Abstract
A process for producing surface modified metal oxide and/or organo-metal oxide compositions comprising esterifying at least a portion of the metal oxide and/or organo-metal oxide composition through contact with at least one esterification agent and at least one catalyst wherein the esterification agent and the catalyst are in the liquid phase. The process may be utilized to produce hydrophobic metal oxide and/or organo-metal oxide compositions at ambient temperature and/or ambient pressure conditions.
