Abstract:
1. A method for the chlorination of a sucrose-6-acylate to produce a 4,1′,6′-trichloro-4,1′,6′-trideoxy-galactosucrose-6-acylate wherein said method comprises: reacting the sucrose-6-acylate with a chlorinating agent in a reaction vehicle comprising a tertiary amide in order to chlorinate the 4, 1′ and 6′ positions of the sucrose-6-acylate; and (ii) quenching the product stream of (i) to produce a 4,1′,6′-trichloro-4,1′,6′-trideoxy-galactosucrose-6-acylate; wherein before said quenching, a portion of the tertiary amide is removed.
