style="text-indent:25px">根據(jù)原料不同，丙二胺的生產(chǎn)方法可分為二種。一種是以環(huán)氧丙烷、1，2-丙二醇、異丙醇氨、1，3-丙二醇、丙烯醛、丙烯腈為原料，與氨反應(yīng)，或先與氨反應(yīng)，然后加氫，此法優(yōu)點是流程簡單，無污染，投資少，能耗低，催化劑價格昂貴。另一種方法是1，2-二氯丙烷氨解法。生產(chǎn)過程簡述如下：將1，2二氯丙烷與液氨加入防腐的釜式反應(yīng)器中，通過冷卻使反應(yīng)溫度控制在160℃左右，反應(yīng)結(jié)束，將物料送至中和器用氫氧化鈉溶液中和物料中的氯化氫。由于丙二胺與水不共沸，可以精餾分離得到98%以上丙二胺。1,2-丙二胺是一種化學(xué)物品，分子式是C3H10N2。南通巴斯夫1-2丙二胺哪個品牌好</p><p

style="text-indent:25px">丙二胺作為一種重要的精細(xì)有機化工中間體，其工業(yè)應(yīng)用普遍，需求量大。普遍用于醫(yī)藥燃料和有機合成。丙二胺是低級脂肪胺，有兩個同分異構(gòu)體，1,2-丙二胺和1，3-丙二胺。丙二胺和其他脂肪酸一樣是極性化合物，能形成氫鍵，氮原子上有未共用電子對，由于這對未共用電子對具有親核性，容易與一些親電性化合物發(fā)生反應(yīng)。如它是一種有機堿可以和無機酸、有機酸作用生成相應(yīng)的無機鹽、有機鹽；與鹵代烴、醇等垸基化試劑作用；與有機酸、酰氯、酯和酸酐發(fā)生?；饔?；與羰基化合物反應(yīng)生成不穩(wěn)定的Schiff堿，Schiff堿加氫還原可以制取烷基取代的丙二胺；還可以和不飽和化合物，
