Filed: 1996-05-17
Granted: 2004-02-10
Abstract: A continuous process for producing levulinic acid from carbohydrate-containing materials in high yields is described. According to the process, a carbohydrate-containing material is supplied continuously to a first reactor and hydrolyzed at between 210° C and 230 °C for between 13 seconds and 25 seconds in the presence of between 1 36 and 5 36 by weight mineral acid.
