MANUFACTURING METHOD OF 1,3-BUTADIENE FROM 2,3-BUTANDIOL CAPABLE OF MANUFACTURING 1,3-BUTADIENE WITH EXCELLENT SELECTIVITY FROM 2,3-BUTANDIOLS WHICH IS A BIO-PLATFORM COMPOUND
MANUFACTURING METHOD OF 1,3-BUTADIENE FROM 2,3-BUTANDIOL CAPABLE OF MANUFACTURING 1,3-BUTADIENE WITH EXCELLENT SELECTIVITY FROM 2,3-BUTANDIOLS WHICH IS A BIO-PLATFORM COMPOUND
PURPOSE: A manufacturing method of 1,3-butadiene is provided to obtain 1,3-butadiene with high selectivity through a dehydration of 2,3-butandiol, and to able to manufacture 1,3-butadiene at low temperature with long term stability.;CONSTITUTION: A manufacturing method of 1,3-butadiene comprises a step of manufacturing 1,3-butadiene from 2,3-butanediol under the presence of a hydroxyapatite-alumina catalyst. The catalyst contains 5-40 weight% of alumina and 60-95 weight% of hydroxyapatite. The 1,3-butadiene is manufactured through a dehydration of the 2,3-butandiols. The dehydration is conducted under conditions of a reaction temperature of 320-430 C, a reaction pressure of 1-6 atm, and a liquid hour space velocity of 0.3-1.5 h^(-1).;COPYRIGHT KIPO 2013
