As an anhydride, It can be prepared by dehydrating its acid, i.e. Acetic acid, by strong dessicant such as Tetraphosphorus decaoxide (P4O10) : P4O10 + 12 CH3COOH ----> 4 H3PO4 + 6 (CH3CO)2O

acetic acid
Chloroacetic acid is stronger, because it contains (more electronegative) chlorine atoms in the place of (less electronegative) hydrogen atoms.
Glacial acetic acid is simply pure or very nearly pure acetic acid. It's formula would simply be CH3CO2H.
