description	The present invention provides a process for the preparation of a non-ionic 5-(N-2, 3-dihydroxypropyl -acylamino)-2,4, 6-triiodo-N,N'-disubstituted -isophthalamide which process comprises reacting a non-ionic 5-acylamino-2, 4,6-triiodo-N, N'-disubstituted -isophthalamide with an oxirane in a solvent and in the presence of up to 7 mole percent of a strong base. Cette invention se rapporte à un procédé servant à préparer un 5-(N-2, 3-dihydroxypropyl -acylamino)-2,4, 6-tri-iodo-N,N'-disubstitué -isophtalamide non ionique, ce procédé consistant à faire réagir un 5-acylamino-2, 4,6-tri-iodo-N, N'-disubstitué -isophtalamide non ionique avec un oxirane dans un solvant et en présence d'une base forte dans une proportion maximum de 7 % en mole.
