Title:
A recycling method of the ionic liquid used for the manufacturing method of cyclic ether, and it
Document Type and Number:
Japanese Patent JP6054716
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing cyclic ethers having a high environmental friendliness capable of obtaining, without using a supercritical fluid or high-pressure reaction vessel, cyclic ethers led by isosorbide in favorable yields within brief periods and a method for recycling an ionic liquid used for the same.SOLUTION: The provided method for manufacturing cyclic ethers comprises a step of dehydrating a polyhydric alcohol possessing at least three hydroxyl groups by heating the polyhydric alcohol with microwaves by using an ionic liquid as a reaction solvent. A method for recycling the ionic liquid used for the same is also provided.
