ABSTRACT:
Various sugars and particularly sucrose may be separated from mixtures of sugars including glucose, fructose, raffinose, etc. by treating an aqueous solution of the sugar source containing these sugars with an adsorbent which will selectively adsorb sucrose thereon. Thereafter the sucrose may be desorbed from the adsorbent by treatment with a desorbent material. In the process of the present invention the adsorbent will comprise a shaped replicate of a particle aggregate comprising a carbonaceous pyropolymer containing recurring units of at least carbon and hydrogen atoms while the desorbent material will comprise an aqueous alcoholic solution. The preferred alcohols contain methanol and ethanol and will be present in the aqueous alcoholic solution in an amount in the range of from about 10% to about 50% by weight.
