1) Potassium acetate, crystalline powder, USP is, as its name suggests, the potassium salt of acetic acid and is used as a catalyst for producing polyurethanes2) In the food industry it is used as a food additive, an acidity regulator and a preservative
Potassium acetate is the potassium salt of acetic acid. It is manufactured through the reaction between a potassium base such as potassium hydroxide or potassium carbonate with acetic acid. It is an important macromineral with many physiological functions and is required for nerve conduction, cardiac, skeletal and smooth muscle contraction, energy generation, nucleic acid synthesis as well as mainlining the blood pressure and normal renal function. It can be taken as a nutritional supplement with antihypertensive effects and prevention effects against hypokalemia. It has several other common applications: (1) as a deicer; (2) as a food additive; (3) molecular biology applications such as DNA purification, tissue preservation, fixation and mummification; (4) Death penalty (5) as the catalyst during the production of polyurethanes.
ChEBI: A potassium salt comprising equal numbers of potassium and acetate ions
Potassium acetate, KC2H302, is a white, deliquescent solid, soluble in water and alcohol, insoluble in ether, that melts at 292°C. It is used as an analytical reagent, dehydrating agent, in medicine, and in crystal glass manufacture.
Potassium acetate is used in the manufacture of glass; as a softening agent for papers and textiles; as a dehydrating agent; and as a buffer. In medicine it is used as an expectorant and diuretic.
Potassium acetate is prepared by addition of potassium carbonate in a small volume of water to acetic acid solution, followed by evaporation and crystallization:
K2CO3+ 2CH3COOH →2CH3COOK + H2O
Used as buffers.
