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

摘要

The viscosities and densities of benzo-(4,5-d)-2,7-diphenyhl-imino-1,3,6-thiadiazepine (I), benzo-(4,5-d)-2,7-di-o-tolylimino-thiadiazeine (III), benzo-(4,5-d)-2,7-di-p-tolylimino-1,3,6-thiadiazepine (IV), benzo-(4,5d)-2,7-di-o-chlorophenyl-imino-1,3,6-thiadiazepine (V), benzo-(4,5-d)-2,7-di-p-chlorophenyhlimino-1,3,6-thiadiazepine (VI), benzo-(4,5-d)-2,7-di-t-butyl-imino-1,3,6-thiadiazepine (VII) in different percentages of acetone-water, ethanol-water 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 behviour of substituted benzo-1,3,6-thiadiazepines on the basis of the presence of different substituents.
