METHOD FOR PRODUCING 1,3-ALKANEDIOL FROM 3-HYDROXYESTER COMPOUND |
摘要 |
PURPOSE: Provided is a method for producing 1,3-alkanediol from 3-hydroxyester compound, which can increase the selectivity of 1,3-alkanediol by 90% or more, and improve the stability of catalyst. CONSTITUTION: The method comprises the steps of (i) adding an alkaline precipitating agent to aqueous copper solution to form a particle, adding a colloidal silica to the solution and aging the solution to form a catalyst, (ii) activating the formed catalyst by reducing the catalyst in the presence of activating solvent at 100-250 deg.C by using hydrogen gas or mixed hydrogen/nitrogen gas having pressure of 5-2000 psig and activating the, and (iii) hydrogenating 3-hydroxyester compound at 100-250 deg.C by using hydrogen gas or mixed hydrogen/nitrogen gas in the presence of the activated catalyst and reaction solvent by an liquid slurry method .
