发明名称 CHROMATOGRAPHIC PROCESSES FOR RECOVERY OF ISOSORBIDE
摘要 The present invention provides a process which will allow recovery of high yields of pure isosorbide from crude reaction mixtures. More specifically, the instant invention demonstrates that isosorbide can be chromatographically separated to yield pure material, using commercial strong-acid cation exchange resins.
