gel-like suspension that was cooled to room temperature, filtered and washed withcopious amounts of de-ionised water to obtain a translucent gel-like substance thatturned white and solidified on drying in air. The white solid was then calcined at550 o C for 5 h giving a hard white, chalk-like solid that was readily ground.MCM-41-GPS, 81Synthesis of this material was by a method analogous to the method used for 33but using 93 (1.6 g) and 3-(glycidoxypropyl)trimethoxysilane, 32 (1.5 g, 6.4 mmol).Microanalysis gave 12.23% C and 2.17% H corresponding to a loading of 1.7 mmolg -1 of material.MCM-41-GPS-Trac, 88This material was synthesised by a method analogous to that used for thesynthesis of receptor material 43 but using 81 (1.2 g, 1.7 mmol g -1 ) and 46 (3.17 g,5.1 mmol). Microanalysis gave 18.05% C, 2.74% H and 1.60% N corresponding to aloading of 0.22 mmol g -1 of material.151
