COMPOSITIONS OF ENANTIOMERIC DIACYL TARTARIC ANHYDRIDES AND PREPARATION THEREOF. |
摘要 |
<p>The present invention relates to compositions comprising mixtures of two enantiomeric forms of diacyl tartaric anhydride and mixtures obtainable by reacting an organic compound with a mixture comprising two enantiomeric forms of diacyl tartaric anhydride. The invention also relates to a method for the preparation of such enantiomeric mixtures, starting from a mixture comprising D-tartaric acid and L-tartaric acid. The method involves reacting tartaric acid with a fatty acid anhydride under dielectric heating conditions.</p> |
