UDK 543.42 Спектральный анализ
Fizicheskimi metodami analiza identificirovana struktura sintezirovannogo monoamida maleinovoy kisloty. Opredelena rastvorimost' monoamida maleinovoy kisloty v organicheskih rastvoritelyah, obladayuschih razlichnymi svoystvami i znacheniyami dielektricheskoy pronicaemosti. Vybrano sootnoshenie rastvoriteley, kotoroe pozvolyaet osuschestvit' analiz s nailuchshimi metrologicheskimi harakteristikami. Podtverzhdeno, chto reakciya mezhdu p-toluidinom i maleinovym angidridom s obrazovaniem (2z) 4-(metilanilino)-4-oksobut-2-enovoy kisloty protekaet s vysokim vyhodom, massovoy doley osnovnogo veschestva 94,23±0,69 %.
p-toluidin, maleinovyy angidrid, (2z)-4-(metilanilino)-4-oksobut-2-enovaya kislota, IK- i YaMR1N-spektroskopiya, potenciometricheskoe titrovanie, metrologicheskie harakteristiki
