NON-AQUEOUS PROCESS FOR REACTING SULTONES WITH CELLULOSIC MATERIALS AND THE PRODUCT PRODUCED

Cellulose is converted into sodium cellulosate by reaction of the preswollen cellulose with sodium alkoxide and then washed with tertiary butanol prior to reaction with hydrocarbon sultone in tertiary butanol. More sulfur is added by this procedure than when water is present. The sultone solution is...

Zusammenfassung:	Cellulose is converted into sodium cellulosate by reaction of the preswollen cellulose with sodium alkoxide and then washed with tertiary butanol prior to reaction with hydrocarbon sultone in tertiary butanol. More sulfur is added by this procedure than when water is present. The sultone solution is not contaminated by base and may be used repeatedly. This reuse of reactants reduces costs and diminishes pollution. The resultant products have active acidic sites, thus making them suitable intermediates for other reactions.
