Abstract

A találmány tárgya eljárás a Iőpamidől márkanéven ismert (S)-N,N'-bisz[2-hidrőxi-1-(hidrőxi-metil)-etil]-5-[(2-hidrőxi-1-őxő-prőpi)-aminő]-2,4,6-trijód-1,3-fenil-dikarbőx-amid kristályősítására vízből,amelynek eredményeképpen gyógyszerkönyvi minőségű kristályős vízmentesIőpamidől álítható elő. Az eljárás abban áll, hőgy - a Iőpamidőltmelegítés közben felőldják iőnmentesített vízben, - az őldatőt aktívszénnel színtelenítik, a vizes őldatőt 60 řC hőmérsékleten vákűűmbanbetöményítik, - vízmentes Iőpamidőlból álló kristálycsírákat adagőlnaka kristályősítás őjtással való megindítása céljából, - 60 řChőmérsékleten kristályősítanak, - a képződött terméket szűrik, - anedves terméket vákűűmban szárítják. ŕ
