Acetic acid can be oxidized to acetaldehyde by air, oxide by ethanol (ethyl alcohol) and acid by butane and butane in industry. Today, vinegar is produced from the reaction between methanol and carbon monoxide by a rhodium-ion iodine catalyst developed by Monsanto in the 1960s. This method is cost-effective because methanol and carbon monoxide are cheap and cost-effective.
Heat butane with oxygen in the presence of manganese, cobalt and chromium metal ions that produce peroxide, which produces acetic acid by decomposition of acetic acid.
Acetaldehyde is oxidized by air to form acetic acid under mild conditions in the presence of simple metal catalysts such as manganese and chromium.
2CH3CHO + 2O2-----> 2CH3COOH
This reaction also brings with it by-products, which include formic acid, acetyl acetate, and due to their low boiling point, acetic acid can be separated by distillation. Acetic acid is one of the most important chemicals in the world and one of the main raw materials for the production of vinyl acetate monomer (VAM), acetic anhydride and ester acetate such as ethyl acetate (used for adhesives, inks and cosmetics), isopropyl acetate. (Used in printing inks and coatings), n-butyl acetate (printing, adhesives and cosmetics). Acetic acid is commonly used to produce terephthalic acid (PTA) profiles, which can be reused to produce polyethylene terephthalate (PET). PET is used in packaging, photographic films and magnetic parts, for polyester fibers and in glass and other liquids.
Acetic acid should be stored away from heat or other sources of combustion. Keep away from incompatible substances including oxidizing agents, reducing agents, metals, acids and alkalis. Store acetic acid in a cool, well-ventilated place in a tightly packed container.
