摘要:The present invention relates to the industrial preparation of non-ionic X-ray contrast agents. In particular, it relates to a process for the synthesis of lopamidol using a reactive extrusion process in continuous which enable an efficient conversion of the relevant key intermediates, preferably in the absence of any solvent. The invention further relates to the preparation of radiographic X-rays contrast agents or key intermediates thereof by exploiting the technology of reactive extrusion.

权利人:ROITMAN LIPA L
摘要:A process for the synthesis of novel compounds is described comprising reacting tetrachloroethylene with substances containing active methylene group in the presence of free radical initiators. Also, a process for grafting tetrachloroethylene is described comprising reacting these compounds with polymers containing active methylene group in the presence of free radical initiators. Furthermore, a method of conducting such reactions to high conversion is described, comprising conducting the reactions in the reflux condensate. The present invention provides a novel and high yield route for heretofore unobtainable materials.
