| titleOfInvention | Method for producing highly pure anhydrosugar alcohols with improved yield by using redistillate of waste generated from crystallization procedure |
| abstract | The present invention relates to a process for preparing anhydrosugar alcohol from a hydrogenated sugar as a raw material, and more particularly, to a process for producing anhydrosugar alcohol by converting anhydride sugar (for example, hexitol) A method for producing a high purity, free alcohol without distillation by distilling a liquid resulting from the conversion reaction and crystallizing the resulting liquid in a solvent, the method comprising: removing a crystallization solvent from a crystallization mother liquor generated in a crystallization step, (1) introducing the distillate into a distillation stage of the liquid resulting from the conversion reaction, (2) introducing the distillate into a crystallization stage of the distillation result liquid, (3) independently recrystallizing the same, (4) immediately after completion of the purification step, the total yield of alcohol-free alcohol can be improved, and further, the amount of waste generated and the cost of treatment can be reduced There, low cost, to a technique capable of producing the anhydrosugar alcohol of high purity with high efficiency. |
