Composites Based on Succinic Acid and Fumed Amorphous Silicas

It was found that composite systems with succinic acid, in which a significant part of the acid is in the voids between the particles of silica while the acid is in the form of nano- and microcrystalites, can be obtained from hydrophilic and hydrophobic silicas and their mixtures by the method of dosing mechanical loading. The textural characteristics of the composites depend on their composition, the mechanical load, and the humidity during their creation. Both hydrophilic and hydrophobic systems can be transferred to an aqueous medium and used in medicine and biotechnology.
