Title:
ACTIVITY SUSTAINING IMPROVED CATALYST SYSTEM FOR DOUBLE-DECOMPOSING OLEFIN
Document Type and Number:
Japanese Patent JPS63283756
Kind Code:
A
Abstract:
Improved catalytic systems of long active duration, comprising initially (a) a tungsten compound, (b) an organometallic compound and (c) a partially or totally fluorinated organic compound. Process of stabilization of these catalytic systems, comprising dissolving (a) in an organic solvent, contacting (b) with (a), agitation and heating at 0 DEG to 100 DEG C. for 0.5 to 60 minutes, then introduction of (c) into the mixture of (a) and (b). Use of these stabilised catalytic systems for the metathesis of olefins which carry functional groups or do not carry such groups.
