| titleOfInvention | Method for preparing gamma butyrolactone from 1,4-butanediol |
| abstract | The present invention relates to a method for preparing 1,4-butanediol as gamma butyrolactone using a catalyst of formula (1) or (2).n n n [Formula 1]n n n n n n n n In Formula 1, M is at least one selected from metal elements or quasi-metal elements except Cu and Ga, a: b: c is from 1: 0.01 to 15: 0 to 10, x is each component The stoichiometric value of depends on the valence and composition ratio.n n n More specifically, in the method of preparing gamma butyrolactone by gas phase dehydrogenation of 1,4-butanediol at a reaction temperature of 150 to 300 ° C. and a reaction pressure of 0 to 10 kg / cm 2 G in the presence of the catalyst of Formula 1 It is about.n n n 1,4-butanediol, gamma butyrolactone, copper, gallium, catalysts, metals or metalloids |
