TRIETHOXYSILYLPROPYL

The silane coupling agents which are frequently used are bis-(3-triethoxysilylpropyl)tetrasulphane and 3-thio-cyanatopropyl triethoxy silane. 

Addition of bis-(3-triethoxysilylpropyl)-tetrasulphide plus accelerator and sulphur can counter loss of crosslinking. Accelerator systems which respond to this antireversion agent are the thiazoles and the sulphenamides. Thiurams do not respond. For cure state equilibrium to be maintained the proportions of the three constituents (sulphur, accelerator and antireversion agent) are adjusted to give a constant modulus. 

In 2002 Mehnert and co-workers were the first to apply SILP-catalysis to Rh-catalysed hydroformylation [74], They described in detail the preparation of a surface modified silica gel with a covalently anchored ionic liquid fragment (Scheme 7.7). The complex N-3-(3-triethoxysilylpropyl)-4,5-dihydroimidazole was reacted with 1-chlorobutane to give the complex l-butyl-3-(3-triethoxysilylpropyl)- 4,5-dihydroimidazolium chloride. The latter was further treated with either sodium tetrafluoroborate or sodium hexafluorophosphate in acetonitrile to introduce the desired anion. In the immobilisation step, pre-treated silica gel was refluxed with a chloroform solution of the functionalised ionic liquid to undergo a condensation reaction giving the modified support material. Treatment of the obtained monolayer of ionic liquid with additional ionic liquid resulted in a multiple layer of free ionic liquid on the support. 

Conventionally, solutions of acrylamide or other acrylic monomers, or mixtures of them, can be photopolymerized onto flat glass surfaces which have previously been derivatized with acrylic groups to promote covalent and robust binding of the gel (e.g. by reaction with 3-(triethoxysilylpropyl)acryla-mide) [59]. Irradiation of the substrate occurs through a mask, so that poly-... 

The effectiveness of the coating has been investigated by separating phenolic compounds in the nonaqueous media. The EOF was found to be anodic and dependent on the pH of the separation buffer. In anofher study [66], imidazole containing zwitterionic salt (N-3-(-triethoxysilylpropyl)-4,5-dihy-droimidazole) was attached to the silica capillary wall via the formation of a covalent bond (Figure 6.8). 

Cleaned silicon wafers were silylated with A/-(3-triethoxysilylpropyl)-12-nitro-dodecanamide in toluene (20 ml of a 2% solution) at room temperature under nitrogen overnight. The wafers were thoroughly washed with chloroform, methanol, and acetone in that order, and suspended in glacial acetic acid (5 ml). Zinc dust (200 mg) was added in small portions and the mixture set aside for 5 h. The wafers were recovered and washed several times with distilled water, sodium carbonate solution (1% aq.), and again with distilled water. After rinsing with acetone, the wafers were stored under nitrogen. 

Jaroniec and coworkers were able to incorporate (up to 30mol%) tris[3-(trimethoxysilyl)-propyl]isocyanurate (ICS) (18) into mesoporous silica phases by co-condensation with TEOS.179,180 They also tested multifunctional hybrid materials based on ICS as potential Hg2+ adsorbents by direct co-condensation of ternary mixtures comprising TEOS (70 to 88 mol%), ICS, and another organosilane, namely bis[3-(triethoxysilyl)propyl]tetrasulfide, A-(3-triethoxysilylpropyl)-4,5-dihydroimi-dazole, or ureidopropyltrimethoxysilane.181 Ternary systems comprising TEOS, ICS, and MPTES, which showed a high adsorption capacity for Hg2+, were also reported (for PMOs based on ICS, see Section 3.4.3).182...

For the preparation of such a modified silica gel, the complex N-3-(3-triethoxy-silylpropyl)-4,5-dihydroimidazole 1 is reacted with 1-chlorobutane to give the complex Tbutyl-3-(3-triethoxysilylpropyl)-4,5-dihydroimidazolium chloride 2.
