产品

三聚氰胺制备

1、双氰胺法 由双氰胺在甲醇溶剂中,于200℃与氨反应而得。

双氰胺常压沸腾法的工艺流程为:

此法每吨产品需消耗双氰胺(98%)1180kg,液氨30kg。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。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。尿素法生产三聚氰胺每吨产品消耗尿素约3800kg、液氨500kg。

2、尿素常压沸腾法 尿素以氨气为载体,以硅胶为催化剂,在380~400℃下分解成氰酸,进一步缩聚得三聚氰胺。生成的三聚氰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。 生成的三聚氰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。工艺流程为: 3、尿素法 该法按压力条件可分为高压法和低压法。由熔融的尿素和氨反应而得。该反应是吸热反应。高压(6.0-8.0MPa)液相法不用催化剂。低压(0.2-0.8MPa)气相法采用三氧化二铝-二氧化硅作催化剂。高温高压液相法主要有以下几种:(1)Nissan法 将熔融尿素加压到10.0MPa,经洗涤吸收离开反应塔的尾气中残佘蜜胺后进入反应塔,液氨加压到10.0MPa,升温到400℃进入 反应塔。在压力为10.0MPa、湿度380-400℃的条件下,尿素转化为蜜胺。反应尾气回收塔中用稀甲胺液吸收成浓甲胺液,送入尿素装置。从反应塔出来的溶液(大部分是蜜胺)与热气混合后进一步反应,然后减压淬冷到180℃得到含蜜胺20%-30%(质量分数)的溶液。待压力为1.5MPa时,去氨汽提塔汽提出大部分氨,再经过滤、结晶、干燥得产品,收率为85%-90%。 (2)Mqntedison法 将熔融尿素加压加热到8.0MPa、135℃,使其进入反应塔,同时加入适量420℃的氨,反应压力8.0MPa,温度380℃。反应塔减压到2.5MPa,反应生成的混合物去淬冷塔被来自吸收塔的甲胺冷却到160℃。塔顶出来的反应尾气经处理后去尿素装置。塔底溶液减压到0.5MPa进入汽提塔,汽提出残佘的氨和二氧化碳在吸收塔中被吸收生成稀甲胺液,然后返回到淬冷塔作冷却液。汽提塔底部出来的蜜胺溶液,被循环母液稀释,经活性炭净化、脱色后过滤、结晶、分离、干燥即得产品,收率为85%-90%。 4. 三聚氰胺以尿素为原料,氨气为
液化载气,以硅胶为催化剂进行气固相催化反应,多采用半干式常压法工艺,在380~400℃下合成三聚氰胺,并使三聚氰胺在凝华器中结晶,粗品经溶解、过滤、结晶后制成成品。或者由双氰胺在甲醇溶剂中,于200℃与氨反应而得。
