Method of preparing alkanesulfonamides from alkanesulfonyl chlorides
Abstract
Abstract THE PRESENT INVENTION RELATES TO A METHOD OF PREPARING ALKANESULFONAMIDES FROM THE ALKANESULFONYL CHORIDE REACTION MXTURE OBTAINED BY THE SULFOCHLORINATION OF A PARAFFIN HYDROCARBON. THE ALKANESULFONYL CHLORIDE MIXTUR IS ADDED TO AN EXCESS OF A NITROGEN BASE COMPOUND SELECTED FROM THE GROUP CONSISTING OFAMMONIA AND AMINES TO FORM AN ALKANESULFONAMIDE PRODUCT MIXTURE. BY THE PRESENT INVENTION THE ALKANESULFONAMIDE PRODUCT MIXTURE IS HEATED TO A TEMPERATURE OF FROM ABOUT 20D*C. TO ABOUT 200*C. AT A PRESSURE OF FROM ABOUT 1 TO ABOUT 350 ATMOSPHERES FOR A PERIOD OF TIME SUFFICIENT TO CONVERT CHAIN CHLORINATED ALKANE SULFONAMIDE COMPOUNS CONTAINED IN THE PRODUCT MIXTURE TO AMINOALKANESULFONAMIDES. ONCE FORMED, THE AMINOALKANESULFONAMIDES MAY BE REMOVED FROM THE PRODUCT MIXTURE BY EXTRACTION.
