Zusammenfassung:	The present disclosure relates to a process for isolating S-isomer crystals of Indoxacarb having purity in the range of 98% to 99%. The raw material is crude Indoxacarb comprising impurities in an amount in the range of 3 wt.% to 15 wt.%. The process of the present 5 disclosure is simple, economical, and gives S-isomer crystals of Indoxacarb which is the active isomer having insecticidal activity. La présente invention concerne un procédé d'isolement de cristaux d'isomère S d'indoxacarb ayant une pureté dans la plage de 98 % à 99 %. La matière première est de l'indoxacarb brut comprenant des impuretés en une quantité dans la plage de 3 % en poids à 15 % en poids. Le procédé de la présente invention est simple, économique et donne des cristaux d'isomères S d'indoxacarb qui est l'isomère actif ayant une activité insecticide.
