Abstract

Framgangsmåte for framstilling av ioheksol hvorved 5-acetamido-N,N'-bis(2,3-dihydroksypropyl)-2,4,6-triiodisoftalamid alkyleres ved bruk av 2(2-metoksy-etoksy)etanol som løsningsmiddel i nærvær av en base. Rå ioheksol isoleres valgfritt fra reaksjonsblandingen. Alkyleringsmidlet er fortrinnsvis l-klor-2,3-propandiol, og basen er et alkalimetallhydroksid, slik som natriumhydroksid eller kaliumhydroksid.
