Paragraph 0012; 0013; 0014, (2017/10/31)
The invention relates to an ester exchange method for preparing vinyl tri-(2- methoxy ethyoxyl)-silane, and belongs to the technical field of organic chemical. The ester exchange method uses ethylene glycol monomethyl ether and vinyl trimethoxy silane as raw materials, uses neutral double salt type catalyst to perform the ester exchange reaction, and generates tri-(2- methoxy ethyoxyl)-silane. Through filtering and recycling, the catalyst can be repeatedly used. Compared with traditional esterification method, the method has the advantages that 1, the ester exchange reaction process cannot cause the deepened color of product, methanol is removed by distilling after reaction, and the product can be obtained by direct filtering. 2. The catalyst can be recycled and repeatedly used for 10 times, and the activity is still kept.

PROBLEM TO BE SOLVED: alkylalkoxysilane compounds useful as a chemical product having various functions, and [...] or obtained from the same and to provide a manufacturing method thereof. SOLUTION: the alkylalkoxysilane, or a methoxy group and an ethoxy group, an alkyl group oxystyrene, thioalkyl group, on the same silicon atom or an alkyl group halogenopyridine structure having, for example, a plurality of silane-based or methoxysalicylic naphtholsulfonic, regular porous structure having a solid acid and alcohol in the presence of catalyst inorg. by reaction can be produced. Furthermore, water and the like of [...] alkylalkoxysilane obtained by reaction, is allowed to coexist with acid or the like can be performed efficiently.

, (2008/06/13)
A process for preparing an alkoxysilane with an acidic chloride content of less than 10 ppm by weight, comprising: reacting a chlorosilane with an alcohol in a water-free and solvent-free phase to form a product mixture containing alkoxysilane and residual acidic chloride, with removal of resultant hydrogen chloride from the product mixture, then adding liquid or gaseous ammonia, in an amount corresponding to a stoichiometric excess, based on the content of acidic chloride, to form an ammonia-containing product mixture, treating the ammonia-containing product mixture at a temperature between 10 and 50 DEG C., wherein the ammonia and acidic chloride undergo neutralization, to form a crude product, and optionally, then separating off a salt formed in the course of neutralization, from the crude product, and recovering the alkoxysilane by distilling the crude product.
