Single nickel source in situ fabrication of a stable homochiral MOF membrane with chiral resolution properties

A homochiral MOF membrane was successfully and facilely synthesized using an in situ growth method, which had the advantages of cheap raw materials, simple operation and high thermal stability. A diol isomer mixture was used to test the separation efficiency of the membrane at different temperatures and pressures.

Resolution of Racemic Mixtures via Lipase Catalysis in Organic Solvents

Yeast lipase and porcine pancreatic lipase have been found to vigorously function in nearly anhydrous organic solvents and catalyze the reactions of esterification and transesterification, respectively, in highly stereoselective manner.With use of these enzymatic processes, a number of optically active alcohols, carboxylic acids, and their esters have been prepared on a gram scale.
