Method for producing r-butyrolactone |
| abstract |
The present invention is a method of producing a gamma-butyrolactone by hydrogenated catalytic reaction of maleic anhydride or succinic anhydride using a catalyst containing nickel or cobalt as a main component, wherein the halogen compound together with the reactants in the reaction system is 0.0001 to It relates to a method for producing gamma-butyrolactone, characterized by reacting by supplying 1.0 weight.n n n The method of the present invention is a method for producing gamma-butyrolactone by hydrogenation of maleic anhydride or succinic anhydride, by supplying a halogen compound of 0.1 wt. Or less to the reactant to prevent the overhydrogenation reaction in the hydrogenation reaction. It has the effect of producing gamma-butyrolactone in high yield by inhibiting the production of by-products such as panic acid or butanoic acid. |
