What is the by product in reaction amination of ethylene dichloride?

Production. There are two main routes for the production of ethyleneamines, the reaction between ethylene dichloride and ammonia, and the reductive amination of monethanolamine. In the ethylene dichloride route, the initial product of this reaction is ethylenediamine.

Does thiotepa cause hair loss?

Since the growth of normal body cells may also be affected by thiotepa, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, like hair loss, may not be serious but may cause concern. Some effects do not occur for months or years after the medicine is used.

Is Ethyleneamine a base?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C2H4(NH2)2. This colorless liquid with an ammonia-like odor is a basic amine.

What type of ligand is ethylenediamine?

– Ethylenediamine is an example of bidentate ligand. This means that ethylene diamine has two donor atoms. It means that it can bind with the central metal ion with two nitrogen atoms. The bidentate ligands are also known as chelating ligands.

How is Tepa used in lubricating oil production?

Tetraethylenepentamine (TEPA) is a yellowish liquid containing linear, branched and cyclic molecules. 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.

Is the color of Tepa a colorless liquid?

Tetraethylenepentamine ( TEPA) is an organic compound and is in the class of chemicals known as ethyleneamines. It is a slightly viscous liquid and is not colorless but, like many amines, has a yellow color. It is soluble in most polar solvents. Diethylenetriamine (DETA), triethylenetetramine (TETA), piperazine,…

What kind of solvent is Tepa soluble in?

It is soluble in most polar solvents. Diethylenetriamine (DETA), triethylenetetramine (TETA), piperazine, and aminoethylpiperazine are also usually present in commercial available TEPA. The reactivity and uses of TEPA are similar to those for the related ethylene amines ethylenediamine and diethylenetriamine and triethylenetetramine.

How is tetraethylenepentamine used as a curing agent?

It is primarily used as a curing agent or hardener in epoxy chemistry. This can be on its own or reacted with tall oil fatty acid (TOFA) and its dimer to make an amidoamine. This amidoamine is then used as the curing agent for epoxy resin systems.
