Octyltrimethoxysilane

Colorless transparent liquid

Liquid

General procedure: All catalysis reaction operations were performed in a 10 mL flat-bottomed tube without protection from air. The alkene (4.0 mmol) and the requisite amount of catalyst were placed in a dried tube and the reaction mixture was stirred for 5 min. Thereafter, the silane (4.4 mmol) was added and the resulting mixture was heated and stirred for the requisite time and then cooled to room temperature. The product phase was separated by decantation and the conversion of the alkene and the selectivity were determined by GC–MS analysis on an Agilent 26890N/59731 apparatus equipped with a DB-5 column (30 m × 2.5 mm × 0.25 μm). [Example 27] Hydrosilylation Reaction of 1-octene with Trimethoxysilane Using Cobalt Pivalate and IMes (0243) A screw-top vial was charged with 3 mg (0.01 mmol) of cobalt pivalate in Synthesis Example 3 as a catalyst, 6 mg (0.02 mmol) of IMes as a NHC ligand, 171 μl, (1.3 mmol) of trimethoxysilane as a hydrosilane, and 157 μl, (1.0 mmol) of 1-octene. The contents were stirred at 80° C. for 24 hours. After cooling, analysis was made by General procedure: The preparation of the alkali metal alkylsiliconates is carried out by the method in R. Murugavel et al., Solid State Sciences 2001, 3 (1-2), 169-182. As an alternative, the procedure in the examples in GB675188A can be employed. (0129) For example, nOctSi(ONa)3 is prepared by introducing 1 mol of nOctSi(OMe)3 from ABCR (97% pure) into a solution of 10 mol of NaOH in 400 g of water over a period of 30 minutes. The reaction is then completed under reflux within 4 hours. Distilling off the solvent gives a concentrated solution or complete drying gives the product as a solid.General procedure: All catalysis reaction operations were performed in a 10 mL flat-bottomed tube without protection from air.

Methanol-d4 and DMSO-d6 were used as solvents.[Example 27] Hydrosilylation Reaction of 1-octene with Trimethoxysilane Using Cobalt Pivalate and IMes (0243) A screw-top vial was charged with 3 mg (0.01 mmol) of cobalt pivalate in Synthesis Example 3 as a catalyst, 6 mg (0.02 mmol) of IMes as a NHC ligand, 171 mul, (1.3 mmol) of trimethoxysilane as a hydrosilane, and 157 mul, (1.0 mmol) of 1-octene. The contents were stirred at 80 C. for 24 hours. After cooling, analysis was made by 1H-NMR spectroscopy to determine the structure and yield of the product. As a result, it was confirmed that the signal assigned to the reactant disappeared completely. Instead, a multiplet at 0.65 ppm indicative of the signal assigned to proton on silicon-adjoining carbon in the desired product was observed, from which a yield was computed. The results are shown in Table 3With particular preference, the alkoxysilanes set out below are prepared by the process of the invention: ... isobutyltrimethoxysilane, isobutyltriethoxysilane, amyltrimethoxysilane, amyltriethoxysilane, claim 9 , wherein the organoalkoxysilane is selected from: phenyloctyldialkoxysilane, dodecylmethyldialkoxysilane, ... dodecylmethyldiethoxysilane, dodecyltriethoxysilane, hexadecyltrimethoxysilane, 1-docosenyltriethoxysilane, Alkoxysilanes suitable for the invention may include the following compounds: tetramethoxysilane (written TMOS), tetraethoxysilane (written TEOS), tetra-n-propoxysilane, methyltrimethoxysilane, methyltriethoxysilane, ethyltrimethoxysilane, ethyltriethoxysilane, propyltrimethoxysilane, propyltriethoxysilane, isobutyltrimethoxysilane, isobutyltriethoxysilane,

It is an additive and surface treatment agent for single-block dominant intermediate chain alkyl silane. It can be used as a surface treatment agent and can produce hydrophobes. It also has the characteristics of moisture resistance and corrosion resistance.
