| titleOfInvention | A method of isolating opium alkaloids from opium |
| abstract | A method of isolating opaloid alkaloids, which isnis based on the known extraction of opium with water afternelevated temperature, thicken the extractnreduced (pressure, alkaline concentrate anorganicnbases, separation excludednalkaloid or crude extractnmorphine, extraction of this fraction with organicnwater-immiscible solventnseparating the insoluble phase and isolating the individualnalkaloids from the extract based onntheir different bases by conversion into saltnand free base and free base extractionnorganic solvent immisciblenwith water. The essence is that it isnwater extraction of opium is performed in the presenceninert filtering aids and knprocessing of alkaloids or crudenmorphine and to isolate individual alkaloidsnin free base form by extractionnis used as organic, with waternimmiscible solvent of toluene |
