Continuous Production Method of 1,2,4-Butanetriol

摘要

The present invention relates to a continuous method of producing 1,2,4- butane triol , at least 3 nickel catalyst is supplied to the liquid mixture consisting of 2,3- epoxy -1,4- butanediol , and a solvent in a fixed bed continuous reaction system is filled with a metal surface area of / g, reaction in the temperature 10~250 under a hydrogen gas atmosphere , 5 to 300 atm and a reaction pressure of 0.1~30 hr ^-1 continuously hydrogenolysis under the reaction conditions of the weight space velocity (LHSV) of the step characterized in that it comprises a to carry out the reaction . The present invention is high in productivity over the prior art , environmentally friendly, has the advantage that can be produced in a cost-effective way to come 1,2,4 butanetricarboxylic .
