Effect of Modification on the Physicochemical and Thermal Properties of Organophilic Clay Modified with Octadecylamine

Organophilic clay was modified by ion exchange reactions using Octadecylamine. The reaction process was carried out at a temperature of 70oC for 90 minutes reaction time in a batch reactor equipped with a mechanical stirrer rotating at a speed of 300 rpm. Physicochemical and thermal properties of t...
