Preparation of fluorosilicon compounds
Methods of synthesizing fluorosilanes containing cyano-substituted alkyl groups are provided. For example, 3-cyanopropyldimethylfluorosilane may be produced by reacting tetramethyldisiloxane and boron trifluoride to obtain fluorodimethylsilane and then reacting the fluorodimethylsilane with allyl cyanide, in the presence of a hydrosilylation catalyst.
Reactive perpendicular aligned organosilicon material and manufacture method of liquid crystal display panel
A reactive perpendicular aligned organosilicon material is provided, having a general structural formula in the form of A-R, where A is SiCl.sub.3 and R represents a linear chained or a branched chained alkyl group with 5-20 carbon atoms. A CH.sub.2 group in the alkyl group is substituted by a phenyl group, a naphthenic base, CONH, COO, OCO, S, CO, or CHCH, or an F atom or a Cl atom substitutes an H atom in the alkyl group. A Cl atom in the reactive perpendicular aligned organosilicon material and OH on a surface of a substrate having no PI thereon form a hydrogen bond, leading to vertical arrangement of liquid crystal molecules between two opposite substrates.
Process for preparation of 3-methacryloxypropyldimethylchlorosilane in continuous flow reactor
A process for the preparation of 3-methacryloxypropyldimethylchlorosilane by reaction of allylmethacrylate with dimethylchlorosilane in the presence of a hydrosilylation catalyst, characterized in that the reaction is carried out in the absence of a peroxide is provided. The process includes providing a first stream containing allylmethacrylate. A a second stream containing dimethylchlorosilane is provided. The streams contact in a continuous flow reactor in the presence of the hydrosilylation catalyst, thereby producing 3-methacryloxypropyldimethylchlorosilane. A product stream is continuously removed from the continuous flow reactor.
METHOD FOR PRODUCING ORGANIC COMPOUND, AND DEVICE FOR PRODUCING ORGANIC COMPOUND
Provided is a method for producing an organic compound, said method including a step for repeating an operation in which a liquid containing an organic solvent is passed through a packed column packed with magnesium, a material containing an organic halide being added to the liquid before it is passed through. Further provided is a device for producing an organic compound, said device comprising: a packed column which is packed with magnesium; a liquid passing unit which repeats an operation in which a liquid containing an organic solvent is passed through the packed column; and a material adding unit which adds a material containing an organic halide to the liquid before it is passed through.
REACTIVE PERPENDICULAR ALIGNED ORGANOSILICON MATERIAL AND MANUFACTURE METHOD OF LIQUID CRYSTAL DISPLAY PANEL
A reactive perpendicular aligned organosilicon material is provided, having a general structural formula in the form of A-R, where A is SiCl.sub.3 and R represents a linear chained or a branched chained alkyl group with 5-20 carbon atoms. A CH.sub.2 group in the alkyl group is substituted by a phenyl group, a naphthenic base, CONH, COO, OCO, S, CO, or CHCH, or an F atom or a Cl atom substitutes an H atom in the alkyl group. A Cl atom in the reactive perpendicular aligned organosilicon material and OH on a surface of a substrate having no Pl thereon form a hydrogen bond, leading to vertical arrangement of liquid crystal molecules between two opposite substrates.
Reactive perpendicular aligned organosilicon material and manufacture method of liquid crystal display panel
The disclosure provides a reactive perpendicular aligned organosilicon material and a manufacture method of a liquid crystal display panel, a general structural formula of the reactive perpendicular aligned organosilicon material is A-R, A is SiCl.sub.3; R represents a linear chained or a branched chained alkyl group with 520 C atoms, a CH.sub.2 group in the alkyl group is substituted by a phenyl group, a naphthenic base, CONH, COO, OCO, S, CO or CHCH, or a F atom or a Cl atom substitutes for a H atom in the alkyl group. A Cl atom in the reactive perpendicular aligned organosilicon material and OH on a surface of the substrate without a PI film can form a hydrogen bond, leading to vertical arrangement of liquid crystal molecules.
PREPARATION OF FLUOROSILICON COMPOUNDS
Methods of synthesizing fluorosilanes containing cyano-substituted alkyl groups are provided. For example, 3-cyanopropyldimethylfluorosilane may be produced by reacting tetramethyldisiloxane and boron trifluoride to obtain fluorodimethylsilane and then reacting the fluorodimethylsilane with allyl cyanide, in the presence of a hydrosilylation catalyst.
Method for producing aryl-functional silanes
A method for preparing a reaction product including an aryl-functional silane includes sequential steps (1) and (2). Step (1) is contacting, under silicon deposition conditions, (A) an ingredient including (I) a halosilane such as silicon tetrahalide and optionally (II) hydrogen (H.sub.2); and (B) a metal combination comprising copper (Cu) and at least one other metal, where the at least one other metal is selected from the group consisting of gold (Au), cobalt (Co), chromium (Cr), iron (Fe), magnesium (Mg), manganese (Mn), nickel (Ni), palladium (Pd), and silver (Ag); thereby forming a silicon alloy catalyst comprising Si, Cu and the at least one other metal. Step (2) is contacting the silicon alloy catalyst and (C) a reactant including an aryl halide under silicon etching conditions.
