AMORPHOUS CALCIUM PHOSPHATE CATALYST USED FOR PREPARING 1,3-BUTADIENE AND METHYL ETHYL KETONE FROM 2,3-BUTANEDIOL AND PREPARATION METHOD OF AMORPHOUS CALCIUM PHOSPHATE

摘要

According to an embodiment of the present invention, disclosed are an amorphous calcium phosphate catalyst used for preparing 1,3-butadiene and methyl ethyl ketone from 2,3-butanediol, a preparation method of the catalyst, and a method for preparing 1,3-butadiene and methyl ethyl ketone from 2,3-butanediol. The preparation method of the amorphous calcium phosphate catalyst comprises the steps of: (a) preparing a phosphoric acid alkaline aqueous solution by conducting a reaction between a solution containing phosphoric acid and alkali; (b) preparing a calcium phosphate slurry by adding a calcium precursor aqueous solution to the phosphoric acid alkaline aqueous solution; and (c) obtaining an amorphous calcium phosphate catalyst by heat-treating the slurry.;COPYRIGHT KIPO 2016
