摘要： In a process for preparing monoanhydrohexitols, 1,4-3,6-anhydrohexitols, 3,6-anhydrohexonolactones, and 3,6-anhydrohexoses from a starting product which is, respectively, a hexitol, a hexonolactone, or a hexose, or a polysaccharide containing such monosaccharide units, said starting product is reacted in liquid hydrogen fluoride with at least a carbocylic acid or an anhydride or a corresponding acid halide at a temperature below 50°C. A process for preparing alkyl-3,6-anhydrohexosides in which, in addition, an alcohol is reacted is also described. The products obtained are suitable for use in the preparation of surface active agents, emulsifiers, plasticizers or pharmaceutical carriers.
