Aliphatic Amines and their Modifications Aliphatic ethylene amines were the first amine hardeners used in epoxy coatings. They are simple commodity chemicals that were available to react with epoxies. They include aminoethyl piperazine (AEP),
Chemistry Notes for class 12 Chapter 13 Amines
ncerthelp.comBasic Strength of Amines Amines act as Lewis bases due to the presence of lone pair of electrons on the nitrogen atom. More the K b (dissociation constant of base), higher is the basicity of amines. Lesser the pK b‘ higher is the basicity of amines. Aliphatic amines (CH 3 NH 2) are stronger bases than NH 3 due to the electron releasing +/ effect

ncert.nic.inLower aliphatic amines are soluble in water because they can form hydrogen bonds with water molecules. However, solubility decreases with increase in molar mass of amines due to increase in size of the hydrophobic alkyl part. Higher amines are essentially insoluble in water.
