Title: ITERATIVE REACTIVE DISTILLATION OF DYNAMIC ESTER MIXTURES
Abstract:
An iterative method of performing a reactive distillation of dynamic ester libraries containing nxm (m≤n) components, to reduce such mixtures to n pure ester species. The distillation occurs under anhydrous conditions, using metal alkoxide catalysts. Vacuum distillation of the mixture then isolates the most volatile ester at the expense of other (2n-2) compounds. The volatile ester is removed, and the process repeated with progressively less volatile ester species, yielding high purities and greater than 70% yields.
