Título (EN) METHOD FOR PREPARING ASYMMETRIC LINEAR CARBONATE
(FR) PROCEDE POUR PREPARER UN CARBONATE LINEAIRE ASYMETRIQUE
Resumo: front page image
(EN)A method for preparing asymmetric linear carbonate useful as an electrolyte for lithium secondary battery is disclosed. The method comprises the steps of: carrying out transesterification of symmetric linear carbonate with linear ester compound in the presence of a basic catalyst; and separating asymmetric linear carbonate from the transesterification product. Preferably, the linear ester compound is acetate compound.
(FR)L’invention décrit un procédé pour préparer un carbonate linéaire asymétrique utile en tant qu'électrolyte pour une batterie secondaire au lithium. Le procédé comprend les étapes consistant à : effectuer une transestérification du carbonate linéaire asymétrique avec un composé ester linéaire en présence d’un catalyseur basique ; et séparer le carbonate linéaire asymétrique du produit de la transestérification. Le composé ester linéaire est de préférence un composé acétate.
