Abstract
Przedmiotem wynalazku jest rozpuszczalny w wodzie kwas 9-metylo-1,10-fenantrolino-2-karboksylowy o budowie chemicznej przedstawionej wzorem 2 oraz sposób jego otrzymywania polegający na tym, że do reaktora wprowadza się 2,9-dimetylo-1,10-fenantrolinę o wzorze 1, chloryn sodu (NaClO2) w nadmiarze molowym, oraz wodę jako środowisko reakcji w ilości niezbędnej do rozpuszczenia chlorynu sodu, w dowolnej kolejności dodawania reagentów, po czym otrzymaną mieszaninę ogrzewa się w temperaturze nie niższej niż 90°C, korzystnie w temperaturze wrzenia mieszaniny reakcyjnej, do momentu zaniku widocznej w mieszaninie 2,9-dimetylo-1,10-fenantroliny, to jest do momentu zaniku osadu lub zawiesiny, po czym mieszaninę reakcyjną ochładza się do temperatury pokojowej, a otrzymany klarowny roztwór zakwasza się do pH lekko kwaśnego, korzystnie do pH od 2,8 do 3,4 poprzez dodanie wodnego roztworu kwasu, korzystnie HCl, przy czym korzystnie początkowo reakcję prowadzi się w temperaturze pokojowej i stopniowo podwyższa się ją do ostatecznej temperatury ogrzewania mieszaniny reagentów.The subject of the invention is water-soluble 9-methyl-1,10-phenanthroline-2-carboxylic acid with the chemical structure shown in formula 2 and the method of its preparation, consisting in introducing 2,9-dimethyl-1,10-phenanthroline into the reactor of the formula 1, sodium chlorite (NaClO2) in molar excess, and water as the reaction medium in the amount necessary to dissolve the sodium chlorite, in any order of adding the reagents, then the obtained mixture is heated at a temperature not lower than 90 ° C, preferably at a temperature boiling of the reaction mixture until the disappearance of the 2,9-dimethyl-1,10-phenanthroline visible in the mixture, i.e. until the disappearance of the precipitate or suspension, then the reaction mixture is cooled to room temperature, and the obtained clear solution is slightly acidified to pH acid, preferably to a pH of 2.8 to 3.4 by adding an aqueous acid solution, preferably HCl, preferably initially at room temperature and gradually it is brought up to the final heating temperature of the reactant mixture.
