Anwendungen

Potassium phosphate is used as a fertilizer and food additive. It serves as a buffering agent to regulate pH. It is also used in optical modulators and for non-linear optics such as second-harmonic generation (SHG). It is involved in the phase-transfer catalyzed preparation of acetylenes from the corresponding vicinal dibromo compounds through double dehydrobromination. It is also useful for the oxidative coupling of thiols to disulfide.

Bemerkungen

Hygroscopic. Incompatible with strong oxidizing agents.
