Viscosity Behaviour of Substituted Benzo-1,3,6- Thiadiazepines in Different Percentages of Solvents

Abstract

The viscosities and densities of benzo-(4,5-d)-2,7-diphenylimino-
1,3,6-thiadiazepine (I), benzo-( 4,5-d)-2, 7-di-o-tolylimino-
1,3,6-thiadiazepine (II), benzo-(4,5-d)-2,7-di-m-tolylimino- 1,3,6-
thiadiazepine (III), benzo-( 4,5-d)-2,7-di-p-tolylimino-1,3,6-thiadiazepine
(IV), benzo-(4,5-d)-2,7-di-o-chlorophenyl- imino-1,3,6-
thiadiazepine (V), benzo-(4,5-d)-2, 7 -di-p-chlorophenylimino 1,3,6-
thiadiazepine (VI), benzo-( 4,5-d)-2, 7-di-t-butyl- imino-1,3,6-thiadiazepine
(Vll) in different percentages of acetone-water, ethanolwater
and dioxane-water mixtures have been measured. From the
data the relative viscosities have been calculated which are used to
measure the molecular interactions in the solutions and to study the
viscosity behaviour of substituted benzo-1,3,6-thiadiazepines on the
basis of the presence of different substituents.
