Procedimiento

Triisobutylene is reacted with phosphine according to Example 1 and the reaction mixture is subjected to vacuum stripping to remove unreacted triisobutylene and mono 2,4,4,6,6-pentamethylheptylphosphine. The residue is reacted with 1-dodecene according to Example 1 and a mixture is obtained of predominantly bis(2,4,4,6,6-pentamethylheptyl)-ndodecylphosphine and tris(2,4,4,6,6-pentamethylheptyl) phosphine. The above mixture is oxidized with hydrogen peroxide and the corresponding mixture of symmetrical branched and unsymmetrical branched tertiary phosphine oxides is obtained, useful as a metal extractant commposition.
