What is the purpose of adding sodium acetate to the reaction mixture in preparation of acetanilide?

∙ 12y ago
In the synthesis of acetanilide the hydrochloride salt of aniline is used in order to increase the solubility in water. The sodium acetate acts as a base and reacts with the HCl to produce acetic acid. Once the acetanilide product is no longer a hydrochloride salt, its solubility in water is decreased and it crystalises out. The main byproducts are sodium chloride and acetic acid which remain soluble in the water and are removed when the crude product is filtered off.

Why you use ice in the hydrolysis of ethyl acetate?
to freeze the reaction mixture, means to stop the further hydrolysis of ethyl acetate so that our readings couldn't interrupt.
You sodium acetate a element a compound or a mixture?
Sodium Ethanoate (Acetate) is a COMPOUND. It is the sodium salt of ethanoic(acetic) acid. It formula is CH3COO^-Na^+
Does sodium acetate form a homogeneous mixture in water?
white crystals are formed quickly when mixed and its an exothermic reaction meaning it gives off heat its what is used on hand warmers there is a video on youtube. the water is the acid and the sodium acetate is the base and takes a hydrogen from the water forming hydroxide ions and acetic acid. here is the reaction. C2H3O2-(aq) + H2O(l) HC2H3O2(aq) + OH-(aq)
Is sodium acetate flammable?
Yes, under the right conditions, sodium acetate is flammable. In fact, a mixture of sodium acetate and potassium nitrate, when intimately mixed, and heated, will explode -- sodium acetate is incompatible with strong oxidizers. The reaction is said to be about "one third as powerful" as that between potassium nitrate, potassium carbonate, and sulfur (in a 3:2:1 ratio -- "yellow powder") under the same conditions of slow heating. Do not try this at home (but, if you must, stick to quantities of a gram or less, and use hearing and eye protection, and keep away from anything flammable).
What happens when ethanol is mixed with vinegar?
Probably nothing since vinegar is a dilute concentration of acetic acid...However if you had pure acetic acid & ethanol the two would react to form an ester called ethyl acetate at room temperature: CH3CH2OH (ethanol) + CH3COOH (acetic acid) <==> CH3COOCH2CH3 (ethyl acetate) + H2O However since it is an equilibrium reaction you'd have a mixture of the products & reactants & would need to separate the mixture. Under the presence of an acid catalyst (such as sulfuric acid) & continuously removing the water you can increase the yield of ethyl acetate.

Is sodium acetate a mixture compound or element?
Sodium acetate is a chemical compound.
How can seprate p-nitro acetanilide mixture of para and ortho acetanilide?
The amide group on acetanilide is an ortho/para director, so a simple nitration should work: a mixture of sulfiric acid and nitric acid should be sufficient. Afterward, separation of the ortho and para compounds (by column chromatography, probably) would be necessary.
Is energy absorbed during preparation of a mixture?
Depends on the mixture. There are two different reactions when atoms bond: exothermic and endothermic. During an exothermic reaction, energy is given off in the form of heat or light. In a endothermic reaction, energy is absorbed.
Why is a large excess of acetic acid used in the preparation of isopentyl acetate?
Esterification of an acetic acid with isopentyl alcohol can can be used to prepare isopentyl acetate because the equilibria would not favor the formation of the ester, so equilibira will shift to the right IF we use excess amount of one of the reagents (acetic acid). We used large amounts of acetic acid because it's less expensive and it's easier to remove from a reaction mixture than isopropyl alcohol.
Is sodium acetate solution a metal?
No. Sodium acetate solution is a homogeneous mixture, which is a solution. Sodium acetate is an ionic compound formed from sodium ions and acetate ions. Sodium in sodium acetate no longer has the properties of sodium metal.
Can homemade sodium acetate make hot ice?
Yes. You can boil a mixture of sodium acetate in water and subsequently cool it. If you cause it to precipitate, it will feel hot.
You sodium acetate a element a compound or a mixture?
Sodium Ethanoate (Acetate) is a COMPOUND. It is the sodium salt of ethanoic(acetic) acid. It formula is CH3COO^-Na^+
What are some examples of a buffer?
Some examples of a buffer are mixture of ammonium hydroxide with ammonium chloride & mixture of acetic acid and sodium acetate.
