Abstract
Przedmiotem zgłoszenia jest rozpuszczalny w wodzie kwas 2,9-dimetylo-1,10-fenantrolino-4-ditiokarboksylowy 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, tetrahydrofuran w ilości niezbędnej do rozpuszczenia 2,9-dimetylo-1,10-fenantroliny, roztwór tert-butylolitu w węglowodorze wybranym spośród: pentan, heksan lub heptan, w stosunku molowym tert-butylolitu względem 2,9-dimetylo-1,10-fenantroliny wynoszącym ≥ 1,4 do 1,0, disiarczek węgla w stosunku molowym wynoszącym ≥ 1,5 do 1,0 względem 2,9-dimetylo-1,10-fenantroliny, przy czym disiarczek węgla zawsze dodaje się jako ostatni, kontrolując by temperatura środowiska reakcji na etapie dodawania roztworu tert-butylolitu, a następnie disiarczku węgla wynosiła -78°C ± 10%, po czym otrzymaną mieszaninę ogrzewa się przez co najmniej trzy godziny w temperaturze od 15°C do 45°C, przy czym dotychczasowe etapy realizuje się w atmosferze gazu obojętnego, po czym lotne składniki mieszaniny reakcyjnej oddestylowuje się, następnie suchą pozostałość zakwasza się dodając wodny roztwór kwasu, w ilości niezbędnej do uzyskania odczynu kwasowego roztworu i odfiltrowuje się surowy produkt, przy czym reakcję prowadzi się ciągle mieszając reagenty.The subject of the application is a water-soluble 2,9-dimethyl-1,10-phenanthroline-4-dithiocarboxylic acid with a chemical structure presented by formula 2 and a method for its preparation, which comprises introducing into a reactor: 2,9-dimethyl-1,10-phenanthroline of formula 1, tetrahydrofuran in an amount necessary to dissolve 2,9-dimethyl-1,10-phenanthroline, a solution of tert-butyllithium in a hydrocarbon selected from: pentane, hexane or heptane, in a molar ratio of tert-butyllithium to 2,9-dimethyl-1,10-phenanthroline of ≥ 1.4 to 1.0, carbon disulfide in a molar ratio of ≥ 1.5 to 1.0 to 2,9-dimethyl-1,10-phenanthroline, wherein carbon disulfide is always added The reaction mixture is added last, ensuring that the temperature of the reaction medium at the stage of adding the tert-butyllithium solution and then carbon disulfide is -78°C ± 10%, after which the mixture obtained is heated for at least three hours at a temperature from 15°C to 45°C, with the previous steps being carried out in an inert gas atmosphere, after which the volatile components of the reaction mixture are distilled off, then the dry residue is acidified by adding an aqueous acid solution in an amount necessary to obtain an acidic solution and the crude product is filtered, the reaction is carried out with continuous stirring of the reagents.
