Abstract
This invention specifically relates to a method for preparing γ-butyrolactone by hydrogenation of 1,4-butanediol coupled with dehydrogenation of succinic acid. This method couples the hydrogenation reaction of succinic acid with the dehydrogenation reaction of 1,4-butanediol to prepare γ-butyrolactone in high yield. The reaction process is simple, improves the heat and mass transfer efficiency of the catalyst surface, simplifies the operation steps, reduces energy consumption, and saves product separation costs. The highest yield of γ-butyrolactone can reach 99.9%, making it suitable for large-scale industrial production.
