ADDUCT OF 9,10-DIISOQUINOLINIUM DIHYDROANTHRACENE DICHLORIDE WITH ISOQUINOLINE AS AN INHIBITOR OF STEEL CORROSION IN ACID MEDIUM Russian patent published in 1998 - IPC

Abstract SU 1504983 A1

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 C32H24N2Cl2•C9H7N•1,5H2O.. 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
