Water-soluble rhodium(I)- and ruthenium(II)tertiary phosphine complexes with meta-mono-sulphonated triphenylphosphine (TPPMS) and 1,3,5-triaza-7-phosphaadamantane (PTA) as ligands catalyze the hydrogenation of aqueous HCO3- to HCO2- under mild conditions. ...
Chloro- and hydrido-complexes of ruthenium(II) with potassium (4-diphenylphosphino)benzenesulfonate (pTPPMS) were prepared and their properties were compared with those of the related complexes of (3-diphenylphosphino)benzenesulfonates. An X-ray crystal st ...
Treatment of Cl2CF2 with a base in the presence of an olefin gave chlorofluorocyclopropanes (I), which were distd. in a spinning band column and taken up in tetrahydrofuran (THF). This soln. was added dropwise to a stoichiometric amt. of Na in liquid NH3 a ...
The reactivity of hypoiodous acid (HOI) is an important factor for the fate of iodine in oxidative drinking water treatment. The possible reactions of HOI are its disproportionation, its oxidation to iodate (IO3-), or the reaction with natural organic matt ...
Aq. solns. of formic acid were exptl. investigated in a modified sweeping gas membrane distn. (SGMD) configuration. A thermostated sweeping gas was used in order to enhance the mass transfer performance. A new tubular module was designed and built for this ...
The electro-oxidn. of 1,4-benzoquinone in water soln. was investigated. The benzoquinone concn., intermediate products, dissolved org. C (DOC), COD, and toxicity of the oxidized soln. was monitored during oxidn. with Ti/IrO2 and Ti/SnO2 anodes (in the foll ...
The anodic behavior of Ni in HF-HCl aq. solns. was examd. The current efficiency for Ni dissoln. was detd. from the wt. loss of Ni polarized anodically, assuming that Ni dissolves as Ni2+. The dissoln. rate decreases markedly for a HF concn. of .apprx.50%. ...
The water-soluble tertiary phosphine complex of ruthenium(II), [RuCl2(PTA)(4)], (PTA. 1,3,5-triaza-7-phosphaadamantane) was used as catalyst precursor for hydrogenation of CO2 and bicarbonate in aqueous solution, in the absence of amine or other additives, ...
A general description of the electrolytic cond. behavior of highly charged strong polyelectrolytes in dil. and semidilute aq. solns. is presented. For the first time this model considers the effects of the molar mass, charge d. (for charge distances less t ...
Suspended org. and inorg. solids are removed from aq. soln. by adding an improved water-sol. acryloguanamine copolymer flocculant with mol. wt. >2000 and contg. 0-1000 units each of acrylamide, vinyl guanamine, acrylic acid, trimerized acrylonitrile struct ...
