Product Details

Tertiarybutylphosphine (TBP) CAS:2501-94-2 Melting point: 4℃ Boiling point: 54℃ Vapor pressure: lgp(Torr) = 7.552-1529/T(K) Storage temperature: Safe temperature ≤37 ° C Product grade: 99.9999% Tertbutylphosphine is an organic phosphine compound with the chemical formula C4H11P. It is a colorless to light yellow transparent liquid with the odor of garlic. This compound is prone to oxidation in air, and its preparation process needs to be carried out under anhydrous and oxygen free conditions. At present, the main preparation method is to use diethylene glycol dimethyl ether as a solvent and obtain tert butyl phosphine dichloride by reduction with lithium aluminum tetrahydrogen. The preparation reaction is usually carried out at 70 ℃, (0.1-0.08) Mpa, and the products are collected through vacuum distillation.
