Acetic Anhydride Production Process
Glacial acetic acid is a concentrated form of the organic acid which gives vinegar its sour taste and pungent smell and it is also an important reagent during the production of organic compounds. A dilute approximately 5 percent by volume solution of acetic acid produced by fermentation and oxidation of natural carbohydrates is called vinegar.
