Jan 02 2007 Solvent‐Free Asymmetric Anhydride Opening in a Ball Mill. Solvent‐Free Asymmetric Anhydride Opening in a Ball Mill. Rantanen Toni; Schiffers Ingo; Bolm Carsten 2007-01-02 00:00:00 ChemInform Abstract The desymmetrization of meso‐anhydrides proceeds smoothly under solvent‐free conditions when the reactants anhydride alcohol and quinidine as mediator are mixed in a ball mill.
Jan 23 2018 The latter is formed by ball mill grinding as two different polymorphs Form A and Form B. The ratio R Form B Form A Form B at milling equilibrium depends on the nature and concentration of the solvent in the milling jar.

Spontaneously following the addition of water miscible organic solvent to an aqueous phase. Figure 1. Schematic view of spontaneous formation of drug microparticles via solvent displacement method. Mechanical disruption is a common size reduction technique; planetary ball mill is
The effect of wet grinding is better than dry grinding It is believed to be more efficient to get smaller particles as the liquid helps to lower the surface energy of particles. Any solvent which do not react with your material and jars and balls can be used. People ofen use ethanol toluene and acetone. Previous: How to retrieve the powders from the ball after ball milling?
The mechanochemical technique of ball milling has been applied to the asymmetric opening of meso -anhydrides mediated by the cinchona alkaloid quinidine. A simple workup procedure affords the products optically active dicarboxylic acid monoesters in high yields with up to 64 ee. With most substrates no column chromatography was needed.
