RECOVERY OF DIMETHYLFORMAMIDE AND OTHER SOLVENTS FROM PROCESS STREAMS OF MANUFACTURE OF TRICHLOROGALACTOSUCROSE

摘要

This invention comprises an improved process for recovery and purification of DMF from an aqueous process stream containing DMF with or without inorganic impurities, particularly from process stream of a process of manufacture of the high intensity sweetener Trichlorogalactosucrose, by adsorption on an adsorbent having selective affinity towards dimethylformamide, followed by elution in pure form by eluting by an appropriate eluent, including methanol.
