Allgemeine Beschreibung

Potassium acetate is an osmotic agent that can be prepared by the reaction between acetic acid and potassium hydroxide. It has replaced urea and glycol for deicing process. Its potential as a substitute to calcium chloride for osmotic distillation has been investigated. It intercalates with the hydroxyl groups on the kaolinite surface leading to surface modification. It acts as a catalyst that accelerates the acetylation of wood at low temperature.

Anwendung

Potassium acetate has been used during granule bound starch synthase (GBSS) activity assay. It may be used as an activator to produce waste tea activated carbon (WTAC).

Potassium acetate is currently made by reacting petroleum-based acetic acid with potassium hydroxide. An alternate process, anaerobic fermentation of dextrose with Clostridium thermoaceticum, could be used and could possibly be cheaper. Growth characteristics and productivity of the fermentation were optimized
