Prof. Shakhashiri www.scifun.org General Chemistry ACETIC ACID & ACETIC ANHYDRIDE Acetic acid is the chemical compound responsible for the characteristic odor and sour taste of vinegar. Typically, vinegar is about 4 to 8% acetic acid. As the defining ingredient of vinegar, acetic acid has been produced and used by humans since before the dawn of recorded history. In fact, its name comes from the Latin for vinegar, acetum. Vinegar is formed from dilute solutions of alcohol, such as wine

(methanol and dimethyl ether) by indirect coal liquefaction (ICL). Gasification of coal produces a synthesis gas that can be converted to liquid fuel by synthesis over appropriate catalysts. Recycling of unconverted synthesis gas back to the synthesis reactor enables a larger fraction of the coal energy to be converted to liquid fuel. Passing synthesis gas once over the synthesis catalyst, with unconverted synthesis gas used to generate electricity in a gas turbine combined cycle, leads to less liquid fuel

range of food and pharmaceutical applications. It is used by the food industry as a soluble dietary fibre and fat or sugar replacement, and in the pharmaceutical industry as a stabiliser and excipient. It can also be used as a precursor in the synthesis of a wide range of compounds. New uses for inulin are constantly being discovered, with recent research into its use for slow-release drug delivery. Inulin, when in a particulate form, possesses anti-cancer and immune enhancing properties. Given
