Paragraph 0022-0023, (2019/07/04)
The present invention discloses a solid supported ionic liquid catalytic synthesis of stearic acid pentaerythritol ester of method, characterized in that in order to stearic acid and pentaerythritol as the raw materials, to solid supported type imidazole ion liquid as the use of the catalyst. The invention adopts the sol-gel process solid-ionic liquid, the catalyst amount is alcohol, acid always mole number of 1% - 5%, the reaction temperature is at 110 - 170 °C, normal pressure, reaction time 1 - 5 h; the characteristic of this invention is not adopted the pollution to the environment of the concentrated sulfuric acid, with the traditional inorganic acid as compared with the catalyst, solid-ionic liquid has high catalyst activity, mild reaction, esterification rate high, obtained by the production process is simplified, catalyst recovery simple operation and the like.

More than green alternatives to traditional volatile molecular organic solvents, protic ionic liquids as dual solvent-catalysts have been successfully used to promote reactions of organoamines with oxadiazoles to afford sterically hindered 1,2,4-triazoles. Among the tested protic ionic liquids, pyridinium trifluoroacetate and acetate showed the highest efficiency for the reactions of arylamines and alkylamines, respectively, indicating that tunable catalysis could be readily effected with protic ionic liquid solvent-catalysts by simply tuning their cation and anion counterparts. A general and efficient approach has been developed for synthesis of multiply substituted 1,2,4-triazoles based on the tunable protic ionic liquid solvent-catalyst systems.
