With a fully functioning setup we focused our attention on studying SDE by sublimation phenomena, specifically concentrating on the case of a-(trifluoromethyl)lactic acid. Scalemic mixtures of TLA have been investigated experimentally and theoretically for their tendency to spontaneously disproportionate at room temperature by sublimation. In this manner, the remaining sample of TLA can enrich an enantiomer, and, in the long run, reach enantiopurity.
