Process for preparation of aminopropylalkoxysilane.

摘要

A process for the preparation of an aminopropylalkoxysilane, which comprises reacting a hydrosilane compound with an allylamine compound in the presence of at least one member selected from the group consisting of phosphorus compounds having a phosphorus-nitrogen bond, which are represented by the following formulae: <CHEM> wherein Z<1>, Z<2>, Z<3>, Z<4>, Z<5> and Z<6> independently represent a hydrogen atom, an aliphatic hydrocarbon group having 1 to 8 carbon atoms, an alicyclic hydrocarbon group having 5 to 8 carbon atoms or an aromatic hydrocarbon group, and a rhodium compound. According to this process, the aminopropylalkoxy silane can be prepared in a high yield at a low cost and a high efficiency, while controlling the formation of the beta -compound to a very low level.
