Some commercially significant derivatives: Amounts of acetic acid used in these other applications together account for another 5–10% of acetic acid use worldwide. As the demand for vinegar for culinary, medical, and sanitary purposes increased, vintners quickly learned to use other organic materials to produce vinegar in the hot summer months before the grapes were ripe and ready for processing into wine. Because H 3 O + concentration is known now, pH value of acetic acid solution can be calculated. Acetic acid that is manufactured by intent, rather than recovered from processing (such as the production of cellulose acetates, polyvinyl alcohol operations, and numerous acetic anhydride acylations).
