Extraction of rare-earth elements(III) from nitric acid solutions with bis(diarylphosphorylmethyl)benzenes

Abstract Extraction of micro quantities of rare-earth elements(III) from HNO3 solutions as complexes with bis(diarylphosphorylmethyl)benzenes depending on the nature of organic diluent and HNO3 concentration in equilibrium aqueous ph

Synthesis method of trisubstituted phosphine oxide compound

The invention provides a synthesis method of a trisubstituted phosphine oxide compound. In the method, monohydric alcohol or dihydric alcohol which is inexpensive, readily available, stable and low intoxicity are used as alkylating agents, and cheap and readily available halosilane is used as a catalyst, thus directly obtaining the trisubstituted phosphine oxide compound through high-selectivityreaction. The reaction method is simple, the conditions are mild, no solvent is needed, the operation is easy, and water is a reaction by-product. The method has low requirements on the reaction conditions, and benzyl type, allyl type and aliphatic type alcohol can be used as the alkylating agent to realize the synthesis of the target phosphine oxide compound, and has a relatively wide applicationrange. The method can also conveniently scale up the production by 20 times and carry out the gram-level preparation of products, so the method should also have certain research and industrial application prospects.

Expedient synthesis of substituted (diphenylphosphinoylmethyl)benzenes

An efficient protocol for the synthesis of structurally diverse (diphenylphosphinoylmethyl)benzenes is described. The reaction employs readily available carboxylic acids, chlorodiphenylphosphine, and water as the reagents. A 97% reduction in the reaction

Tetraphenylalkylenediphosphine dioxides as extractants of palladium from nitric acid solutions

A complete series of tetraphenyl-α,ω-alkanediyldiphosphine dioxides Ph2P(O)(CH2)nP(O)Ph2 (n = 1-10) was synthesized, and their extraction properties were studied. 1,5-Bis(diphenylphosphinoyl)pentane showed the highest extraction ability with respect to palladium. A synergistic effect was observed in the extraction of palladium with toluene solutions of 1,5-bis(diphenylphosphinoyl)pentane in the presence of tributyl phosphate.
