It´s produced from Bio-Ethanol, a renewable resource. It is a versatile intermediate with a variety of applications. DEA is used for the production of Diethylaminoethanole, a product used mainly in water treatment as corrosion inhibitor, for the production of DEET, a very well known insect repellent, for the production of rubber chemicals (e.g. Tetraethyl thiuram disulphide), for the production of hydroxylamine and various other chemicals and active pharma ingredients.
