Abstract: A process for the continuous production of hydrophobic silica is disclosed. The process may include mixing hydrophilic silica with silicone in a mixer thereby forming a mixture. The process may also include heating the mixture in a reactor thereby forming a hydrophobic silica. The hydrophobic silica may be formed continuously by providing the hydrophilic silica and the silicone. A system for the continuous production of hydrophobic silica is also disclosed. The system may include a mixer for mixing the hydrophilic silica and silicone. The system may also include a reactor for heating the hydrophilic silica and the silicone comprising a channel having a plurality of heating zones, wherein the reactor is in fluid communication with the mixer. The system may also include a storage receptacle for storing the hydrophobic silica, wherein the storage receptacle is in fluid communication with the reactor.
