Acetic anhydride in a glass bottle. Acetic anhydride, like most acid anhydrides, is a flexible molecule with a nonplanar structure. [4] The pi system linkage through the central oxygen offers very weak resonance stabilization compared to the dipole-dipole repulsion between the two carbonyl oxygens. The energy barriers to bond rotation between ...
In the laboratory, it can be easily synthesized from anthranilic acid and acetic anhydride. N -Acetylanthranilic acid exhibits triboluminescence when crushed. [ 5 ] The fractured crystals have large electrical potentials between areas of high and low charge.

Acetylated wood is a type of modified wood that is produced through a chemical modification process and does not contain any toxic substances. [1] It produced from a chemical reaction (named as acetylation), involving acetic anhydride and a modification process to make wood highly resistant to biological attacks by fungi and wood-boring insects and durable to environmental conditions.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
Acetic acid, antimony(3+) salt ... data are given for materials in their standard state ... oxide with acetic anhydride: Sb 2 O 3 + 3 C 4 H 6 O 3 → 2 Sb(CH 3 CO 2) 3.
Acetanilide can be produced by reacting acetic anhydride with aniline: [7]. C 6 H 5 NH 2 + (CH 3 CO) 2 O → C 6 H 5 NHCOCH 3 + CH 3 COOH. The preparation used to be a traditional experiment in introductory organic chemistry lab classes, [8] but it has now been widely replaced by the preparation of either paracetamol or aspirin, both of which teach the same practical techniques (especially ...
Thioacetic acid is prepared by the reaction of acetic anhydride with hydrogen sulfide: [5] (CH 3 C(O)) 2 O + H 2 S → CH 3 C(O)SH + CH 3 C(O)OH. It has also been produced by the action of phosphorus pentasulfide on glacial acetic acid, followed by distillation. [6] CH 3 C(O)OH + P 2 S 5 → CH 3 C(O)SH + P 2 OS 4. Thioacetic acid is typically ...
