FIELD: chemistry. ^ SUBSTANCE: invention relates to method of obtaining ,ë-bis-(1,5,3-dithiazepinan-3-yl)-alkanes, which can be applied as antibacterial, antifungal and antiviral agents, as biologically active complexing agents, selective sorbents and extractants of precious metals, special reagents for suppression of vital activity of bacteria in various technical media (from light industry to oil). Essence of method lies in interaction of ,ë-alkanediamine with 1,3,6-oxadithiapinane in presence of catalyst SmCl36H2O with mole ratio ,ë-alkanediamine : 1,3,6-oxadithiapinane : SmCl36H2O=10:20:(0.3-0.7) at temperature ~20C and atmospheric pressure for 2.5-3.5 h. Output of ,ë-bis-(1,5,3-dithiazepinan-3-yl)-alkanes (1) constitutes 72-85%. ^ EFFECT: increase of compound application efficiency. ^ 1 tbl, 1 ex |
