Title:
METHOD OF MANUFACTURING TETRAHYDROFURAN
Document Type and Number:
Japanese Patent JP2014166980
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an industrially advantageous method of manufacturing tetrahydrofuran from 1,4-butanediol by using an acid catalyst, which can suppress reduction of reaction rate and a production amount of a solid by-product, and stably achieve high productivity.SOLUTION: There is provided a method of manufacturing tetrahydrofuran having a water concentration in a reactor liquid phase of 1.4 to 10 wt.% by supplying 1,4-butanediol to a reaction vessel and conducting a cyclodehydration reaction in the presence of an acid catalyst.
