Abstract
Viscosity and conductance measurements were made in aqueous solution for the tetramethyl-, tetraethyl-, trimethylphenyl-, trimethylnaphthyl-, trimethylbenzyl-, triethylbenzyl-, and dimethyldibenzyl-ammonium chlorides which were the model compounds of basic dyes.
The viscosity B coefficients was calculated using the Jones-Dole equation. Judging from the positive B coefficients, trimethylphenyl-, trimethylbenzyl-, triethylbenzyl-, and dimethyldibenzyl-ammonium ions in aqueous solutions appear to be the structure makers.
The temperature coefficients of the Walden product suggests that the triethylbenzyl-ammonium ion appears to be a structure-maker, while for the trimethylbenzyl-, and trimethylphenyl-ammonium ions the structure-making and breaking effects appear to be cancelled.
It was found that there exists a relationship between the temperature coefficients of the Walden product and viscosity B coefficients.
