Beschreibung
Zusammenfassung:	FIELD: organic chemistry. SUBSTANCE: invention relates to heterocyclic compounds, in part, adduct of 9,10-diisoquinolinium dihydroanthracene dichloride with isoquinolines. Synthesis of the end compound is carried out by reaction of 9,10-dichlorodihydroanthracene with isoquinoline at 80-90 C for 1 h. The yield is 88%, m. p. is 240-242 C, empirical formula is CHNClCHN1,5HO.. Inhibitory activity of new substance exceeds activity of industrial inhibitor ЧМ. by 3-fold. The synthesized compound can be used for industrial fittings protection. EFFECT: improved synthesis, increased yield, enhanced effectiveness. 1 tbl Изобретение касается гетероциклических соединений, в частности аддукта 9,10-диизохинолинийдигидроантрацендихлорида с изохинолинами - ингибитора коррозии стали в кислой среде, и может быть использовано в промышленности для защиты арматуры. Цель - создание более эффективных ингибиторов этого класса. Синтез целевого соединения ведут реакцией 9,10-дихлордигидроантрацена с изохинолином при 80-90C (1 ч). Выход 88%; т.пл. 240-242C, брутто-формула CHNCl* CHN * 1,5HO. Новое вещество по ингибирующей активности в 3 раза превышает промышленный ингибитор ЧМ. 1 табл.
