Title (EN) PROCESS FOR PRODUCING CHITIN DERIVATIVE
(FR) PROCEDE DE PRODUCTION D'UN DERIVE DE CHITINE
Abstract: front page image
(EN)A process for producing a chitin derivative having the high ability to asymmetrically identify; and a separatory agent for optical isomers which comprises the chitin derivative as an agent for asymmetric identification. The process for producing a chitin derivative is characterized by converting chitin into a derivative in a mixed solvent comprising lithium chloride and N,N-dimethylacetamide.
(FR)L'invention concerne un procédé de production d'un dérivé de chitine ayant une grande capacité à s'identifier asymétriquement, ainsi qu'un agent séparateur pour isomères optiques comprenant les dérivés de chitine en tant qu'agent d'identification asymétrique. Le procédé de production d'un dérivé de chitine est caractérisé par la transformation de chitine en un dérivé dans un solvant mixte contenant du chlorure de lithium et un N,N-diméthylacétamide.
