A closer look at the development and performance of organic–inorganic membranes using 2,4,6-tris[3(triethoxysilyl)-1-propoxyl]-1,3,5-triazine (TTESPT)

Abstract

2,4,6-Tris[3(triethoxysilyl)-1-propoxy]-1,3,5-triazine (TTESPT) is a new precursor for preparing membranes. The TTESPT-derived silica membrane exhibits a significant degree of selectivity for C₃H₆–C₃H₈ ∼37 at a permeation temperature of 50 °C, which greatly surpasses the upper-bounds of selectivity and permeance trade-off of carbon membranes. This indicates the potential for further development toward C₃H₆–C₃H₈ separation applications.
