MIL-101(Cr)-SO₃H was prepared by a one-pot synthesis method using CrO₃ or Cr(NO₃)₃^·9H₂O as a Cr source and 2-sulfoterephthalic acid monosodium salt as a ligand with three different mineralizers, HCl, HF and NaAC, respectively. Among the prepared catalysts, MIL-101(Cr)-SO₃H, which uses HCl as a mineralizer, has a high specific surface area and the strongest acidity compared with the other two mineralizers. When these catalysts were used to catalyze the esterification of cyclohexene with formic acid, MIL-101(Cr)-SO₃H prepared using HCl as a mineralizer possessed the highest catalytic activity in the esterification, because the conversion rate of cyclohexene is 63.97%, whereas MIL-101(Cr)-SO₃H prepared using NaAC and HF as a mineralizer shows cyclohexene conversion rates of 38.40% and 32.46%, while their selectivity to cyclohexyl formate is about 97.50%. MIL-101(Cr)-SO₃H with HCl as a mineralizer can be reused three times in succession without any loss of catalytic activity.

三种MIL-101(Cr)-SO3H用于甲酸酯化环己烯的比较研究

MIL-101(Cr)-SO ₃ H 以CrO ₃或Cr(NO ₃ ) ₃^· 9H ₂ O为Cr源，2-磺基对苯二甲酸一钠盐为配体，三种不同的一锅法合成。矿化剂分别为 HCl、HF 和 NaAC。在所制备的催化剂中，以HCl为矿化剂的MIL-101(Cr)-SO ₃ H与其他两种矿化剂相比具有较高的比表面积和最强的酸性。当这些催化剂用于催化环己烯与甲酸的酯化反应时，MIL-101(Cr)-SO ₃使用 HCl 作为矿化剂制备的 H 在酯化反应中具有最高的催化活性，因为环己烯的转化率为 63.97%，而使用 NaAC 和 HF 作为矿化剂制备的 MIL-101(Cr)-SO ₃ H 的环己烯转化率为38.40%和32.46%，而它们对甲酸环己酯的选择性约为97.50%。MIL-101(Cr)-SO ₃ H 与 HCl 作为矿化剂可以连续重复使用 3 次而不会损失任何催化活性。
