The PRF also recovers Am from the raffinate of the TBP-solvent extraction plutonium-purification process. The process employs 30 v/o dibutyl butylphosphonate in CCI4 as the solvent to extract both americium and residual plutonium from the high-nitrate feed solution, adjusted to about pH 1 by the addition of NaOH. Americium is selectively stripped from the solvent and purified by a cation-exchange procedure. [Pg.607]

To enantioresolve a tz-0,0 -dibenzylcalix[4]arenes, their (5)-MaNP acid esters were prepared and separated well by HPLC giving all four possible diastereomers. The AC of one of esters, (—)-131, was clearly determined by X-ray crystallography as shown by the use of (5)-MaNP acid moiety as an internal reference. From the results of X-ray and CD studies, the ACs of the remaining three derivatives were determined. In a similar manner, anti-O,O -dibutyl-p-ierf-butylthiacalix[4]arenes were enantioresolved as (5)-MaNP esters by HPLC, and the AC of derivative (—)-132 was determined as shown by X-ray crystallography based on the known AC of MaNP group. ... [Pg.1655]

Acetylsucrose [63648-81-7] has been prepared in 40% yield by direct acetylation of sucrose using acetic anhydride in pyridine at 40° C (36). The 6-ester has subsequently been obtained in greater than 90% yield, by way of 4,6-cycHc orthoacetate. Other selective methods for the 6-acylated derivatives include the use of alkyl tin reagents such as dibutyl tin oxide (37) and of dibutyl stannolane derivatives (38). Selective acetylation of sucrose by an enzymic process has also been described. Treatment of sucrose with isopropenyl acetate in pyridine in the presence of Lipase P Amano gave, after chromatography, 6-0-acetylsucrose (33%) and 4/6-di-O-acetylsucrose (8%). The latter compound has been obtained in 47% yield by the prolonged treatment (39). [Pg.33]

Natriumboranat/Kobalt(II)-chlorid (s.S. 115) reduziert aliphatische undaroma-tische Sulfoxide in Athanol mit guten Ausbeuten zu den entsprechenden Sulfanen. Mit dieser Methode erhalt man7 z.B. Dibutyl-sulfan (98% d.Th.), Diphenyl-sulfan (95% d. Th.) oder Thiuxanthen (100H/o d. Th.). Dibenzyl-sulfoxid und Tetrahydro-thiophen-1-oxid werden praktisch nicht angegriffen. [Pg.465]
