The sustainable and eco-compatible valorization of renewable feedstocks to synthesize important chemicals is an intense area of research. Currently, ozonolysis is the sole industrial process for the sustainable synthesis of azelaic acid, predominately utilizing oleic acid. Here, the work described the utilization of a non-edible Triadica sebifera seed oil and other vegetable oils to synthesize azelaic acid in 48–72% yields. The process utilized a recyclable WO3-Na2SnO3 based commercial heterogeneous catalytic system and a greener oxidant (30% aq·H2O2), which resulted in a less harmful impact on the environment. The catalytic system was also utilized to synthesize other commercially important dicarboxylic acids, such as succinic acid with 58% yield and suberic acid with 56–60% yields. A non-fatty acid-containing oil (anise oil) was used to synthesize p-anisic acid at the gram scale in a 76% yield. A range of benzoic acid derivatives has also been synthesized by utilizing various substituted styrenes in 52–88% yields.

在非均相催化剂上从植物油可持续生产壬二酸

合成重要化学品的可再生原料的可持续和生态兼容增值是一个重要的研究领域。目前,臭氧分解是可持续合成壬二酸的唯一工业过程,主要利用油酸。在这里,这项工作描述了利用不可食用的三叶草种子油和其他植物油以 48-72% 的收率合成壬二酸。该工艺利用可回收的 WO 3 -Na 2 SnO 3基商业多相催化系统和更环保的氧化剂(30% aq·H 2 O 2),从而减少了对环境的有害影响。该催化系统还用于合成其他商业上重要的二元羧酸,例如产率 58% 的琥珀酸和产率 56-60% 的辛二酸。使用不含脂肪酸的油(茴香油)以 76% 的产率合成克级茴香酸。一系列苯甲酸衍生物也已通过利用各种取代的苯乙烯以 52-88% 的收率合成。
