| titleOfInvention | PROCEDURE FOR OBTAINING NEW ACILCEFALOSPORINS. |
| abstract | "PROCEDURE FOR OBTAINING NEW ACILEFALOSPORINS", characterized essentially because it consists of separately obtaining 7-ACA, 7-ADCA, cephalexin and substituted 7-ACA-3 acids, dissolving them or suspending them in an aqueous or organic aqueous medium, adding an ion scavenger hydrogen to react the set with acrylic acids -3- substituted in their reactive forms, the reaction temperature being between -30 and 70ยบ C while its duration is a function of the permanence of the reagents, making the control of the course of the reaction by conventional means until a basic solution is obtained which is acidified with inorganic acids and finally extracted with an organic solvent from which the final product is isolated by evaporation.
