According to the literature, it is known that:
" Diethylamine is a secondary amine with the molecular structure CH3CH2NHCH2CH3. It is a flammable, strongly alkaline liquid. It is miscible with water and ethanol. It is a colorless liquid which often appears brown due to impurities. It is volatile and has a strong unpleasant odor... "
Does anyone know or suggest me any secure method which can be used to dry diethylamine?
