Document Type and Number:
WIPO Patent Application WO2007099557
Kind Code:
B1
Abstract:
A process for controlling the emission of gaseous by-products in the preparation of a Vilsmeier reagent, and its use as a chlorinating reagent in the production of high intensity sweeteners, such as trichlorogalactosucrose, from partially protected sugars.
