Van Gestel, Tim published the artcileSurface modification of γ-Al₂O₃/TiO₂ multilayer membranes for applications in non-polar organic solvents, Formula: C9H20Cl2Si, the publication is Journal of Membrane Science (2003), 224(1-2), 3-10, database is CAplus.

This paper reports the surface modification of hydrophilic γ-Al₂O₃/anatase-TiO₂ multilayer membranes by a silane coupling treatment, to obtain nanofiltration (NF) membranes applicable in non-polar solvents. Special care was given to optimization of the pore structure of the anatase top layer (microporous-mesoporous) and selection of the reaction medium (Et acetate) and silane coupling reagent ((CH₃)₂SiCl₂, C1 silane; C₈H₁₇CH₃SiCl₂, C8 silane). Hexane and water permeability were studied before and after silane treatment as an indication of the effect of the modification. No hexane permeability was obtained before modification. For microporous membranes fired at 300°C, the internal pore structure remained hydrophilic upon silane treatment, as evidenced by the fact that the hexane permeability remained zero. On the contrary, the more open membrane structure with mesopores obtained by firing at temperatures higher than 400°C, could be modified by a silane coupling reaction at the internal pore structure. The ratio of permeability, hexane/water, was altered from 0/1 for a firing at 300°C and a C1 silane treatment to 1/0 for a firing at 500°C and a C8 silane treatment. Standard PEG-retention measurements in water showed that the membranes fired at 400 and 450°C and modified with a C8 and C1 silane, resp., have pore sizes corresponding to those of nanofiltration (NF) membranes. These membranes were characterized by a mol. weight cut-off (MWCO) of 410 and a hexane permeability of 3 L.h^-1.m^-2.bar^-1 (400-C8) and a MWCO of 650 and a hexane permeability of 5 L.h^-1.m^-2.bar^-1 (450-C1).

Roumeliotis, P. published the artcileStructure and properties of n-alkyldimethylsilyl bonded silica reversed-phase packings, Name: Dichloro(methyl)(octyl)silane, the publication is Journal of Chromatography (1978), 211-24, database is CAplus.

The effects of the modifier functionality and the chain length of n-alkylchlorosilanes on the surface structure of packings and on their retention behavior in reversed-phase chromatog. were investigated. Comparative retention studies on 3 SiO₂ packings treated to maximum conversion with n-octyltrichlorosilane, n-octylmethyldichlorosilane, and n-octyldimethylmonochlorosilane (I) showed that the reversed-phase character is obtained by using I as the modifying reagent. A series of n-alkyldimethylsilyl bonded SiO₂ packings were prepared with differing n-alkyl chain lengths. Although the packings are hydrophobic, the maximum surface concentration is 2-4 μmol/m² and many hydroxyl groups (3-4 μmole/m²) can still be detected by isotopic exchange. The retention characteristics of hydrocarbons in MeOH-H₂O as the eluent were measured on these packings. The variation of the capacity factors of solutes was related to the total hydrocarbonaceous surface area of the bonded n-alkyldimethylsilyl group, the total hydrocarbonaceous surface area of the solute, and the mol. dipole moment of the solute. The studies are related to high performance liquid chromatog.

Ciganek, M. published the artcileModification of glass capillary inner surface for chromatography, Product Details of C9H20Cl2Si, the publication is Chemical Papers (1991), 45(1), 81-9, database is CAplus.

Conditions of glass capillary (50 μm inner diameter) inner surface modification by an aqueous solution of ammonia were studied. The resulting silica gel porous layer was modified chem. by methyloctyldichlorosilane. Under given etching conditions (temperature 250-300° for 16 h), a 5-10 volume% aqueous solution of ammonia was optimal. The static way of silylation by 10 volume% silane solution in toluene for 16 h at 250-280° with the column filled to 50-70% of its volume is optimal. This method provides a mech. stable porous layer 1-10 μm thick.

Three silicon-nickel complexes, Ni(bipy)(SiX3)2 (I,X3 = Cl3; II, X3 = MeCl2, bipy = 2,2′-bipyridyl) and Ni(h1-C5H5 )-(PPh3)(SiCl3) (III, C5H5 = cyclopentadienyl), were prepared by treatment of silicon hydrides with appropriate alkyl-nickel complexes, Ni(bipy)R2 (IV, R = Me, V, R = Et) and Ni(h1-C5H5)(PPh3)Et (VI), resp. Both complexes I and III reacted with HCl or DCl to give the corresponding chlorosilane HSiX3 (or DSiX3) and Ni(bipy)Cl2, in good yields. II reacted with tetracyanoethylene to afford MeCl2SiSiCl2Me, but in low yield. III reacted with MeI to form MeSiCl3 (23.5% yield). The silicon-nickel complex I was inactive as catalyst for hydrosilylation of olefins, whereas the alkyl complexes V and VI were active.

Matsuo, Y. published the artcilePreparation and characterization of silylated graphite oxide, Quality Control of 14799-93-0, the publication is Carbon (2005), 43(14), 2875-2882, database is CAplus.

Graphite oxide was silylated by various alkylchlorosilanes in the presence of butylamine and toluene, and new intercalation compounds were obtained. The silylating reagents with two or three Cl atoms at Si in them reacted with graphite oxide, while no reaction occurred when silylating reagents with only one Cl atom was used. The silylating reagent mainly reacted with hydroxyl group of graphite oxide, forming Si-O bonding. The role of butylamine was not only exfoliating graphite oxide layer but also scavenging HCl mol. which caused the decomposition of silylated graphite oxide. The Si content was almost constant �.6 mol/graphite oxide for the samples silylated by alkyltrichlorosilane with shorter alkyl chain lengths. It increased with the increase of alkyl chain length and reached 1.7 mol/graphite oxide. The higher Si content could be ascribed to further silylation on hydroxyl groups formed at Si atoms of silylating reagent bonded to graphite oxide, bridging two silylating reagents.

Anderson, Thomas F. published the artcileBis(2-thienyl)silanes: new, versatile precursors to arylsilanediols, Recommanded Product: Dichloro(methyl)(octyl)silane, the publication is Tetrahedron Letters (2006), 47(20), 3353-3355, database is CAplus.

Silanediols are effective bioisosteres for the hydrated carbonyl group. Current methods for the formation of silanediols place a number of constraints on how and where this functionality may be used. A range of arylsilanes that would allow both the formation of arylsilanediols and that are also compatible with multi-step synthetic routes, were studied as possible precursors to silanediols. Through this study bis(2-furyl)silanes and, in particular, bis(2-thienyl)silanes were identified as practical precursors to arylsilanediols.

Nonpolar chem. bonded stationary phases with branched or unbranched structure were synthesized, and their sp. surface areas, pore size distributions, and C contents were estimated Based on these data the number of silane mols. bonded to unit surface area of the original silica gel was calculated for each phase. Retentions of selected solute groups were measured in 4 mobile phases of various elution strength, prepared from MeOH-H₂O mixtures at various ratios. Dependence of k‘ on the length of the “bristle”, on the size and structure of the solute mol., and the elution strength of the mobile phase were plotted. Results are compared for pairs of phases having different structures but either the same total number of C atoms in the bonded mol. or the same length of the “bristle”. The synthesis of several halosilanes used for preparation of the bonded phases is described.

The preparation, using the fluidized bed technique, of a series of silica-based octylsilyl bonded phases with or without silica deactivation prior to silanization with mono-, di- or trifunctional chlorosilane is described. The surface structures of the bonded phases are determined by ²⁹Si and ¹³C cross-polarization and magic angle spinning NMR. Furthermore, the retention behavior of the phases is investigated with polar and nonpolar solutes, and data are correlated in terms of the bonding procedure and the functionality of the silanizing agent. Mass loading experiments for a single solute on selected packings give a maximum load of about 140.0 and 70.0 μg/g of packing for large and small particles, resp., irresp. of the silanizing agent.
