| Abstract: | Glucurolactone is an effective drug for protecting liver.However,the processes of glucurolactone prepared from starch bring a mass of waste liquid at the same time,which pollute the environment seriously.The method,to produce levulinic acid from glucurolactone waste liquid,was studied and optimized for the technologic condition.The results show that levulinic acid can be obtained through hydrolyze the waste liquid aroused from producting process of glucurolactone under acid condition,followed concentration,... |
