	ACETANILIDE (N-PHENYLACETAMIDE)
		Acetanilide is an odourless, white flake solid or crystalline powder (pure form); soluble in hot water alcohol, ether, chloroform, acetone, glycerol, and benzene;; melting point 114 C and boiling point 304 C; can undergo self-ignite at 545 C, but is otherwise stable under most conditions.
		Acetanilide is used as an inhibitor of peroxides and stabilizer for cellulose ester varnishes.
		But acetanilide is not used directly for this application due to causing methemoglobinemia (the presence of excessive methemoglobin which does not function reversibly as an oxygen carrier in the blood).

	Acetanilide - Wikipedia, the free encyclopedia
		Acetanilide is used as an inhibitor in hydrogen peroxide and is used to stabilize cellulose ester varnishes.
		Acetanilide was used as a precursor in penicillin synthesis and other pharmaceuticals and its intermediates.
		Acetanilide has analgesic and fever-reducing properties; it is in the same class of drugs as acetaminophen (paracetamol).

	Olympus Microscopy Resource Center: Mortimer Abramowitz Gallery of Photomicrography - Acetanilide Crystallites
		Acetanilide is a synthetic compound that was first used for its fever reduction and painkilling properties in the late Nineteenth Century.
		This manufactured substance quickly replaced acetanilide in pharmacies because it is not as prone to generate blood disorders, and it continues to be widely used today.
		However, acetanilide may also be used in herbicides, nail polishes, and in the production of varnishes.

	EPA: Pesticides - Immunoassay Methods of Acetochlor Detection
		The acetanilide immunoassay of Millipore is not spectific and does not differentiate among alachlor, acetochlor, metolachlor and dimethenamid but rather detects their presence in varying degrees.
		In summary, the EnviroGard Acetanilide Plate Kit and the EHL automated acetanilide assays have sufficient accuracy and precision to serve as a screen for acetochlor in water at 1.0 ppb.
		The acetanilide immunoassay of Millipore is not specific and does not differentiate among alachlor, acetochlor, metolachlor and dimethenamid but rather detects their presence to varying degrees.

		This crude acetanilide is contaminated with acetic acid and aniline acetate.
		Acetanilide is quite soluble in boiling water, but not in cold water.
		Add another 25 mL of water to the crude acetanilide in your beaker and heat it on a hot plate or over a spirit lamp until the water comes to a boil.

		To improve the yield, dissolve any acetanilide remaining in the flask in hot water and again decant.
		As a test for acetanilide mix a small amount of acetanilide with an equal amount of sodium nitrite and sprinkle the mixture onto the surface of concentrated sulfuric acid.

		H, chlorosulfonic acid and the molar masses of acetanilide, sulfanilamide, etc. to determine the theoretical yield of the product starting from 1.0 g of acetanilide.
		To permit addition of the chlorosulfonic acid in one portion, the surface area of the acetanilide is reduced by melting it in the flask over a soft flame and then rotating the flask to spread the material in a thin film over the bottom lower 1/4 inch of the walls.
		Cool the flask in an ice bath and prepare a trap for the HCl that will be produced in the next step: tear a paper towel in half and roll it into the shape of a cigarette approximately 5 in.

	Acetanilide Procedure (Site not responding. Last check: 2007-10-18)
		Pour 3-4 mL of boiling water thru the fluted paper then filter your acetanilide mixture thru this warm funnel (3-4 mLs at a time).
		The key is to have the flask, filter, and paper hot.
		If too much mixture is filtered at a time the acetanilide will crystallize on the filter paper and more solvent will be required to re-dissolve which will decrease your final yield.

		DETERMINING THE MELTING RANGE Melting range of recrystallized acetanilide = 112 — 114 oC Melting range of impure acetanilide = 105 — 111 oC CONCLUSION: In this experiment a technique was used that will be used frequently throughout the semester: Purification by recrystallization.
		The purity of the material obtained can be correlated to the sharpness and veracity of the melting point data and this was observed.
		Mass of recovered acetanilide = 0.8575 g Mass of lost acetanilide = 1.4073 - 0.8575 = 0.5498 g 1) In the hot filtration step, material crystallized in filter paper.
