Chemistry Solutions & Suspensions Project Acetic Acid (Ethanoic Acid) Acetic Acid is a type of acid that is the main component of vinegar, with the chemical formula of CH3COOH. It is colourless and has a sour taste. Despite its status as a weak acid, it is corrosive when concentrated. Apart from being used to produce household vinegar, it is also used to produce Polyvinyl Acetate for wood glue and Cellulose Acetate for photographic film, together with various other synthetic fabrics and fibres. Its esters are also used as solvents for inks, coatings and paints. Mechanism of Acetic Acid Acetic Acid is produced through a process called Methanol Carbonylation where Methanol and Carbon Monoxide react, resulting in Acetic Acid’s production, as demonstrated in the equation below: CH3OH + CO → CH3COOH Another method of using Methanol Carbonylation to produce Acetic Acid requires an intermediate – iodomethane – and a catalyst – Metal Carbonyl, for carbonylation. The equation used for this process is as follows: CH3OH + HI → CH3I + H2O CH3I + CO → CH3COI CH3COI + H2O → CH3COOH + HI There are other methods used in the production of Acetic Acid, though they are not as popular as Methanol Carbonylation, as listed below: Acetaldehyde Oxidation Ethylene Oxidation Oxidative Fermentation Anaerobic Fermentation References: Wikipedia, the free encyclopaedia Credits: Jimmy Donal Wales Sir Timothy John Berners-Lee Glossary: Polyvinyl Acetate (PVA) – A rubbery synthetic polymer Cellulose Acetate – The acetate ester of cellulose Ester – Chemical compounds consisting of an ether linkage adjacent to a carbonyl Methanol – By-product of the destructive distillation of wood Carbon Monoxide – A colourless, tasteless and odourless gas that is less dense than air Intermediate – A molecular entity that is formed from the reactants
