1. The phosphine and arsine absorb the ultraviolet light much more strongly than does silane, causing them to be deposited out on the walls of the container.

2. The catalytic systems containing the surface-active phosphine show a clear matching relation between the length of olefin chain and hydrophobic chain of the surface-active phosphine.

3. The conversion of phosphate into phosphine was an important biological reaction with potential value in application.

4. For most of tertiary phosphine ligands, the coupling yields of bromobenzene can reach to about 90%.

5. Importance of phosphine discovery for the phosphorus biogeochemistry circulation, eutrophication and the phosphorus elimination from domestic wastewater, is prospected.

6. Phosphine(PH3)is an important electronic specific gas which is mainly used in fields of N-type semiconductor doping, ion implement and chemical vapor deposition(CVD) etc.

7. The bidentate phenyl phosphine ligands which had good electron delocalization and chelation acted as a better ligand than monodentate phosphine ligand.

8. Especially, the ionic iridium complex of the phosphine oxazoline ligand obtains excellent reactional activity and enantioselectivity in the asymmetric hydrogenation of imine and olefin.

9. Tertiary phosphine ligands are sensitive to air and moisture. Thus we synthesized two stable ligands: the bidentate ON ligand and tridentate ONO ligand.

10. The novel supported bidentate phosphine palladium catalyst can be easily recovered by simple filtration and can be reused many times without loss of activity.

11. Bromopyridine substituted polystyrene resin and N-diphenyl phosphine pyrldi-ne substituted resin can be prepared by using chloromethylated polystyrene -dlv-inylbenzene.

12. For this, my library undertook 2007 phosphine gas sinks the test of ability in grain caboodle.

13. Phosphine (PH3) is a kind of extremely toxic, highly active, reductive gas, produced by the reduction of P biogeochemistry cycle, and has been proved to be trace gas existing stably in the atmosphere.

14. It is introduced that analyzing phosphine by GC method is a good method.

14. try its best to collect and make good sentences.

15. Phosphine is a toxic gas which ignites spontaneously in air.

16. Secondly, for the first time, a three-component olefination reaction between allylic carbonate, phosphine and aldehyde has been realized.

17. It also has evident sterilization effect on oilfield wastewater and is compatible with phosphine scaling inhibitor and quaternary-ammonium-salt biocide.

18. The features of isocyanate trimer and physical properties of tri - n - butyl - phosphine for isocyanate trimer catalyzer were introduced.

19. Docetaxel was prepared with a new type and high efficient catalyst, tributyl phosphine.

20. Thermodynamic considerations indicate that the reduction of phosphate to phosphine is endergonic.

21. However , shaking cultivation could promote the anaerobic phosphorus removal because of its helping phosphine release.
