Potassium isopropyl xanthate

When exposed to ait, the sodium salts tend to take up moisture and form dihydrates. The alkah metal xanthates are soluble ia water, alcohols, the lower ketones, pyridine, and acetonitrile. They are not particularly soluble ia nonpolar solvents, eg, ether or ligroin. The solubiUties of a number of these salts are Hsted ia Table 4. Potassium isopropyl xanthate is soluble ia acetone to ca 6 wt %, whereas the corresponding methyl, ethyl, / -propyl, n-huty isobutyl, isoamyl, and benzyl [2720-79-8] xanthates are soluble to more than 10 wt % (12). The solubiUties of the commercially available xanthates ia water are plotted versus temperature ia Figure 1 (14).

N aqueous solution of HCl, H2SO4 or H( I04, from which more than 99 % of technetium could be extracted into carbon tetrachloride at 20 C. The concentration of potassium xanthate was 0.1 M. Perrhenate remained entirely in the aqueous phase, thus separation from technetium could be readily achieved. Instead of carbon tetrachloride. other extractants like chloroform. 1,1,1-trichlorocthane, xylene or isopropyl ether are also suitable [153[.
