General description

contains sodium stabilizing counterion

LUDOX® SM colloidal silica is used in the synthesis of propargylamines.

Application

LUDOX® SM colloidal silica has been used as a model solute to study the rejection behavior of carbon nanotube membranes. It was modified with bis (1(3-trimethoxysilylpropyl)-3-methyl-imidazolium) copper tetrachloride to be used as a catalyst for the preparation of propargylamines.
