Patent

CA 2115775

Microporous materials of low acidity useful as sorbents and catalytic supports have been produced by pillaring tetrasilicic mica with silica polyoxocations generated by hydrolysis of organosilane precursors. Calcination at an intermediate temperature followed by washing of the solid with water is important in producing highly microporous material.

Divulgation de matières microporeuses de faible acidité, utiles comme sorbant et comme support catalytique, produites par dépilage de mica tétrasiliceux à l'aide de polyoxocations de silice générés par l'hydrolyse de précurseurs organosilaniques. La calcination à une température intermédiaire, suivie du lavage du solide avec de l'eau, est importante pour la production de matière hautement microporeuse.
