Basic anhydrides are metal oxides (any metal ion bonded to the oxide ion) like MgO or Na2O. Metal oxides strip one of the hydrogens away from water, leaving an OH ion.
You get a polymer!
When you have ethylene glycol react with phtalic anhydride in a basic sollution such as NaOH(aq) you'll get a linear polymer.
When you have glycerol react with phtalic anhydride...
This is the parent acid of the anhydride CO2 --> finding the anhydride of a parent acid can be found by subtracting an H2O molecule from it (and vice versa to determine the parent acid of an...
