General description
叔-丁醇(tBA)是一种叔醇。它在固体酸催化剂存在下,发生脱水反应,生成具有高选择性的异丁烯。以大豆油脱臭馏出物(SODD)为反应介质,采用脂肪酶介导的醇解反应制备生物柴油。已有研究关于在锆(TPA/ZrO2)催化剂上负载12-钨磷酸,tBA对对甲酚进行丁基化,生成2-叔丁基对甲酚(TBC)、2,6-二叔丁基对甲酚(DTBC)和叔丁基对甲苯醚。已有采用基于伪势方法的 从头 密度泛函理论(DFT)对tBA在Si(001)-(2×1)表面的相互作用行为进行了评估。
Application
- 在有无脂肪酶B存在的情况下,研究核糖-油酸酯的合成。:该研究以叔丁醇为溶剂,在脂肪酶B存在和不存在的情况下,研究了酶催化过程的效率和有效性。该研究探讨了酶催化过程的效率和效果,强调了叔丁醇对合成反应的影响。这些发现有助于理解分析化学中的酯化过程,在开发新的合成方法方面具有潜在的应用价值(Çetinkaya et al., 2020)。
