Hydroformylierungsverfahren und darin verwendete Bisphosphitverbindung

摘要

A hydroformylation process for preparing a hydroformylated product by reacting an olefinic compound with hydrogen and carbon monoxide in the presence of a Group VIII metal catalyst, in the reaction of which there is present a phosphite compound having the formula (I), A<1> &lsqbstr& O-P(OR<1>)(OR<2>)]n (I> wherein R<1> and R<2> are respectively an aromatic hydrocarbon group which may be the same or different and the aromatic hydrocarbon group has at least a hydrocarbon group on a carbon atom adjacent to a carbon atom bonded with an oxygen atom as a substituent; A<1> is an n-valent organic group having an aliphatic hydrocarbon group, a cycloaliphatic hydrocarbon group or an aromatic hydrocarbon group bonded with an adjacent oxygen atom, which may respectively have a substituent; n is an integer of from 2 to 4; and the respective &lsqbstr& O-P(OR<1>)(OR<2>)] group may be the same or different. v
