Diethylenetriamine (DETA)
Diethylenetriamine (CAS #000111-40-0, N-(2-aminoethyl)-1,2-ethanediamine) is the next-to lowest molecular weight product containing two primary and one secondary nitrogen. Clear and colorless with an ammonia-like odor, DETA is a single component product.
Diethylenetriamine finds uses in such diverse areas as a collector that enhances flotation separation, for use in the collection of iron and other metals, and in certain types of ores including gold and pyrite. Also used as a concrete anti-shrinking agent which reduces surface tension and minimizes shrinkage/cracking as water evaporates from concrete. It is also a building block for asphalt modification additives and in the manufacture of imidazoline based corrosion inhibitors.
