Descrizione

Descrizione generale

Ethylenediamine (en) is a linear aliphatic diamine. The synthesis of ethylenediamine has been reported.[1] Its effect as an allergen has been investigated.[2] It participates in the synthesis of metal chalcogenides[3] and thiogallates.[4]

Applicazioni

Ethylenediamine (en) is suitable for use in the synthesis of covalently linked adducts of deoxyribonucleic acid (DNA) oligonucleotides with single-walled carbon nanotubes.[5] It may be used in the following studies:

• Functionalization of the triazolate-bridged metal-organic framework.[6]
• As a solvent in the synthesis of ZnS and ZnSe precursors by solvothermal process.[7]
• As a softening agent for hard wood plant structure.[8]
• As a reactant in the synthesis of Pd/C-ethylenediamine complex catalyst.[9]
• As a chelating agent in the synthesis of β-Co(OH)₂ nanocrystals.[10]
• To produce ethylenediamine modified rice hull, used as a sorbent for basic and reactive dyes.[11]
• Synthesis of ethylenediamine-templated iron arsenates and fluoroarsenates.[12]
• As a template agent and coordination agent in the synthesis of CdS nanocrystals.[13]
• As a reagent in the synthesis of imidazolines.[14]
