标题:Design Of An Integrated Process Of Chromatography,Crystallization And Racemization For The Resolution Of 2',6'-Pipecoloxylidide (Ppx)
摘要:An Integrated Process For The Chiral Separation Of The Industrially Relevant Substance 2',6'-Pipecoloxylidide (Ppx),An Intermediate In The Manufacture Of A Number Of Anesthetics,Was Developed. By Combining Three Different Techniques,Chromatography,Crystallization,And Racemization,High Productivity Was Achieved. All Unit Operations Were Executed Using A Common Solvent System,Full Recycling,And A Minimum Of Solvent Exchanges Or Removals. The Target Molecule Was Obtained With An Enantiopurity Of >99.5 Wt %.
