-
Paragraph 0035-0036; 0041-0042, (2021/11/03)
The invention discloses a myricetin derivative containing 1, 3 and 4 - oxadiazole thioether and a preparation method and application thereof, wherein the structural general formula is as follows: R is a substituted phenyl group, an aromatic heterocyclic group or a substituted aromatic heterocyclic group. n: The number of carbons in the carbon chain is 2 , 3, 4, 5, 6. The substituted phenyl group is on the phenyl ring, and the para position contains C1 - 6 alkyl, C1 - 6 alkoxy, nitro, halogen atom and hydrogen atom. The aromatic heterocyclic group is thienyl, furyl, pyrrolyl, pyridyl. Substituents on the substituted aromatic heterocycle are ortho, meta, para, C1 - 6-containing alkyl groups, C1 - 6 alkoxy groups, nitro groups, halogen atoms, hydrogen atoms. The synthesized compound has a good control effect on tobacco mosaic viruses, citrus canker germs, kiwi fruit ulcer germs and rice bacterial blight bacteria.

Herein, we describe the synthesis of tunable aryl imidazolium ionic liquid catalysts and tested for esterification of fatty acids to biodiesel. In this work, six tunable aryl imidazolium ionic liquids (TAIILs) 1a-1f were prepared. These ionic liquids were used as the economical and reusable catalysts for the synthesis of biodiesel fuels. The reaction has been preceded in a monophase at 80 °C for 4 h, after which the product was separated from the catalyst system by a simple liquid/liquid phase separation at room temperature with excellent yields. With the simple post-process, the catalyst is reusable at least 6 times. This novel method offers a short reaction time, good yields, and environmentally benign characteristics.
