Metoda z antranilno kislino






V bučki z okroglim dnom smo zmešali 7 g antranilne kisline, 5 ml o-toluidina in 4 ml ledocetne kisline. Mešanici smo počasi dodali 40-50 g polifosforne kisline in jo 20-30 minut segrevali na 140-160 °C. Nato smo jo 10 minut segrevali na 180 °C, ohladili in prelili v 150-200 ml vode ter nevtralizirali z 20 % raztopino Na2CO3. Metanol se je dodajal, dokler se v raztopini ni pojavila dolgotrajna motnost, po eni uri pa se je oboril metakvalon v obliki proste baze, ki se je na ta način še enkrat rekristaliziral. Izplen 55 %.

Ko navajate "polifosforna kislina", o kateri konkretno govorite? Ali imate v mislih ortofosforno kislino ali tripolifosforno kislino ali kakšno drugo kislino?
