Abstract | Proposed are 2-Oxo-1,3-dioxolane-4-carboxylic acid and derivatives thereof, according to the following formula, in which R1 represents a negative charge, hydrogen or can be preferably Me or Et or an n-valent radical, which may be substituted with at most n-1 further 2-oxo-1,3-dioxo- lane-4-carboxyl groups, as well as a process for their preparation by means of carboxylation of the corresponding epoxides, a process for their transesterification and their use for the preparation of hydroxyurethanes and as end groups for the blocking of amines.
La présente invention concerne l'acide 2-Oxo-1,3-dioxolane-4-carboxylique et ses dérivés, leur préparation et leur utilisation. L'invention propose l'acide 2-Oxo-1,3-dioxolane-4-carboxylique et ses dérivés, conformément à la formule suivante, dans laquelle R1 représente une charge négative, de l'hydrogène ou peut être de préférence Me ou Et ou un radical n-valent, lequel peut être remplacé par au plus n-1 autres groupes 2-oxo-1,3-dioxolane-4-carboxyles, ainsi que le procédé permettant de les préparer au moyen de la carboxylation des époxydes correspondants, le procédé pour leur transestérification et leur utilisation pour la préparation d'hydroxyuréthanes et comme groupes terminaux pour le blocage des amines. |
