	Chemical of the Week -- Acetic Acid and Acetic Anhydride
		Glacial acetic acid boils at 118°C, and has a density of 1.049 g/mL at 25°C. It is flammable with a flash point of 39°C. Through hydrogen-bonding interactions, acetic acid is miscible (mixable) in all proportions with water, ethyl alcohol, and diethyl ether.
		Acetic anhydride is a clear, colorless, mobile (free-flowing) liquid with a sharp odor similar to that of acetic acid.
		Acetic anhydride melts at —73°C, boils at 139°C, and has a density of 1.080 g/mL at 15°C. It is flammable with a flash point of 54°C. This compound is readily combustible and represents a fire hazard.

	Acetic Anhydride
		Acetic acid anhydride, acetic oxide, acetyl oxide, ethanoic anhydride, acetyl ether.
		Acetic anhydride is a colorless liquid with a strong, pungent odor.
		Before a worker is placed in a job with a potential for exposure to acetic anhydride, the examining physician should evaluate and document the worker's baseline health status with thorough medical, environmental, and occupational histories, a physical examination, and physiologic and laboratory tests appropriate for the anticipated occupational risks.

		Acetic acid occurs ubiquitously and is a normal metabolite in animals; therefore, the general population is continually exposed to the compound.
		Vapor-phase acetic acid is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 22 days(3,SRC).
		Acetic acid concns were measured in smoke condensates of Ponderosa pine wood (4.4 g/kg smoldering; 0.34 g/kg flaming), needles (7.6 g/kg smoldering), bark (5.4 g/kg smoldering; 3.3 g/kg self-substained smoldering), litter (2.4 g/kg smoldering; 1.3 g/kg self-substained smoldering), duff (0.85 g/kg smoldering; 0.66 g/kg self-substained smoldering), and humus (0.19 g/kg smoldering)(4).

	biology - Acetic acid
		Acetic acid is a molecule central to biochemistry, and is produced in some amount by nearly all forms of life.
		Acetic acid, when complexed with coenzyme A, is central to the metabolism and biosynthetic processes of almost all forms of life.
		Acetic acid-producing bacteria are universally present, and any culture practicing the brewing of beer or wine inevitably discovered vinegar as the natural result of these alcoholic beverages being exposed to air.

	The Recovery of Acetic by Liquid-Liquid Extraction
		Acetic acid is one of the most widely used carboxylic acids, It is used in many reactions, for example, the synthesis of acetic esters, or it can be used as a solvent, for example, in the manufacture of cellulose acetate or pharmaceutical products.
		Acetic acid is extracted from water by a suitable solvent in order to obtain substantially pure acetic acid.
		Recovery of the highest concentration acetic acid is only possible if the feed to the rectification stage lies on the line between the azeotrope point AZ and pure acetic acid E. On the other hand, since the point should also lie on the ternary equilibrium curve, only the point SA corresponds to these conditions.

	Photographic Chemical Descriptions
		Photographic grade acetic acid is 28% because glacial acetic acid cannot be added to sodium sulfite without decomposing the sulfite to form sulfur dioxide gas.
		White vinegar is a dilute solution of acetic acid, usually 3 to 6% acetic acid, although distilled vinegar may have a higher acid content.
		Glacial acetic acid may be diluted to 28 percent by mixing 3 parts of Glacial acetic acid with 8 parts of water.

	Acetic acid (vinegar) for weed control revisited
		Teasdale suggested that the mechanism of action of acetic acid is similar to that of paraquat in that acetic acid causes the rapid dissolution of cell membrane integrity, resulting in the desiccation of foliar tissues, and ultimately plant death.
		Acetic acid is nonselective and may damage any plant part contacted by the material.
		Acetic acid concentrations from 10 to 20 percent controlled 80 to 100 percent of the smaller weeds, as reported in the USDA release.
