What is Dibutyl butanephosphonate?
The Uses of Dibutyl butanephosphonate
Dibutyl Butylphosphonate is a reagent used in organic synthesis. It is used for uranium extractions as well as in the plasticizing industry.
Safety Profile
Poison by intraperitoneal and intravenous routes. Combustible when exposed to heat or flame. It can react vigorously with oxidizing materials. To fight fire, use foam, CO2, or dry chemical. When heated to decomposition it emits toxic fumes of POx.
Purification Methods
Purify by three recrystallisations of its compound with uranyl nitrate, from hexane. For method, see tributyl phosphate.
