METHOD FOR EXTRACTING SUGAR CANE WAX COMPOSITION

摘要

PURPOSE:To extract the high-purity subject compound in high yield and excellent economic efficiency by adding ethanol to the residue in squeezing process of sugar cane and heating the residue under pressure, filtering the mixture and depositing crystals material from the filtrate. CONSTITUTION:Ethanol (preferably water-containing alcohol) is added to the residue obtained in squeezing process in producing sugar from cane wax so that alcohol concentration becomes >=50wt.% ZM, (preferably 70-90wt.%) and the mixture is heated to the boiling point or above (preferably 100-150 deg.C) of ethanol under pressure (preferably 2-5kg/cm<2>) and solid content is filtered in heating and crystals are deposited from the filtrate to extract the objective composition. Furthermore, the residue is preferably a filter cake obtained in cleaning process of sugar.
