Tributylphosphane Uses

Tributylphosphine (CAS NO.998-40-3) is used as main ligand of homogeneous catalyst in the petrochemical. It is also used as reducing agent, olefin polymerization catalyst.

Tributylphosphane Production

Tributylphosphine (CAS NO.998-40-3) is prepared industrially by the reaction of phosphine with butene.
PH₃ + 3CH₂=CHCH₂CH₃ → P(CH₂CH₂CH₂CH₃)₃
It can be prepared in the laboratory by reaction of the appropriate Grignard reagent with phosphorus trichloride.
3BuMgCl + PCl₃ → PBu₃ + 3MgCl₂
