18、ionSulfonationDistillation第一章第一章間二甲苯的發(fā)展現(xiàn)狀間二甲苯的發(fā)展現(xiàn)狀間二甲苯(MX)是混合二甲苯和C8芳烴的一種組分。混合二甲苯含鄰二甲苯(OX)、對(duì)二甲苯(PX)和MX3種二甲苯異構(gòu)體；C8芳烴除含有以上3種二甲苯異構(gòu)體之外一般還含有乙苯。在混合二甲苯中，MX的含量最大，但是目前它在工業(yè)上的用量卻遠(yuǎn)不及其它兩種異構(gòu)體，這主要是MX的性質(zhì)與其它異構(gòu)體的性質(zhì)接近，特別是MX和PX的沸點(diǎn)相差很小，長(zhǎng)期以來(lái)人們

19、找不到用比較經(jīng)濟(jì)的方法從異構(gòu)體中分離出高純度MX的方法。因此，MX在工業(yè)中多異構(gòu)成PX和OX，或用作調(diào)和汽油的組分，或以混合二甲苯的形式當(dāng)作溶劑使用。隨著近代石油化工工業(yè)的發(fā)展，人們不斷發(fā)現(xiàn)分離高純度MX的方法，經(jīng)分離和氧化MX生成的間苯二甲酸(IPA)及其衍生物是生產(chǎn)改性不飽和樹(shù)脂、醇酸樹(shù)脂、油墨、聚酯纖維染色改性劑、農(nóng)藥和染料中間體的重要的有機(jī)化工原料，因此也就帶動(dòng)了MX工業(yè)的發(fā)展。我國(guó)MX在分離和應(yīng)用方面都起步較晚，直到2000年
