Hydrogen Peroxide → 1-Propanol, 3,3'-[(1-methylpropyl)phosphinylidene]bis-

Participants

Reaction Steps

The residual product is believed to contain both s-butyl bis(3-hydroxypropyl) phosphine and 3-hydroxypropyl di-s-butyl phosphine. It is dissolved in an equal volume of isopropanol and oxidized with 30% hydrogen peroxide in an equal volume of isopropanol as described above in Example 1 until a negative carbon disulfide reading is obtained. The solution of oxidized phosphine is concentrated under reduced pressure to yield a syrupy yellow liquid weighing 555.6 g (99.2% yield on oxidation or a yield of 62.5% based on the starting butene).
