Verbessertes Chloren von Sucrose-6-Ester
A process for the chlorination of sucrose-6-esters to produce 6 min ,4,1 min -trichlorosucrose-6-esters which comprises the steps of: (a) adding at least seven molar equivalents of an acid chloride to a reaction mixture containing a sucrose-6-ester and a tertiary amide to form initially a chloroform...
