The present invention provides a process for the production of hydrophobic inorganic oxide products which comprises reacting the inorganic oxide particles with organohalosilanes, preferably organochlorosilanes, to produce hydrophobic organosilane coated inorganic oxides. It is preferred that the organohalosilane compounds be reacted with the inorganic oxide particles in an aqueous slurry and subjected to intense mixing. The inorganic oxide pigments prepared by the processes of this invention have essentially quantitative retention of the organosilanes and contain no adsorbed aldehydes on their surface. The by-products produced in the preferred embodiments of the invention are innocuous salts, which are environmentally safe and readily disposable.

A invenção atual fornece um processo para a produção de produtos inorgánicos hydrophobic que compreende reagir as partículas inorgánicas do óxido com os organohalosilanes, preferivelmente organochlorosilanes do óxido, para produzir organosilane hydrophobic óxidos inorgánicos revestidos. Prefere-se que os compostos do organohalosilane estejam reagidos com as partículas inorgánicas do óxido em uma pasta aqueous e sujeitados a misturar intenso. Os pigments inorgánicos do óxido preparados pelos processos desta invenção têm essencialmente a retenção quantitative dos organosilanes e não contêm nenhum aldeído adsorbed em sua superfície. Os by-products produzidos nas incorporações preferidas da invenção são os sais innocuous, que são ambiental seguros e prontamente descartáveis.
