	Acetic acid - Wikipedia, the free encyclopedia
		Acetic acid is corrosive, and its vapour is irritating to eyes and nose, although it is a weak acid based on its ability to dissociate in aqueous solutions.
		Acetic acid is also a component of the vaginal lubrication of humans and other primates, where it appears to serve as a mild antibacterial agent.
		Equivalently, acetic acid is used as a spray-on preservative for livestock silage, to discourage bacterial and fungal growth.

	Acetic acid bacteria - Wikipedia, the free encyclopedia
		Acetic acid bacteria are bacteria that derive their energy from the oxidation of ethanol to acetic acid during respiration.
		The acetic acid bacteria are found in nature where ethanol is being formed as a result of yeast fermentation of sugars and plant carbohydrates.
		In these liquids the acetic acid bacteria grow as a surface film due to their aerobic nature and active motility.

	Chemical of the Week -- Acetic Acid and Acetic Anhydride
		Acetic acid is the chemical compound responsible for the characteristic odor and sour taste of vinegar.
		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.

	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.

	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.

		Comments Acetic acid has a sufficiently acid taste to limit the amount used in foods.
		In evaluating the acceptance of acetic acid, emphasis is placed on its established metabolic pathways and its normal consumption by man. Evaluation For purposes of evaluation all sources of acetate used as food additives should be considered together.
		Since acetic acid has a sufficiently acid taste to limit the amount used in foods, it is not necessary to indicate acceptable daily intakes for man. REFERENCES Dreyfus, L. Compt.
