Abstract
A process for the separation of sucrose from molasses and the unique adsorbent used to accomplish the separation. The adsorbent comprises a mixture of an ion retardation resin and a calcium and potassium cation exchanged nuclearly sulfonated styrene cation exchange resin having about 8% crosslinkage. In the process, the molasses feedstock is passed through a bed of the adsorbent and the sugar components, including sucrose, are eluted first and the mineral salts and betaine selectively retained. The retained components may be desorbed with water.

A process for the separation of sucrose from molasses feedstock through a bed of adsorbent comprising a mixture of an ion retardation resin and a calcium and potassium ion exchanged nuclearly sulfonated styrene cation exchanged resin having about 8% crosslinkage, said adsorbent having a higher relative selectivity for mineral salts and betaine components of said feedstock than for sucrose, adsorbing said mineral salts and betaine components in said adsorbent bed and removing a product stream comprising sucrose from said adsorbent bed.
An adsorbent useful for the separation of sucrose from molasses comprising a mixture of an ion retardation resin and a calcium and potassium ion exchanged nuclearly sulfonated styrene cation exchange resin having about 8% crosslinkage.
