异丙醚制备方法及用途

制备方法

工业上,可从丙烯硫酸水合制异丙醇的副产品中回收。丙烯与硫酸反应生成异丙基氢硫酸酯,然后水解为异丙醇。反应过程中,异丙基氢硫酸酯与丙烯继续反应亦生成二异丙基硫酸酯,后者与异丙醇反应生成异丙基氢硫酸酯和二异丙醚。当硫酸水合反应后的物料在解吸塔用蒸汽汽提,使异丙醇与二异丙醚从酸液中释出后,通过蒸馏,从塔顶首先获得二异丙醚。在实验室中,异丙醚可由异丙醇用硫酸脱水得到,也可由异丙醇与丙酮加氢反应来制取。还可由异丙醇与丙烯催化缩合而成。离子交换树脂法也可制取二异丙醚。

合成制备方法

1.工业上，可从丙烯硫酸水合制异丙醇的副产品中回收。丙烯与硫酸反应生成异丙基氢硫酸酯，然后水解为异丙醇。反应过程中，异丙基氢硫酸酯与丙烯继续反应亦生成二异丙基硫酸酯，后者与异丙醇反应生成异丙基氢硫酸酯和二异丙醚。当硫酸水合反应后的物料在解吸塔用蒸汽汽提，使异丙醇与二异丙醚从酸液中释出后，通过蒸馏，从塔顶首先获得二异丙醚。在实验室中，异丙醚可由异丙醇用硫酸脱水得到，也可由异丙醇与丙酮加氢反应来制取。还可由异丙醇与丙烯催化缩合而成。离子交换树脂法也可制取二异丙醚。

2.将异丙醇和浓硫酸混合，加热使之回流，边回流边分出反应生成的水，当水不再生成时，反应结束：

降温后，将反应液倒入冷水，静置分层，弃去水层。油层先经水洗除去未反应的醇，然后加入高锰酸钾溶液，除去烯烃并水洗，用硫酸亚铁水溶液除去过氧化物后水洗，再用氢氧化钠溶液中和所含的酸后用水洗至中性，静置分层，弃去水层，醚层用无水氯化钙干燥脱水，滤去固体干燥剂后，常压蒸馏，收集67～69℃的馏份，即为成品异丙醚。高纯异丙醇可采用含70%异丙醇的废水溶液，先与苯共沸蒸馏，除去水分，冷却后经孔径为0.8μm、0.45μm和0.2μm的三层聚四氟乙烯膜过滤所得。产品中含99.9%的异丙醇、0.1%的水、0.4×10^-6 Ca和0.01～0.09×10^-6的其他阳离子杂质（如 K、Mg、Cr 、Fe和Na）。

用途简介

用作溶剂，用于乙酸或丁酸的稀溶液的浓缩回收，在湿法腈纶工艺中用作硫氰酸钠的萃取溶剂。

用途

1.用作色谱分析标准物质、溶剂及萃取剂，也用于有机合成。异丙醚比乙醚、丙酮的沸点高，挥发性低，对水的溶解能力小。因此，工业上比乙醚更易使用。除作油脂、蜡、矿物油、部分天然树脂、乙基纤维素等的溶剂外，尚用于乙酸或丁酸稀溶液的浓缩回收。与异丙醇的混合物用于油脂脱蜡和蜡的脱油。

2.二异丙醚是动物、植物及矿物性油脂的良好溶剂，可用于从烟草中抽提尼古丁；也是石蜡及树脂的良好溶剂，工业上常将二异丙醚和其他溶剂混合应用于石蜡基油品的脱蜡工艺。作为溶剂也应用于制药、无烟火药、涂料及油漆清洗等方面，二异丙醚具有高辛烷值及抗冻性能，可用为汽油掺合剂。本品易形成过氧化物，在振摇时产生爆炸，常加入对苄基氨基苯酚作稳定剂。二异丙醚的麻醉作用较乙醚轻，但麻醉的持续时间长。

3.用作溶剂，还用于乙酸或丁酸稀溶液的浓缩回收。^[26]

稳定性相关：: 1.化学性质：对碱稳定，氧化、氧化反应和一般醚类相同。氯化时得到双(2-氯异丙基)醚，在氟化氢作用下与苯发生烷基化反应，生成1,4-1,2,4-以及1,2,4,5-异丙基苯。高温高压下与五氧化二磷反应，得到磷酸三异丙酯。异丙醚能生成有爆炸性的过氧化物。异丙基过氧化物[(i-C3H7)2O·O2]稳定，能分解成丙酮和水。贮存中过氧化物分解生成的丙酮与过氧化氢反应，生成有高爆炸性的三丙酮过氧化物。因此，需加入对苯二酚、萘酚、多羟基酚或20%氢氧化钠溶液以抑制过氧化物的生成。
