Dibutyl-butylphosphonate

Tests by Mobil Oil Corporation [74] on dibutyl butylphosphonate showed that its toxic effects on rats were moderate at 3gkg (oral), and for rabbits it was nontoxic at >5gkg (dermal) exposure. With DEHPA, acute toxicity was found for rats at concentrations of 1.4 gkg (oral).

The PRF also recovers Am from the raffinate of the TBP-solvent extraction plutonium-purification process. The process employs 30 v/o dibutyl butylphosphonate in CCI4 as the solvent to extract both americium and residual plutonium from the high-nitrate feed solution, adjusted to about pH 1 by the addition of NaOH. Americium is selectively stripped from the solvent and purified by a cation-exchange procedure.

Dibutyl butylphosphonate (DBBP), (QH90)2(C4H9)P0, extracts Am(iii) from nitrate media more strongly than TBP and was used in a production process at Hanford [16].
