Dreze and Duyckaerts investigated the extraction of Pu(IV) by di-n-butyl phosphoric acid (HDBP) from nitrate solutions as a function of nitric acid concentration, nitrate concentration, HDBP concentration, and ionic strength. Representative results are shown in Figs. 14 and 15. These experimenters were able to invoke the known stability constants of Pu(IV) nitrate complexes to fit the various functional dependencies. They consider the extraction reaction to be...

Tri-n-butyl phosphate and di-2-ethyIhexyl phosphoric acid (HDEHP) have been mainly used as extractants in several hydrometallurgical operations in the nuclear fuel cycle. Shukla and Mishra [27] have studied the extraction as well as transport behavior of uranium through BLM using 40% TBP in dodecane. The transport of by TBP at the feed-membrane...

Compounds which dissolve in concentrated sulphuric acid may be further subdivided into those which are soluble in syrupy phosphoric acid (A) and those which are insoluble in this solvent (B) in general, dissolution takes place without the production of appreciable heat or colour. Those in class A include alcohols, esters, aldehydes, methyl ketones and cyclic ketones provided that they contain less than nine carbon atoms. The solubility limit is somewhat lower than this for ethers thus n-propyl ether di olves in 85 per cent, phosphoric acid but n-butyl ether and anisole do not. Ethyl benzoate and ethyl malonate are insoluble.

After publishing what we considered the startling fact that a (AlkO)2-PO(OH), where Aik is 2-ethyl hexyl, is an extremely stable dimer in benzene, we discovered that KosolapofT and Powell had, nearly seven years earlier, shown (Alk)2PO(OH), where Aik is n-butyl or n-hexyl, to be dimeric in naphthalene. It is true that the existence of di-alkyl phosphinic acids as dimers doesn t prove that di-alkyl phosphoric acids are dimers, but it would certainly have provided a valuable hint.
