甲基异丁基甲酮

甲基异丁基甲酮用途

【用途一】
用作溶剂，也用作润滑油的脱蜡剂
【用途二】
用作色谱分析标准物质、溶剂及萃取剂
【用途三】
4-甲基-2-戊酮又称甲基异丁基酮，是杀鼠剂鼠完的中间体。
【用途四】
香料。主要用以配制朗姆酒、干酪和水果型香精。
【用途五】
该品是优良的中沸点溶剂。用作选矿剂、油品脱蜡用溶剂、彩色影片的成色剂，也用作四环素和除虫菊酯类和DDT的溶剂、粘合剂、橡胶胶水、飞机和模型的蒙布漆。对一些无机盐也是有效的分离剂，可从铀中分出钚，从钽分出铌，从铪分出锆。它的过氧化物是聚酯类树脂聚合反应中非常重要的引发剂。也用于有机合成工业。还可用作乙烯型树脂的抗凝剂和稀释剂。

甲基异丁基甲酮合成路线

详细合成路线

甲基异丁基甲酮上下游产品

甲基异丁基甲酮上游产品

甲基异丁基甲酮下游产品

甲基异丁基甲酮制备

制备方法有异丙醇法和丙酮法。

(1)异丙醇法以异丙醇为原料，在常压、温度180～220℃通过铝铜催化剂，使异丙醇脱氢成丙酮，再与异丙醇缩合脱水而得产品。

(2)丙酮法将丙酮加热，蒸气通过氢氧化钠催化剂，在常压下反应得到双丙醇酮。双丙醇酮在磷酸催化剂存在下进行脱水反应得异丙烯丙酮，将异丙烯丙酮在铜催化剂存在下催化加氢，温度170～200℃，得产品。

精制方法：4-甲基-2-戊酮是由亚异丙基丙酮溶液加氢制取的，因而含有水、亚异丙基丙酮、4-甲基-2-戊醇、酸性物质等杂质。精制方法可参照丁酮的精制法。也可以用少量高锰酸钾回流后，用碳酸氢钠水溶液洗涤，无水硫酸钙干燥，然后蒸馏。酸性杂质可通过一个含有少量活性氧化铝的柱子除去。

(3) 将丙酮加热气化，在氢氧化钠催化作用下，于20℃、常压下进行反应，当温度升至，

反应结束，得到二丙酮醇，在磷酸催化作用下，二丙酮醇脱水，得亚异丙基丙酮，气化后，与氢气混合进入反应器，在铜催化下，于170～200℃、0.3～1MPa下进行加氢反应，然后蒸馏，收集115.5-116.5℃馏分（常压），即为成品，多用2666～6665Pa减压蒸馏获得成品。
