Abstract
Procedeu de obtinere a meticilinei prin clorurarea acidului 2,6-dimetoxibenzoic si tratarea cu acid 6-aminopenocilinic, caracterizat prin aceea ca realizeaza clorurarea acidului 2,6-dimetoxibenzoic într-un amestec firmat dintr-un solvent organic potrivit, de preferinta hidrocarburi halogenate cu 1...2 atomi de carbon, ca, de exemplu, clorura de metilen, cloroform si dicloretan cu clorurua de tionil, la temperatura de 10...20 degree C, îndepartarea excesului de clorura de tionil prin distilare si dizolvarea clorurii acide rezultate într-o hidrocarbura alifatica halogentaa, ca, de exemplu, cloroform, clorura de metilen, dicloretan, de preferinta clorura de metilen, dupa acilarea acidului 6-aminopenicilanic cu clorura acidului 2,6-dimetoxibenzoic obtinuta, se efectueaza extractia acida a meticilinei la pH= 1,3...1,7 si apoi precipitarea meticilinei prin adaugarea, în proportie de 60% fata de volum organic, a unui amestec format din 3/5 acetat de butil si 2/5 acetona, dupa care se realizeaza precipitarea meticilinei sub forma de sare de sodiu prin tratarea cu solutie de 2-etilhexanoat de sodiu în izopropanol cu concentratie de 35%.
