Abstract

p-Methoxybenzaldehyde (p-MBA) is an important aromatic aldehyde widely used in various industries. Its traditional synthesis methods, such as gas-phase oxidation and chlorination, are hindered by high energy consumption, low selectivity, and environmental concerns. This study explored an alternative greener synthesis of p-MBA through the catalysis of Na-doped Co-Mn-Al oxides (CoMn₃Al_n-Na), which were derived from calcining coprecipitated layered double hydroxide (LDH). The introduction of Na during the catalyst preparation enhanced the catalytic performance by increasing the conversion of p-MT and the yield of p-MBA. The structural integrity and catalytic stability of the synthesized catalyst materials were confirmed by many characterization techniques. This work has developed a viable strategy for the efficient oxidation of p-methoxytoluene (p-MT) under ambient conditions, thereby contributing to the development of sustainable processes for aromatic aldehyde synthesis.

na掺杂Co-Mn-Al氧化物催化对甲氧基甲苯氧化制对甲氧基苯甲醛

对甲氧基苯甲醛（p-MBA）是一种重要的芳香醛，广泛应用于各个工业领域。其传统的合成方法，如气相氧化和氯化，受到高能耗、低选择性和环境问题的阻碍。本研究探索了一种可替代的更环保的p-MBA合成方法，即通过煅烧共沉淀层状双氢氧化物（LDH）得到的na掺杂Co-Mn-Al氧化物（CoMn3Aln-Na）催化合成p-MBA。在催化剂制备过程中引入Na提高了p-MT的转化率和p-MBA的收率，从而提高了催化剂的催化性能。通过多种表征技术证实了所合成催化剂材料的结构完整性和催化稳定性。本研究为环境条件下对甲氧基甲苯（p-MT）的高效氧化开发了一种可行的策略，从而有助于芳香醛合成可持续工艺的发展。
