Diels-Alder
Trifluoromethanesulfonic anhydride = (CF3SO2)2O
The succinic anhydride amine reaction involves the reaction between succinic anhydride and an amine compound. This reaction forms a cyclic intermediate, which then undergoes ring-opening to produce a succinimide product. This reaction is important in organic synthesis for the formation of amide bonds, which are crucial in the production of various pharmaceuticals and polymers.
An acid anhydride is an organic compound that has two acyl groups bound to the same oxygen atom. Usually, the acyl groups come from the same caboxylic acid, he formula for the anhydride being (RC(O))2O + H2O
Acetic anhydride is a liquid at room temperature. It is a colorless, corrosive liquid with a pungent vinegar-like odor. It is commonly used in organic synthesis reactions.
The reaction between methylamine and acetic anhydride results in the formation of N-methylacetamide as the primary product. In this reaction, acetic anhydride reacts with methylamine to form an amide functional group. This reaction is a common method for the synthesis of amides in organic chemistry.

Acetanilide can also be synthesized by reacting aniline with acetic anhydride, instead of acetyl chloride. This is known as the Acetic Anhydride Method.
The main impurties are probably the unreacted reactants. i.e salicylic acid and some acetic anhydride (ethanoic anhydride)
The product of the reaction between anthracene and maleic anhydride is known as anthracene-maleic anhydride adduct. This adduct is commonly used in the synthesis of dyes, polymers, and other organic compounds.
The reaction is: (CH3CO)2O + H2O = 2 CH3COOH

Synthesis of acetyl chloride via the reaction of acetic acid with sulphuric acid
Acetic anhydride is a liquid at room temperature. It is a colorless, corrosive liquid with a pungent vinegar-like odor. It is commonly used in organic synthesis reactions.
Aspirin is generally produced by the following mechanism (starting from basic materials) Phenol --(NaOH, CO2, heat)--> Sodium Salicylate (+para isomer) --(H2SO4)--> Salicylic acid --(acetic anhydride)--> acetylsalicylic acid (Aspirin) Due to the myriad of organic reactions, there are multiple possibilities at each stage. However, the above is the most efficient and common way of synthesizing Aspirin. For example, the last reaction (esterification) may be accomplished by using an acyl halide instead of an anhydride (e.g. ethanoyl/acetic chloride instead of acetic anhydride). However, the acyl halide is more costly to synthesize and more unstable to handle.
The reaction between methylamine and acetic anhydride results in the formation of N-methylacetamide as the primary product. In this reaction, acetic anhydride reacts with methylamine to form an amide functional group. This reaction is a common method for the synthesis of amides in organic chemistry.
Adding a small amount of acetic anhydride helps to facilitate the acetylation reaction with aniline, leading to the formation of acetanilide. The acetic anhydride serves as an acetylating agent that transfers an acetyl group to the amine group of aniline, resulting in the desired product. The use of an excess of acetic anhydride is avoided to prevent side reactions and to optimize the yield of acetanilide.
