Description

General description

Ethylenediamine (en) is a linear aliphatic diamine. The synthesis of ethylenediamine has been reported. Its effect as an allergen has been investigated. It participates in the synthesis of metal chalcogenides and thiogallates.

Application

Ethylenediamine (en) is suitable for use in the synthesis of covalently linked adducts of deoxyribonucleic acid (DNA) oligonucleotides with single-walled carbon nanotubes. It may be used in the following studies:

• Functionalization of the triazolate-bridged metal-organic framework.
• As a solvent in the synthesis of ZnS and ZnSe precursors by solvothermal process.
• As a softening agent for hard wood plant structure.
• As a reactant in the synthesis of Pd/C-ethylenediamine complex catalyst.
• As a chelating agent in the synthesis of β-Co(OH)₂ nanocrystals.
• To produce ethylenediamine modified rice hull, used as a sorbent for basic and reactive dyes.
• Synthesis of ethylenediamine-templated iron arsenates and fluoroarsenates.
• As a template agent and coordination agent in the synthesis of CdS nanocrystals.
• As a reagent in the synthesis of imidazolines.
