Potassium nitride

Potassium Nitride. K3N, mw 131.31, N 10.67%, gm-blk cryst, mp 343°. ignites spontaneously in air. Effervesces violently with w quantitatively evolving ammonia. Prepd by heating K amide to redness in a closed vessel or by striking an arc between a Pt cathode and a K anode under liq nitrogen (Refs 1—3)... [Pg.284]

Potassium loaded on a porous silicon nitride has been reported as a superbase catalyst. With appropriate pre-treatment, the catalyst was found to be highly active for 2,3-dimethylbut-l-ene isomerisation yielding 2,3-dimethylbut-2-ene in close to 100% selectivity. In order for high activity to be demonstrated, 30 wt% potassium amide was loaded by impregnation. A trace of Fc203 was also added on impregnation. A silicon nitride synthesised via a silicon diimide precursor which was pre-treated at 1000°C was found to be best and the catalyst was activated by heating in vacuo. The possibility that this resulted in active potassium nitride species via ... [Pg.108]
