Definitions
- the present invention relates to a method for producing anhydrosugar alcohols using a hydroroll (i.e., a crystal mother liquor remaining after obtaining glucose crystals from a glucose stock solution), and more specifically, to converting a hydrogenated sugar to anhydrosugar alcohol by dehydration.
- a hydroroll i.e., a crystal mother liquor remaining after obtaining glucose crystals from a glucose stock solution
- the raw material cost can be relatively low compared to the use of high-purity raw material (eg, high-purity sorbitol)
- the present invention relates to a method for producing anhydrosugar alcohol which can be improved and can also reduce the amount of waste generated and processing cost in the production of glucose.
- Hydrogenated sugar means a compound obtained by adding hydrogen to a reducing end group of a saccharide, and generally HOCH 2 (CHOH) n CH 2 OH, where n is an integer of 2 to 5 ) And are classified according to carbon number to trititol, pentitol, hexitol and heptitol (4, 5, 6 and 7 carbon atoms, respectively).
- hexitol having 6 carbon atoms includes sorbitol, mannitol, iditol, galactitol and the like, and sorbitol and mannitol are particularly useful substances.
- Anhydrosugar alcohols have a diol form having two hydroxyl groups in the molecule, and may be prepared using hexitol derived from starch (eg, Korean Patent No. 10-1079518, Korean Patent Publication No. 10). -2012-0066904).
- Anhydrosugar alcohols have been studied for a long time with a great deal of interest in that they are environmentally friendly materials derived from renewable natural resources.
- isosorbide made from sorbitol has the widest range of industrial applications at present.
- anhydrosugar alcohols is very diverse, such as treatment of heart and vascular diseases, adhesives of patches, mouthwashes and the like, solvents of the composition in the cosmetic industry, emulsifiers in the food industry.
- it can also be used as an environmentally friendly solvent of adhesives, environmentally friendly plasticizers, biodegradable polymers, water-soluble lacquer.
- anhydrous sugar alcohol can be produced in a more economical manner.
- the development of technology is called for.
- the present invention has been made to solve the above-mentioned problems of the prior art, by utilizing the by-products or waste of the hydro-hydrol produced in the production of glucose as a raw material, it is possible to improve the economics, and also reduce the amount of waste generated and processing costs in the production of glucose. It is a technical problem to provide a manufacturing method of anhydrosugar alcohol.
- the present invention in the method for producing anhydrosugar alcohol comprising the step of dehydrating the hydrogenated sugar to anhydrosugar alcohol, the result of the hydrogenation of the hydro-reaction as at least part of the hydrogenated sugar It provides a method characterized by using.
- an equivalent level or more of anhydrosugar alcohol conversion can be obtained, thereby improving economic efficiency.
- it can also reduce the amount of waste generated and processing costs in the production of glucose.
- the method for producing anhydrosugar alcohols of the present invention is characterized by using the resultant product of hydrohydrating the hydrogenated sugar as the at least part of the hydrogenated sugar in dehydrating and converting the hydrogenated sugar into anhydrosugar alcohol.
- the hydrogenated sugar is generally called a sugar alcohol, and means a compound obtained by adding hydrogen to a reducing end group of the sugar.
- Hydrogenated sugars are classified according to carbon number into tetratritol, pentitol, hexitol and heptitol (4, 5, 6 and 7 carbon atoms, respectively).
- hexitol having 6 carbon atoms includes sorbitol, mannitol, iditol, galactitol and the like, and sorbitol and mannitol are particularly useful substances.
- anhydrosugar alcohol means any substance obtained by removing one or more water molecules from the original internal structure of the hydrogenated sugar in one or more steps in any manner.
