What is an acetic anhydride screening assessment?

The Government conducted a science-based evaluation of acetic acid, anhydride (acetic anhydride), called a screening assessment, to address the potential for harm to Canadians and to the environment.

What are acid anhydrides?

Acid anhydrides are compounds that turn into an acid when you add water. They are non-metal oxides. The oxides of period three elements demonstrate periodicity with respect to acidity. As you move across the period, the oxides become more acidic. Sodium and magnesium oxides are alkaline.

How do anhydrides react with water?

Anhydrides are highly reactive to nucleophilic attack and undergo many of the same reactions as acid chlorides that were explored in section 21.4. Although slower reacting than acid chlorides, anhydrides react with water to form carboxylic acids, with alcohols to form esters, and with amines to form amides.
