Title (EN) PURIFICATION OF TERTIARY FORMAMIDE CONTAMINATED WITH TERTIARY ACETAMIDE
(FR) PURIFICATION D'UN FORMAMIDE TERTIAIRE CONTAMINÉ PAR UN ACÉTAMIDE TERTIAIRE
Abstract: front page image
(EN)A chlorinating agent such as a chloroiminium species is used to remove or neutralize tertiary acetamide present as a contaminant in a tertiary formamide solvent. Tertiary formamide solvent purified or treated in this manner can be used as a reaction vehicle for the chlorination of sucrose-6-acylates, thereby improving the yields of the desired sucralose-6-acylate (an intermediate in the production of sucralose).
(FR)Cette invention concerne un agent de chloration tel qu'un agent de l'espèce chloroiminium utilisé pour éliminer ou neutraliser un acétamide tertiaire présent sous forme de contaminant dans un solvant de formamide tertiaire. Le solvant de formamide tertiaire ainsi purifié ou traité peut être utilisé en tant que véhicule de réaction pour la chloration des saccharose-6-acylates, améliorant ainsi les rendements du sucralose-6-acylate recherché (un intermédiaire dans la production du sucralose).
