acid anhydride
A member of a class of organic compounds derived formally (but not in practise)
from carboxylic acids by the elimination
of water. Acid anhydrides have the general formula RCOOCOR' and are prepared
by reaction of an acid chloride with
a carboxylate. Chemically, acid anhydrides resemble acid
chlorides but are less violently reactive. They are used in the Friedel-Crafts
reaction and Diels-Alder reaction
and to make esters. Related
