Recent developments in the heterogeneous catalysts for olefin cross-metathesis are summarized in this review.

A novel WO 3/Al 2O 3 Catalyst for metathesis of olefine were synthesized by the high power CO 2 laser under nonequilibruim condition.

Among them,attention was widely paid to the olefin metathesis reaction, due to its suitability to situation in China,lower cost and elasticoperation.

In the short term, the integration of refineries and petrochemical plants as well as the processes of olefin metathesis, C_4～C_8 olefin catalytic cracking can greatly boost the domestic production of o.

The mechanism of C_4-olefin metathesis to produce propylene and the Re-based catalysts for the metathesis were introduced.

Effects of acidity and pore structure of catalysts on the activity and product distribution in cumene disproportionation;

The Disproportionation of Hydroalkoxysilanes Catalyzed by KF;

Nano-Ni was first used as catalyst for disproportionation of resin acid.

Study on the disproportionation reaction kinetics of methyl phenyl carbonate;

Preparation of Cu/nano-SiC composite powder in disproportionation reaction and replacement reaction;

The plating baths based on reduction and disproportionation reactions have poor stability while the replacement-based bath is stable,and the deposit has uniform thickness.
