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

∙ 13y agoSince vinegar is dilute, first we have to boil it to make it concentrated. When acid is about 97% , keep it with phosphoric anhydride. As a powerful desiccant it will dehydrate Concentrated acetic acid into Acetic anhydride.

∙ 13y agoAdd 1 part glacial acetic acid TO 9 parts water. Be aware that glacial acetic acid is a strong acid and can burn you. If you add water to acid, it can react violently.
I find it more convenient to buy glacial acetic acid then dilute it because I use it alot for cleaning and pickling and it takes up less space. Also some of my pickling recipes use glacial acetic acid straight. Check you have food grade acid if using it for pickling.

What would happen if the excess acetic anhydride is not removed in the reaction vessel?
If the excess acetic anhydride is not removed in the reaction vessel an unwanted reaction will occur. The acetic anhydride will react causing esterification.
Why add of little amount from acetic anhydride in synthesis of acetanilide?
Acetic anhydride and aniline are the reactants for the preparation of acetaanilide.
Reaction of methyl amine and acetic anhydride?
No it is not among these.
Is acetic anhydride powder or liquid?
Liquid
What are the compound names for salicylic acid and acetic anhydride?
Your question has the names right in it. Maybe it's the chemical formulas you want. In that case, salicylic acid is C7H6O3 and acetic anhydride is C4H6O3.
Is acetic anhydride an acid or a base?
An anhydride is not an acid and not a base.
What would happen if the excess acetic anhydride is not removed in the reaction vessel?
If the excess acetic anhydride is not removed in the reaction vessel an unwanted reaction will occur. The acetic anhydride will react causing esterification.

Acetic anhydride and aniline are the reactants for the preparation of acetaanilide.
What is the reaction when zinc acetic anhydride and glacial acetic acid are combine?
Acetanilide
Why acetic anhydride used instead of acetic acid to prepare aspirin?
The -OH in acetic acid is not a very good leaving group so converting it to an ester is more complicated unlike acetic anhydride which is easier to do so.
Acetic anydryd to acetic cloride?
To get acetyl chloride, you need to react ethanoyl ethanoate and acetic acid anhydride.
Is acetic anhydride powder or liquid?
Liquid
Reaction of methyl amine and acetic anhydride?
No it is not among these.
In the preparation of aspirin water is added to the reaction flask Why?
The formation of aspirin will proceed faster if acetic anhydride is used in place of acetic acid. However, acetic anhydride will hydrolyze in the presence of water to form acetic acid, slowing down the reaction.
How can we react dehydrating agent with acetic acid?
Dehydration of acetic acid to prepare acetic anhydride occur at 8oo oC.
What are the compound names for salicylic acid and acetic anhydride?
Your question has the names right in it. Maybe it's the chemical formulas you want. In that case, salicylic acid is C7H6O3 and acetic anhydride is C4H6O3.
What is acetolysis?
Acetolysis is the process of the breakdwon of an organic compound using either acetic acid or acetic anhydride.
