Ethylene amines are particularly reactive molecules which have the ability to change the properties of a wide range of chemical products. They can make them softer, firmer or more flexible, make them adhere better or stop them from coagulating. Most of the ordinary products we use in our everyday lives — cosmetics, pharmaceuticals, paper rolls, paint, adhesives and detergents – can be manufactured using ethylene amines.

Ethylenediamine (EDA; 1,2-diaminoethane; CAS 107-15-3) is the ethyleneamine with the lowest molecular weight. It contains two primary amine groups and appears as a colorless liquid. Ethylenediamine is a highly reactive and versatile molecule. It is commonly used as an intermediary to produce detergents, paper chemicals, textile auxiliaries, fungicides and polyamides.

Diethylenetriamine (DETA; CAS 111-40-0) is another aliphatic ethylene amine with two primary and one secondary amine groups. Just like EDA, DETA presents itself as a clear, colorless liquid. Typical application areas of diethylenetriamine include chelating agents, wet-strength resins, lubricant oil additives, oil field chemicals and polyamides for resins or epoxy curing agents.

Aminoethylethanolamine (AEEA; CAS 111-41-1) is a linear molecule with primary and secondary amine groups. AEEA appears as a colorless liquid, but with slightly higher viscosity than EDA and DETA. Aminoethylethanolamine is an amine with unique characteristics and is commonly used as an intermediate in the fabrication of detergents, fabric softeners, chelates, fuel additives and coatings.

Piperazine (PIP; CAS 110-85-0) is a cyclic ethylene amine with two secondary amine groups. In its pure form, PIP has a freezing point of 110°C and a boiling point of 146°C. Due to its narrow liquid range, commercial piperazine is often supplied as 68 % active content diluted with water (PIP 68%). AkzoNobel supplies Piperazine 68 % and Piperazine 99 % – more commonly known as "anhydrous piperazine" or "piperazine flakes". Piperazine is commonly used as a raw material for several commercially available drugs. Other possible application fields include polyamides, gas sweetening and as an intermediate in PU catalysts.

Aminoethylpiperazine (AEP; CAS 140-31-8) is an ethylene amine with unique molecular structure, as it contains one primary, one secondary and one tertiary amine. AEP is a colorless liquid with a broad liquid range. This makes it a suitable raw material for a large variety of applications including corrosion inhibitors, urethane catalysts and epoxy hardeners.

N-Methylpiperazine (NMP; CAS 109-01-3) is another cyclic ethylene amine which appears as a clear, hygroscopic liquid. NMP is primarily used as raw material for pharmaceuticals.

Triethylenetetramine (TETA; CAS 90640-67-8 and 112-24-3) is a colorless to light-yellow liquid containing linear, branched and cyclic molecules. TETA is mainly used in the manufacture of fuel oil additives, lubricating oil additives and epoxy curing agents. It is also used in the production of asphalt additives.

Tetraethylenepentamine (TEPA; CAS 90640-66-7 and 112-57-2) is a yellowish liquid containing linear, branched and cyclic molecules. Like TETA, TEPA is commonly used as an additive in fuel and lubricating oil production, as an epoxy curing agent or in the manufacture of asphalt additives.

Amine Blends

Berolamine-20 (BA-20; CAS 68910-05-4) is a blend of higher polyethylene polyamines and alkanolamines. BA-20 is used as an intermediate in the manufacture of asphalt additives, in polyamide resins and corrosion inhibitors. It is also used as a cement grinding agent and flotation agent.

Berolamine-200 (BA-200; CAS 111-40-0 and 140-31-8) is an amine blend containing about 90 % DETA and 10 % AEP. BA-200 has been specifically designed as a building block for wet strength resins.

Berolamine-505 (BA-505; CAS 103-76-4/111-41-1/140-31-8) is an amine blend containing about 60% HEP, 15% AEP and 30% AEEA. BA-505 is commonly used as an asphalt additive.

XA-70 (CAS 84238-53-9) is a polyamine blend with unique characteristics. XA-70 has been developed specifically as an epoxy curing agent but its usage can be extended to mineral processing aids and corrosion inhibitors.
