What Is an Acetate?
Acetate is easily soluble in water. Sodium acetate and ammonium acetate can be used as meat preservatives and the like. Potassium acetate can be used as a diuretic, softener, and the like. Lead acetate can be used to make chrome yellow pigments. Zinc acetate can be used as a wood preservative and the like.
- English name: acetate; Russian name: .
- The chemical formula of acetate ion is [C2H3O2], it is a carboxylate ion, and
- Acetic acid, also known as acetic acid (36%-38%), glacial acetic acid (98%), the chemical formula CH3COOH, is a
- Sodium acetate is generally present as sodium acetate trihydrate with three crystal waters. Sodium acetate trihydrate is colorless and transparent or white crystals, which can be weathered and combustible in the air. Soluble in water, slightly soluble in ethanol, insoluble
- Potassium acetate is a chemical, white powder, used as an analytical reagent to adjust the pH value. Can also be used as a desiccant, manufacturing transparent glass, pharmaceutical industry. Can also be used as buffering agents, diuretics, fabric and paper softeners, catalysts and so on.
Acetate physicochemical properties

- Relative density: 1.57g / cm ^ 3 (solid) 25 ° C (lit.)
- Soluble in water, soluble in methanol, ethanol and liquid ammonia. Insoluble in ether and acetone.
- The solution is alkaline to litmus and not alkaline to phenolphthalein. Low toxicity. Flammable.
- Refractive index: n20 / D 1.370
- Water solubility: 2694 g / L (25 & ordm; C)
- Conditions to avoid during storage are: moisture, heat, fire, spontaneous combustion and strong oxidants.
Acetate use
- It can also be used as an anti-icing substance, replacing chlorides such as calcium chloride and magnesium chloride. It is less erosive and corrosive to soil, and is especially suitable for de-icing airport runways, but it is more expensive. Food additives (preservatives and control of acidity). Components of a fire extinguisher. Used in ethanol to precipitate DNA. It is used to preserve and fix biological tissues. It can be used in combination with formaldehyde. Potassium acetate can be prepared from the neutralization reaction between potassium hydroxide or potassium carbonate and acetic acid:
- 2CH 3 COOH + K 2 CO 3 2CH 3 COOK + CO 2 + H 2 O.
