PRODUCTION OF 3-(N-(2-AMINOETHYL))AMINOPROPYLALKOXYSILANE

摘要

PURPOSE:To readily obtain the subject compound in good yield and high purity from high-boiling and readily available raw materials in one stage by reacting a hydroalkoxysilane with an N-allylethylenediamine in the presence of a platinum catalyst at a specified temperature. CONSTITUTION:A silane compound (e.g. triethoxysilane) expressed by the formula R HSi(OR<2>)3-a (R<1> and R<2> are 1-6C alkyl; a is 0-2) is reacted with an N- allylethylenediamine in the presence of a platinum catalyst (e.g. chloroplatinic acid) at a temperature of <110 deg.C, preferably 50-105 deg.C to afford the objective compound. Furthermore, the ratio of the silane compound to the N- allylethylenediamine is preferably (1.1:1)-(1:1.1). The concentration of the platinum catalyst is preferably 30-100ppm based on the total weight of the silane compound and the N-allylethylenediamine.
