  2. Base anhydride - Wikipedia

    en.wikipedia.org/wiki/Base_anhydride

    A base anhydride is an oxide of a chemical element from group 1 or 2 (the alkali metals and alkaline earth metals, respectively). They are obtained by removing water from the corresponding hydroxide base. If water is added to a base anhydride, a corresponding hydroxide salt can be [re]-formed.

  3. Basic oxide - Wikipedia

    en.wikipedia.org/wiki/Basic_oxide

    A basic oxide, also called a base anhydride (meaning "base without water"), is usually formed in the reaction of oxygen with metals, especially alkali (group 1) and alkaline earth (group 2) metals. Both of these groups form ionic oxides that dissolve in water to form basic solutions of the corresponding metal hydroxide:

  4. Acetic anhydride - Wikipedia

    en.wikipedia.org/wiki/Acetic_anhydride

    Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O. Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid, which is formed by its reaction with ...

  5. Organic acid anhydride - Wikipedia

    en.wikipedia.org/wiki/Organic_acid_anhydride

    A common type of organic acid anhydride is a carboxylic anhydride, where the parent acid is a carboxylic acid, the formula of the anhydride being (RC(O)) 2 O. Symmetrical acid anhydrides of this type are named by replacing the word acid in the name of the parent carboxylic acid by the word anhydride. [2] Thus, (CH 3 CO) 2 O is called acetic ...

  6. Di-tert-butyl dicarbonate - Wikipedia

    en.wikipedia.org/wiki/Di-tert-butyl_dicarbonate

    Di-tert-butyl dicarbonate is a reagent widely used in organic synthesis. [1]Since this compound can be regarded formally as the acid anhydride derived from a tert-butoxycarbonyl (Boc) group, it is commonly referred to as Boc anhydride.

  9. Acid anhydride - Wikipedia

    en.wikipedia.org/wiki/Acid_anhydride

    Organic acid anhydrides often form when one equivalent of water is removed from two equivalents of an organic acid in a dehydration reaction. In inorganic chemistry, an acid anhydride refers to an acidic oxide, an oxide that reacts with water to form an oxyacid (an inorganic acid that contains oxygen or carbonic acid), or with a base to form a ...
