Method for preparing an anhydrosugar alcohol using hydrol |
摘要 |
The present invention relates to a method for preparing an anhydrosugar alcohol using hydrol (namely, a crystalline mother liquor remaining after obtaining crystalline glucose from a crude glucose liquor). More particularly, the present invention relates to a method for preparing an anhydrosugar alcohol in a method for performing a dehydration reaction on the hydrogenated sugar so as to convert the hydrogenated sugar to an anhydrosugar alcohol, wherein the method for preparing an anhydrosugar alcohol is configured to use, as at least a portion of the hydrogenated sugar, the product obtained from the hydrogenation of the hydrol which is a by-product or waste generated during the production of glucose, thus relatively lowering the cost for a material as compared with a case of using a high purity raw material (for example, high purity sorbitol), to thus improve economical advantages, and further reduce the amount of waste and cost for disposal of the waste during the production of glucose. |
