Abstract
Inventia de fata se refera la un procedeu de obtinere a etilsuccinatului de eritromicina prin acilarea solutiei de eritromicina în clorura de metilen sau cloroform, cu clorura de monoetil succinil sub forma de solutie în solventii mentionati mai sus,în prezenta de bicarbonat de sodiu la un raport de 2,5....3,5 moli/moli de clorura acida, la temperatura de 0...27 degree C, se izoleaza produsul de reactie prin filtrarea precipitatului rezultat, care apoi se suspenda în apa rece în cantitate de 1 g la 15 ...30 ml, se filtreaza suspensia si se usuca la presiune redusa, la temperatura de 20...30 degree C. Procedeul este simplu si permite utilizarea etilsuccinatului de eritromicina pentru uz farmaceutic.
