Abstract

Studies were carried out on the modification of silica with 3‐aminopropyltriethoxysilane in various solvents. The modified silica obtained was subjected to comprehensive evaluations of physicochemical properties, including the bulk density and the capacities to absorb water, dibutyl phthalate and paraffin oil. Particle size, particle size distribution, uniformity of the particles, tendency to form agglomerates, as well as particle surface morphology, were also examined using SEM and dynamic light scattering (DLS) techniques. The properties of the modified silica obtained were compared to evaluate the effects of the solvents used during the surface modification of the silica.
