KATALYSATOR FOER OLEFIN-METATESREAKTION OCH FOERFARANDE FOER FRAMSTAELLNING AV DENNA.

摘要

A catalyst system for metathesis reactions of olefines, especially of propylene, which system comrpises a metal carbene complex on a solid carrier, in which the metal carbene complex has the formula: M(O)y(RCH2O)mXn9 wherein M is W or Mo; R is t-butyl; y is 0 or 1; and when y is o, m = 3 or 4, X is Br and n is from 5 to m; and when y is 1, m is from 1 to 4, X = Cl and n is from 4 to m.
