In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Recommanded Product: 4865-84-3, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 4865-84-3, name is 1,2-Benzisoxazole-3-acetic Acid. In an article£¬Which mentioned a new discovery about 4865-84-3
A PROCESS FOR THE MANUFACTURE OF ZONISAMIDE
The present invention describes an improved process for the preparation of 1,2Benzisoxazole-3-methanesulphonamide (Zonisamide), a well known anti-epileptic agent which possesses anti-convulsant and anti-neurotoxic effects. Other aspect of this invention are isolation of a key intermediate, viz., crystalline sodium chloride associated 1,2Benzisoxazole-3-methane sodium sulfonate (BOS-Na:NaCl). The isolated crude BOSNa:NaCl is directly converted to Zonisamide using controlled molar ratio of chlorosulfonic acid to avoid the disulfonated side products. The analytical characteristics like IR and XRD data of the BOS-Na:NaCl are also reported to confirm its nature.
