Ethanol uranium complex

For example, in 1963 the photochemistry of magnesium phthalocyanine with coordinated uranium cations was studied in pyridine and ethanol and indicated the occurrence of PET to the uranium complex . A rapid photoinduced electron transfer (2-20 ps) followed by an ultrafast charge recombination was shown for various zinc and magnesium porphyrins linked to a platinum terpyridine acetylide complex . The results indicated the electronic interactions between the porphyrin subunit and the platinum complex, and underscored the potential of the linking para-phenylene bisacetylene bridge to mediate a rapid electron transfer over a long donor-acceptor distance. [Pg.198]

Alternative routes to homoleptic alkoxide complexes have been described, including electrochemical generation of U(OCH2CH3)4 from uranium metal in ethanol, alcoholysis (ROH R = Et, Pr , Bu ) of U( 7-C3H5)4 at -30 and generation of U[OCH(Bu )2]4 via... [Pg.222]

At pH 6.5-S.5 the enol form of dibenzoylmethane (formula 54.1), a reagent of the P-diketone group, forms a yellow uranyl chelate complex which has been used for determination of uranium [76,77]. It dissolves in aqueous ethanol medium containing pyridine, or may be extracted with ethyl acetate, butyl acetate, or CHCI3 [78]. [Pg.449]

ABSOLUTE ALCOHOL or ABSOLUTE ETHANOL (64-17-5) Forms explosive mixture with air (flash point 55°F/13°C). Reacts, possibly violently, with strong oxidizers, bases, acetic anhydride, acetyl bromide, acetyl chloride, aliphatic amines, bromine pentafluoride, calcium oxide, cesium oxide, chloryl perchlorate, disulfuryl difluoride, ethylene glycol methyl ether. Iodine heptafluoride, isocyanates, nitrosyl perchlorate, perchlorates, platinum, potassium- er -butoxide, potassium, potassium oxide, potassium peroxide, phosphonis(III) oxide, silver nitrate, silver oxide, sulfuric acid, oleum, sodium, sodium hydrazide, sodium peroxide, sulfmyl cyanamide, tetrachlorosilane, i-triazine-2,4,6-triol, triethoxydialuminum tribromide, triethylaluminum, uranium fluoride, xenon tetrafluoride. Mixture with mercury nitrate(II) forms explosive mercury fulminate. Forms explosive complexes with perchlorates, magnesium perchlorate (forms ethyl perchlorate), silver perchlorate. Flow or agitation of substance may generate electrostatic charges due to low conductivity. [Pg.1]

Besides fhe earfh alkali mefals mentioned, a positive reaction in the first step of analysis will be given by cadmium, cobalt, copper, manganese, nickel, zinc, and uranium(VI). But of fhese only the uranium(VI) can be extracted into chloroform in fhe second step of the analysis. The extraction is possible since the two water molecules in the calcium complex can by replaced by two ethanol molecules. This complex is soluble in chloroform. [Pg.40]
