Title:
オレフィン系不飽和基質のオレフィン系二重結合を選択的に水素化する方法
Document Type and Number:
Japanese Patent JP4338806
Kind Code:
B2
Abstract:
A catalytic composition effective in the selective hydrogenation of olefinic double bonds, comprising the reaction product between: (A) at least one complex of a transition metal having the following general formula (I): M(R<1>)(R<2>)(R<3>)(R<4>) wherein: M is selected from titanium and zirconium, preferably titanium; each of the radicals R<1>, R<2>, R<3> or R<4>, independently, represents an organic or inorganic group of an anionic nature sigma -bound to M, on the condition that at least one, and preferablyat at least two, of these radicals is an organic group; and (B) at least one organometallic compound of magnesium having the following formula (II): Mg(R<5>)n(R<6>)(2-n) wherein: R<5> or R<6> each independently represent an aliphatic or aromatic hydrocarbon group having from 1 to 20 carbon atoms, and "n" is a decimal number between 0 and 2.0. Said catalytic composition advantageously and selectively promotes the direct hydrogenation of double bonds of an olefinic type, with high rates and with a reduced formation of isomers.
