chemical compound composition NH4C2H3O2 known in wider circles as ammonium acetate.In appearance it is a crystalline substance transparent or white.The product is used for its production of acetic acid.Extracted ammonium acetate by reacting the acid with ammonia.As materials are readily available and relatively cheap, this compound is used as a food additive (E264) or a preservative.Among the physical properties
stands hygroscopic.It has its ammonium acetate.Preparation of this material in the laboratory is possible in several ways.The reaction can be carried out with concentrated (glacial) acetic acid and ammonium carbonate (ammonium carbonate).The result of the reaction is ammonium acetate, and carbonic acid is unstable, it is converted in a short time to carbon dioxide and water.Next
reaction involves surging 80% acetic acid to a 10% surge of ammonia (ammonia).To the reaction requires low temperature.Dip into a container with ice flask with reagents, periodically shaking it vigorously.By evaporation of the filtrate, ammonium acetate.For
third reaction using nitrile acetic acid or acetonitrile.It is heated with water.Among the methods of preparation have found industrial application response when ammonium acetate was prepared from acetic acid by reaction with aqueous ammonia solution.
Among the methods of production of ammonium acetate can be isolated reaction wherein the compound is a byproduct of the processing timber chemically - ammonia.But the main purpose of this reaction - diacylation cellulose.
notable feature of ammonium acetate is its ability to decompose at a temperature of 112 ° C in acetamide and water.This reaction is often cited as an example of the salt decomposition at relatively low temperatures.
ammonium acetate is used in industry and in laboratory conditions as component fluids for anti-icing.The food industry has found in him an effective preservative.It is also used as a reagent during some kinds of organic synthesis.Laboratory and research considering the consumption of ammonium acetate as a component of buffer solutions and precipitation of proteins.
Technologies of printing on fabric or paint using ammonium acetate.It is used in the production of antibiotics and other products of the pharmaceutical industry.Also, it is widely used in the production of foam rubber, plastic, vinyl.
use of ammonium acetate for industrial purposes requires transportation and storage in large volumes.Typically, the crystalline powder is packed in bags or special woven paper boxes.For dry storage of used space, where the substance is in a sealed condition in their original packaging.The substance is not toxic and does not present a hazard to the health of staff.Precautions when handling this compound suggest protecting the skin and eyes.
If substance to a mucosal surface of the first via a copious flushing with clean water.After working with acetate ammmoniem should be thoroughly washed with soap and water.
in fire against the present compound is not dangerous.It is not explosive and is not easily ignited.Domestic chemical industry has adjusted release of substances in sufficient quantities to meet the needs of production.In addition, supplies of ammonium acetate from abroad.Traditionally, the main importer and here is China.
