Cyclodehydration of Diols in Acidic Ionic Liquids

Abstract

Cyclodehydration of Diols in Acidic Ionic Liquids In the presence of sulfonic acid group functionalized Bronsted-acidic ionic liquids, cyclodehydration of 1,2-ethanediol and 1,4-butanediol is investigated. The role of structure and catalytic activity of ionic liquids on the formation of cyclic ethers: 1,4-dioxane and tetrahydrofuran - is determined.

Effect of solvent, in the sol–gel synthesis of CoAl2O4, on the structure and catalytic properties in 1,4-butanediol dehydrocyclization

“…It could be obtained through dehydration of 1,4-butanediol on acid catalysts like heteropolyacids, 20,21 zeolites 22 and sulfonic acids. 23 The listed processes present some disadvantages, such as high cost and rapid deactivation of the catalyst, and the reaction required high pressure to be carried out.…”
