What is the history of acetanilide toxicity?
In 1948, Julius Axelrod and Bernard Brodie discovered that acetanilide is much more toxic in these applications than other drugs, causing methemoglobinemia and ultimately doing damage to the liver and kidneys. As such, acetanilide has largely been replaced by less toxic drugs, in particular acetaminophen,...
How does acetanilide affect the environment?
Acetanilide may be released into the environment in various waste streams from its production and use as an intermediate in drug and dye production, as a stabilizer in hydrogen peroxide and cellulose esters, as a plasticizer, and as a rubber accelerator.
What is the difference between acetanilide and acetylarylamine?
Acetanilide is a white to gray solid. (NTP, 1992) N-Acetylarylamine is an odourless solid chemical of leaf or flake-like appearance. It is also known as acetanilide, N-phenylacetamide, acetanil, or acetanilid, and was formerly known by the trade name Antifebrin.
What is the difference between acetanilide and N-phenylacetamide?
ACETANILIDE is a white to gray solid. N-phenylacetamide is a member of the class of acetamides that is acetamide in which one of the hydrogens attached to the nitrogen is substituted by a phenyl group. It has a role as an analgesic. It is a member of acetamides and an anilide. It derives from an acetic acid.

How do I calculate theoretical yield?
To find the theoretical yield:Balance the reaction.Identify the limiting reagent, which is the reagent with the fewest moles.Divide the fewest number of reagent moles by the stoichiometry of the product.Multiply the result of Step 3 by the molecular weight of the desired product.
What is the theoretical yield of acetanilide when we used the 5.1 gm of aniline?
The theoretical yield of acetanilide is 4.35g.
How do you determine melting point?
The melting point of an organic solid can be determined by introducing a tiny amount into a small capillary tube, attaching this to the stem of a thermometer centred in a heating bath, heating the bath slowly, and observing the temperatures at which melting begins and is complete.
What is melting point?
Melting point is the temperature at which a given solid material changes from a solid state to a liquid, or melts.
What do you mean by melting point?
melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
What is used of acetanilide?
acetanilide, synthetic organic compound introduced in therapy in 1886 as a fever-reducing drug. Its effectiveness in relieving pain was discovered soon thereafter, and it was used as an alternative to aspirin for many years in treating such common complaints as headache, menstrual cramps, and rheumatism.
What is the functional group of acetanilide?
amide functional groupAcetanilide has an amide functional group, meaning it has a nitrogen atom bonded directly to a carbonyl (carbon-oxygen double bond).
What is the nature of acetanilide?
Acetanilide is a natural product found in Dendrobium moniliforme, Dendrobium officinale, and other organisms with data available. N-phenylacetamide is a member of the class of acetamides that is acetamide in which one of the hydrogens attached to the nitrogen is substituted by a phenyl group.

How do you find the theoretical yield of p Bromoacetanilide?
Procedure is as follows: Add 0.25g acetanilide to 10 mL glacial acetic acid. Add 1 mL of brominating solution (brominating solution is a mixture of 10.5 mL bromine and 100 mL glacial acetic acid). That's all there is in terms of reactants, besides using 20 mL ice cold water to transfer it.
Does recrystallization have theoretical yield?
1 Answer. Your recrystallized product is the actual yield. The theoretical yield will have been calculated beforehand using stoichiometry, or your teacher may have given it to you.
What is the limiting reagent in preparation of Acetanilide?
Here limiting reagent is aniline; hence yield should be calculated from its amount taken.
