General
-
Diethylamine is a secondary amine with the molecular structure
CH3CH2NHCH2CH3.
- It is a
flammable, strongly alkaline liquid. It is miscible with water and
ethanol.
- As a liquid
it has a dark brown color due to impurities, however when distilled it is
colorless.
- It is
volatile and has a strong unpleasant odor.
Process
-
Diethylamine is manufactured from ethanol and ammonia and is obtained
together with ethylamine and triethylamine.
- Three
secondary amines, N-methylaniline, diisopropylamine and diethylamine, were
reacted with carbon disulfide in the presence of diethylzinc to yield the
corresponding bis (dialkylamidodithio-carbamato) zinc complexes ranging
from 10 to 24%.
Report
-
N,N-diethyl-m-toluamide (DEET) is the active ingredient in most topical
insect repellent products.
-
Approximately 30% of the U.S. population use DEET-containing products, and
domestic usage of DEET is estimated to be 1800 tonnes annually.
Application
- It is used
as a corrosion inhibitor and in the production of rubber, resins, dyes and
pharmaceuticals.
- Nitrogen
containing polymers / copolymers were prepared to act for corrosion
protection.
- They
are based on glycidylmethacrylate and or diethylamino–ethylmethacrylate.
