Theoretical studies of mechanisms of epoxy curing systems

reaction with carboxylic acids is more complex than currently known Reactions between epoxy and anhydride s often require a tertiary amine (R 3N) Lewis base as the catalyst Previous studies mutually agreed the mechanism is an anionic one However Fischer suggested R 3N opens anhydride first to for m a zwitterion which can then undergo

What happens when amines react with carboxylic acids?

The reaction between amines and carboxylic acids to form amides is biologically important. It is through this reaction that amino acids (molecules containing both amine and carboxylic acid substituents) link together in a polymer to form proteins. What happens when amines reacts with carboxylic acid? Why do amines not react with carboxylic acids?

Can tertiary amines be acylated?

Tertiary amines cannot be acylated due to the absence of a replaceable hydrogen atom. With the much less active benzoyl chloride, acylation can still be performed by the use of excess aqueous base to facilitate the reaction. Because amines are basic, they neutralize carboxylic acids to form the corresponding ammonium carboxylate salts.

How do acyl chlorides and acid anhydrides react with amines?

Acyl chlorides and acid anhydrides react with primary and secondary amines without the presence of heat to form amides. Tertiary amines cannot be acylated due to the absence of a replaceable hydrogen atom. With the much less active benzoyl chloride, acylation can still be performed by the use of excess aqueous base to facilitate the reaction.

What happens to amine salts when heated to 200°C?

Upon heating to 200°C, the primary and secondary amine salts dehydrate to form the corresponding amides. Amines R 3 N react with strong acids such as hydroiodic acid (HI), hydrobromic acid (HBr) and hydrochloric acid (HCl) to give ammonium salts R 3 NH +. Nitrous acid with the chemical formula HNO 2 is unstable.
