Abstract
The rheological behavior of alcohol-coal suspensions based on coals of different ranks prepared with the use of lower alcohols from the methanol-propanol series as a dispersion medium was studied. It was found that an increase in the length of an alkyl radical leads to an increase in the shear stress and viscosity of the alcohol-coal suspensions. In this case, the suspensions obtained with the use of isoalcohols are characterized by lower viscosity than the suspensions obtained with the use of normal alcohols. From the dependence of the shear stress and viscosity of alcohol-coal suspensions on the physical properties of lower alcohols, it follows that an increase in the dynamic viscosity and dipole moment, as well as a decrease in the dielectric constant (with increasing the length of the hydrocarbon radicals of alcohols), leads to an increase in the above rheological parameters.
