Stirring a suspension of cellulose in an alcohol containing an acid catalyst at 150-200°C for a short time produces a significant yield of the α and β alkyl glucosides. The dialkyl ether, the alkyl levulinate, and furfurals are also produced to a lesser extent. The products of several different alcohols (isopropyl, hexyl, octyl) were studied. The effects of specific acid, acid concentration, temperature, time, added salts, and added water on yields of the various products were also examined. Facile interconversion of the α and β forms of glucose makes purification by crystallization difficult, but the α and β forms of glucosides do not readily interconvert. This offers the possibility of obtaining a highly pure glucoside that can be conveniently converted to pure glucose.
