Ethylenediamine (EDA) CAS 107-15-3

Product Overview

Ethylenediamine is provided as a basic diamine intermediate for industrial manufacturing routes that require strong amine reactivity and coordination capability. It is commonly selected for chelating agent synthesis and for process systems involving stepwise condensation or amine-based downstream transformation.

Industrial uses include chelating-agent and agrochemical synthesis, polyamide resin production and chain extension in waterborne polyurethane dispersions. The required EDA concentration and water limit depend on the reaction and downstream process.

Product Information / Specifications

Physical & Chemical Properties

We provide the TDS for the EDA grade we supply, with the concentration, test temperatures and methods relevant to its physical properties. Values for neat ethylenediamine should not be applied directly to aqueous solutions at different concentrations.

EDA Quality Tests and Purchasing Specifications

For EDA quotations, specify the assay and reporting basis, water limit, color and relevant amine impurities. Gas chromatography (GC) is used for assay and impurity analysis; a GC area percentage is not automatically a mass percentage. Compare results only when the method and calculation basis are compatible.

Water methods for EDA include GC with thermal conductivity detection (GC-TCD) and supplier-validated Karl Fischer methods. State the method and reporting basis on the specification. For APHA/Hazen color, also specify whether the sample is neat or diluted and the test temperature. Amine value measures total basicity and does not replace a composition-specific assay.

Applications

• Chelating agent synthesis and related intermediate manufacturing
• Agrochemical intermediate processing
• Specialty chemical synthesis requiring reactive diamine functionality
• Resin, coating, and auxiliary chemical manufacturing routes
• Selected surfactant and process chemical applications where amine reactivity is required

For higher amine functionality in resin or chelating-agent synthesis, compare Diethylenetriamine (DETA) and Tetraethylenepentamine (TEPA). Their molecular weight and reactive-group equivalents differ from EDA; they are not equal-weight replacements.

Where hydroxyl functionality is also needed, Aminoethylethanolamine (AEEA) is a related aminoalcohol to evaluate. For higher ethyleneamine mixtures, compare Polyethylene Polyamine (PEPA) by composition, amine value, amine hydrogen equivalent weight and viscosity rather than treating it as a single-component EDA grade.

Packaging

EDA packaging and transport arrangements are specified in our quotation for the selected concentration, quantity and destination.

Storage Conditions

• Store in a cool, dark, and sealed place.
