发明名称 Process for purifying low molecular weight hydridosilanes
摘要 The present invention relates to a process for purifying low molecular weight hydridosilane solutions, in which a solution to be purified comprising a) at least one low molecular weight hydridosilane, b) at least one solvent and c) at least one impurity selected from the group of the compounds having at least 20 silicon atoms and/or the group of the homogeneous catalyst systems is subjected to a crossflow membrane process with at least one membrane separation step using a permeation membrane.

主权项 1. A process for purifying a low molecular weight hydridosilane solution, comprising: subjecting a solution to be purified, comprising a. at least one low molecular weight hydridosilane, b. at least one solvent, and c. at least one impurity selected from the group consisting of a compound having at least 20 silicon atoms and a homogeneous catalyst system, to a crossflow membrane process with at least one membrane separation employing a permeation membrane.
