Abstract
本发明提供了一种以Pd‑Rh作为反应催化剂,在甲基自由基试剂作用下合成三甲基氢醌二酯的方法。其制备方法为:(1)Rh催化剂制备:以联芳香杂环化化合物作为配体,三氯化铑为底物合成Rh催化剂;(2)以(1)中合成的Rh催化剂和醋酸钯作为催化剂,以2,6‑二甲基苯酚为原料,在甲基自由基试剂和氧化剂作用下发生反应合成三甲基氢醌产物,然后经过酰化反应得到三甲基氢醌二酯。该方法使用价格低廉的2,6‑二甲基苯酚为原料,使用了痕量催化剂,同时具有较为优异的选择性,避免了强酸催化剂的使用,反应较为绿色环保,适合工业化放大生产。
Description
技术领域
本发明属于化学合成技术领域,具体涉及一种以Rh催化剂和醋酸钯作为双金属催化剂,以2,6-二甲基苯酚为起始原料催化合成2,3,5-三甲基氢醌二酯的新型合成路线。
背景技术
维生素E由于其在人体内可以起到抗衰老、提高免疫力等作用,在食品、医药、化妆品等领域得到广泛应用。作为合成维生素E重要中间体的三甲基氢醌二酯一直是该领域重点研究内容,传统的合成路线有均三甲酚法、偏三甲苯法、异佛尔酮法:
1.均三甲酚法
均三甲酚法是以氢氧化钠为催化剂,均三甲酚在高压氧气中氧化为4-羟基-2,4,6-三甲基-2,5-环己二烯酮(2);(2)于250℃经甲基转位后再经还原合成TMHQ。该路线虽然整体路线较短,但是2,4,6-三甲基苯酚原料价格较高,难以实现大规模生产。
2.偏三甲苯法
该方法利用偏三甲苯与丙烯经烷基化反应制得5-异丙基偏三甲苯,后经磺化、碱熔、脱去异丙基合成TMHQ。该方法条件温和,可在常压下进行,但反应选择性差,副产物难以分离除去。
3.异佛尔酮氧化法
异佛尔酮氧化法是丙酮首先聚合为异佛尔酮,然后经过异构、氧化、重排酰化得到三甲基氢醌二酯。该方法原料合成路线复杂,且使用强酸作为催化剂,在工业化生产中对后续反应管线具有一定的腐蚀。
DE2149159A提出使用质子酸或者Lewis酸作为催化剂,实现了以KIP和醋酸酐为原料发生重排反应得到三甲基氢醌二酯,但是该方法必须使用过量的酸催化剂才能实现较高转化率,并且产品选择性较低,分离收率最高为66%,所以该方法具有一定的局限性。
CN1241559A报道了通过氧代异佛尔酮的重排生成三甲基氢醌二酯的方法,该方法使用高氯酸、硫酸或氟磺酸等强酸催化体系,整个工艺产生大量含酸废水,导致废水处理存在问题,且对于整个设备管线的运行均会产生影响。
