Abstract: The disclosure relates to a method for producing levulinic acid in a molten salt hydrate from cellulose hydrolysis. An inorganic molten salt hydrate was prepared by mixing an inorganic salt with water, cellulose is added and stirred to dissolve, a solid catalyst is added and heated up for reaction to obtain a reactant, the reactant is cooled and subjected to a separation to obtain the levulinic acid, and the inorganic molten salt hydrate and the solid catalyst obtained after the separation are recycled, wherein the inorganic salt is one or more selected from the group consisting of LiCl, LiBr, CaBr2, Ca(NO3)2, LiNO3 and KNO3.
