| POTASSIUM SELENOCYANATE Usage And Synthesis |
| Chemical Properties | white to light beige crystalline powder or needles | | Uses | Potassium selenocyanate is used to prepare triphenylphosphine selenide by reacting with triphenylphosphine. It finds application in solid state NMR of heavy-metal nuclei which results in the preparation of several mercury thiocyanate and selenocyanate compounds. | | Uses | Increasing interest in solid state NMR of heavy-metal nuclei results in the preparation of several Hg-thiocyanate and selenocyanate compounds as potential models. Bowmaker, G.A. et al. Inorg. Chem. 1998, 37, 1734. | | Uses | Increasing interest in solid state NMR of heavy-metal nuclei results in the preparation of several Hg-thiocyanate and selenocyanate compounds as potential models. | | Safety Profile | Poison by
intraperitoneal route. When heated to
decomposition it emits very toxic fumes of
NOx, CN-, K2O, and Se. See also
SELENIUM COMPOUNDS and
CYANATES. | | Purification Methods | Dissolve it in acetone, filter and precipitate it by adding Et2O. |
