Abstract
Inventia se refera la un procedeu de obtinere a 8-hidroxichinolatului de cupru prin reactia dintre ortoaminofenol, ortonitrofenol si glicerina, în prezenta de acid sulfuric concentrat, în raport molar de 1:1,1:2,3:2,9, cantitatea de acid sulfuric introdusa în doua etape, astfel ca temperatura finala sa nu depaseasca 140-145 degree C, neutralizarea amestecului de reactie cu alcalii la pH=3,5 filtrarea rasinilor formate, tratarea, dupa purificarea, a 8-hidroxichinolinei obtinute cu solutie apoasa de sulfat de cupru, neutralizarea amestecului de reactie cu solutie de amoniac 12-13% si uscarea produsului filtrat, în care, în scopul cretterii randamentului la 95-96%, purificarea 8-hidroxichinolinei se realizeaza printr-o nota preciputare a produsului secundare de reactie cu solutie de amoniac 12-13%, la pH 4,2-4,5 si temperatura de 70-80 degree C, cînd se separa si restul de rasini, 8-hidroxichinolina purificata, sun forma de solutie rezultata dupa filtrare, fiind tratata ca atare cu solutie apoasa de sulfat de cupru.
