Enantioenrichment by pervaporation

摘要: The present paper describes an original concept of membrane-assisted enantiomer enrichment exploiting a combination complexation to β-cyclodextrin and selective transport through PDMS pervaporation membrane. Linalool has been used as model racemic mixture, due its large use in perfumes, soaps detergents. Results, under different operating conditions such the feed composition temperature were presented. According these experiments, optimal range we considered, best enantiomeric achieved was 14% for linalool single pass permeate flux value obtained equal 250 g h−1 m−2. This result demonstrated that our approach offered opportunities enantiomers separation; performances may obviously be improved process extended two or even more stages.
