Formation of such self-adduct species, indicating Am(TTA) 3 HTTA, Ac(PMBP) 3 HPMBP and Ln(Ox) 3 (HOx) n (where n ¼ 1 or 2) has already been shown by Newman et al, [22] Chmutova et al, [23] Mathur et al, [24,25] and Hori et al [19] in the extraction of trivalent lanthanides or actinides by thenoyltrifluoroacetone (HTTA), phenyl-3-methyl-4-benzoyl-pyrazolone-5 (HPMBP) and 8-hydroxyquinoline (HOx). [17] Also given are the separation factors, defined as the difference in log(K ex b nHL ), for the Pr/Eu, Eu/Yb, and Pr/Yb pairs.…”

N-m-Trifluoromethylcinnamoyl-N-phenylhydroxylamine (CF 3 -CPHA) was synthesized. The acid-dissociation constant and distribution constant between chloroform and water of CF 3 -CPHA and N-cinnamoyl-N-phenylhydroxylamine (CPHA), which was the mother compound of CF 3 -CPHA, were determined spectrophotometrically. The extraction behavior of tervalent lanthanides (Ln), Pr, Eu, and Yb into chloroform solution containing CPHA or CF 3 -CPHA was studied. They are extracted as self-adduct chelates, LnL 3 (HL) 3 , where L and HL denote the ligand anion and neutral ligand, respectively. The extraction constants and separation factors for the lanthanides with CPHA and 599 CF 3 -CPHA were evaluated. The extraction constant with CPHA are smaller than that obtained with CF 3 -CPHA. However, it is observed that CPHA possesses higher selectivity than CF 3 -CPHA.

Vinylsulfonsaure und ihre Derivate kann man aus P-Chlorathansulfonsaurechloriden oder Carbylsulfaten herstellen. Mit dem Auffinden einer einfachen Syn fhese fur /'I-Chlorathansulfonsaurechlorid aus Chlorafhan oder A'than, Schwefeldioxyd und Chlor nach dem Reed-Verfahren gewann die Chemie der Vinylsulfonsaure technisches Interesse. Nicht minder wichtigund z. B. der niedrigen Preise der Komponenten Athylen und Schwefeltrioxyd wegen dem fl-Chlorathansulfonsaurechlorid iiberlegenist das Carbylsulfat. -Die Vinylsulfonsaureester liefern Additionsreaktionen rnit Alkoholen, Phenolen, Mercaptanen, Sulfinsauren, Carbonamiden, -imiden und -hydraziden, Aminen, Harnstoffen, Diazoniumsalzen und Nitroparaffinen. AuJerdem gehen sie Halogenierungs-, Nitrierungs-, Olefinierungsund Diels-Alder-Reaktionen ein. -Methoden zur Herstellung der freien Vinylsulfonsaure werden angegeben. Ihre Alkylester sind ausgezeichnete Alkylierungsniittel. Derivate der Vinylsulfonsaure werden beispielsweise als Weichmacher, Emulgatoren und Fungizide verwendet. I. Synthese von Vinylsulfonsaureestern A. Vinylsulfonsaure-alkylesterMan erhalt die Alkylester der Vinylsulfonsaure durch Reaktion von Alkoholaten rnit P-Chlorathansulfonsaurechlorid [2] nach Reaktion (a) [3]. RONa C1CH2-CH2-S02C1CH2=CH-SOa-OH. + 2 N a C l (a)Am einfachsten und rnit hohen Ausbeuten lauft die Reaktion mit 30-proz. methanolischer Natriummethylatlosung ab, die man bis zum Endpunkt zur p-Chlorathansulfonsaurechlorid-Losung zugibt. Uberschussige Base ist zu vermeiden, da es sonst zur Addition des Alkohols an die Doppelbindung kommt. Die hoheren Ester erhalt man analog. Die Vinylsulfonsaureester aliphatischer Alkohole hydrolysieren leicht in Vinylsulfonsaure und den entsprechenden Alkohol. Am leichtesten wird der Vinylsulfonsaure-methylester gespalten ; in Methanol als Losungsmittel erhalt man rnit Wasserdampf eine sehr reine Vinylsulfonsaureauch in technischem MaBstab [Reaktion (b)] [41.
