Abstract
The present disclosure provides a method for producing tetrahydrofuran (THF). The method includes: feeding 1,4-butanediol into a reactive distillation apparatus; performing the dehydration reaction in the presence of an acidic catalyst; and producing the top stream containing product THF and the bottom stream from the reactive distillation apparatus, wherein a weight ratio of a water content in the bottom stream to a water content in the top stream is 0.05 to 2.4, thereby providing a high conversion rate and more cost-effectiveness, and enhancing the value of the industrial application.
