Potassium isoamyl xanthate

Potassium isoamyl xanthate [61792-26-5] M 202.4. Crystd twice from acetone-ethyl ether. Dried in a desiccator for two days and stored under refrigeration. 

Potassium isoamyl xanthate (potassium O-isoamyl dithiocarbonate) [61792-26-5] M 202.4, pK 1.82 (pK 2.8 free acid). Crystalhse it twice from acetone/diethyl ether. Dry it in a desiccator for two days and store it under refrigeration. Its solubility in Mc2CO is 2.3% at 56°.

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).
