N-Butyl thiocyanate

Tri-n-butyl phosphate, ( -C4H9)3P04. This solvent is useful for the extraction of metal thiocyanate complexes, of nitrates from nitric acid solution (e.g. cerium, thallium, and uranium), of chloride complexes, and of acetic acid from aqueous solution. In the analysis of steel, iron(III) may be removed as the soluble iron(III) thiocyanate . The solvent is non-volatile, non-flammable, and rapid in its action.

Although many early studies on the solvent extraction of rare earth chloride into alcohols, ether, ketone, rare earth thiocyanates into butanol, rare earth nitrates into n-hexanol were done, extraction of rare earth nitrates by tri-n-butyl phosphate (TBP) proved to be the most promising system. The general step of extraction is ... 

Separations of various anions Using a solvent mixture composed of n-butyl alcohol, pyridine, and 1-5m ammonia solution in the proportions of 2 1 2, the following Rf values are obtained for the sodium or potassium salts chloride, 0-24 bromide, 0-36, iodide, 0-47 chlorate, 042, bromate, 0-25, iodate, 0-09 nitrite, 0-25 nitrate, 0-40 arsenite, 019 arsenate, 0 05 phosphate, 0-04 and thiocyanate, 0 56. The positions of the anions may be detected by spraying with ammoniacal silver nitrate potassium iodide and hydrochloric acid are particularly effective for chlorates, bromates, and iodates. The RF values provide the basis for the separation of a number of mixtures of anions, e.g. chloride and iodide, bromide or iodide and nitrate. 

The reaction of S-methylthiolanium fluorosulphate with thiocyanate ion gives mainly 4-(methylthio)butyl thiocyanate, result consistent with an hypothesis for the biogenesis of the latter the isothiocyanate has also been prepared (Scheme 225) N-Alkyl(aryl)-N-isothiocyanato-carboxamides were prepared by reacting the corresponding 2-chloroacetamides with potassium... 

Alkyl thiocyanates, R—S—C=N, of lower carbon numbers are highly toxic. These compounds liberate HCN as a result of metabolic processes and can cause death (Manahan 1989). Methyl thiocyanate [556-64-9] is highly toxic, with an intravenous LD50 value of 18 mg/kg in mice (NIOSH 1986). Ethyl thiocyanate [542-90-5], allyl thiocyanate [764-49-8], butyl thiocyanate [628-83-1], and amyl thiocyanate [32446-40-5] are all toxic compounds with an LD50 (subcutaneous) value of less than 100 mg/kg. The phenyl ester [5285-87-0] exhibits greater toxicity (intravenous LD50 value in mice 6.7 mg/kg) than that of the aliphatic esters of thiocyanic acid.

The modified titration curves of the fractionated (MA-St)n aqueous NaCl at various ionic strengths from 0.009 to 0.27 resembled the potentiometric behaviors of the maleic acid copolymer with n-butyl vinyl ether and poly(methacrylic acid) in aqueous salts. There was no precipitation or turbidity in the deionized polymer solution, except in aqueous NaCl of 0.27 M. The conformational transition from the compact to extended coil form was seen in diagp ams of the intrinsic viscosity vs. qp and the reduced viscosity in the range 0.1 < aj < 0.4 was independent of polymer concentration. Both the potentiometric and viscometric titration data showed that the pH-induced conformational transition of (MA-St)n in aqueous NaCl is due to intramolecular interaction. The unperturbed molecular dimensions were calculated from the viscosity data and the acid compact form of this copolymer was found to be not so compact as the conformations of globular proteins. Dilatometry did also indicate existence of the transition,and the transition was observed in aqueous solutions of various salts chlorides, bromides, perchlorates and thiocyanates of Na" ", K" ", Rb" ", Cs" " and...
