Etilendiamin (bir ligand olduğunda en çok kısaltılan) C2H4 (NH2) 2 formülüne sahip organik bileşiktir. Amonyak benzeri bir koku içeren bu renksiz sıvı güçlü bir baz amindir. 1998 yılında yaklaşık 500.000 ton üretilen, kimyasal sentezde yaygın olarak kullanılan bir yapı taşıdır. Etilen diamin, nemli havada neme karşı kolayca reaksiyona girerek aşındırıcı, toksik ve tahriş edici bir sis üretir; buna kısa maruz kalmalar bile sağlıkta ciddi hasarlara neden olabilir (bkz. Güvenlik).
Etilendiamin (CAS # 000107-15-3, 1,2-diaminoetan) en düşük molekül ağırlıklı etilendiamindir. İki primer azot içeren tek bileşenli bir üründür. Amonyak benzeri bir koku vardır ve berraktır ve renksizdir.

ABSTRACT
Ethylene diamine tetra acetic acid (EDTA) is an effective chelating agent and lubricant. EDTA was thought to chemically soften the root canal dentin and dissolve the smear layer and increase dentin permeability. EDTA reacts with the calcium ions in dentin and forms soluble calcium chelates. For removing inorganic and organic material of smear layer, combined using EDTA and NaOCl is recommended. In this article, the usage and efficacy of EDTA in endodontic therapy are discussed. The aim of this review is s to analyze the relevant literature on EDTA.

Ethylenediamine tetraacetic acid grafted onto chitosan was shown to increase the antibacterial activity of chitosan via magnesium complexation, thereby destabilizing the membrane of Gram negative bacteria (El-Sharif and Hussain, 2011; Valenta et al., 1997). The grafting polymerization of dicyandiamide (DCDA) onto chitosan resulted in the synthesis of a water-soluble derivative that displayed antibacterial activity at pH of 7 and 4 when tested against E. coli and S. aureus (Khalil et al., 2015).
Ethylenediamine, H2NCH2CH2NH2, (abbreviated as en in writing formulas for complexes) forms many stable complexes with metal ions. One such complex is [Pt(en)2]2+. The amide ion will remove protons from the coordinated en so in liquid ammonia the reaction

The deprotonated species undergoes a reaction with methyl chloride,Ethylenediamine plays an essential role in the formation of crystalline ZnO. Zinc-ethylenediamine complex forms in the solution as shown by Eq.Ethylenediamine is a common aliphatic chain chelate and it forms very stable chelating compounds with a variety of transition metals. Howe and Lunsford [123] incorporated Co(II)-ethylenediamine complex into zeolites X and Y to form composite compounds that can adsorb oxygen. In both zeolite cages the oxygen adduct [Co(II)](en)2O2]2- may be formed and this complex adduct is stable up to 70°C in the presence of oxygen.

Synthesis
Ethylenediamine is manufactured by reacting ammonia and 1,2-dichloroethane. The reaction yields the mixture of ethylenediamine and the linear polyamines. A simplified equation would be:
ClCH2CH2Cl + 4 NH3 → H2NCH2CH2NH2 + 2 NH4Cl
Applications
Ethylenediamine is used in large quantities for production of many industrial chemicals. It forms derivatives with carboxylic acids (including fatty acids), nitriles, alcohols (at elevated temperatures), alkylating agents, carbon disulfide, and aldehydes and ketones. Because of its bifunctional nature, having two amines, it readily forms heterocycles such as imidazolidines.
Precursor to chelating agents
The most prominent derivative of ethylenediamine is EDTA, which is derived from ethylenediamine via a Strecker synthesis involving cyanide and formaldehyde. Hydroxyethylethyelenediamine is another commercially significant chelating agent. The salen ligands, derived from the condensation of salicaldehydes and ethylenediamine, are popular chelating agents in the research laboratory although not commercially significant.[1]
Precursor to pharmaceuticals and agrichemicals
Numerous bio-active compounds contain the N-CH2-CH2-N linkage, including aminophylline and some antihistamines.[2] Salts of ethylenebisdithiocarbamate are commercially significant fungicides under the brandnames Maneb, Mancozeb, Zineb, and Metiram. Some imidazoline-containing fungicides are derived from ethylenediamine.[1]

Ethylenediamine (most abbreviated containing a ligand) ethylenediamine is an organic compound with the formula 2 C2H4 (NH2). This colorless liquid with an ammonia-like fragrance is a strong base amine. It is a building block widely used in chemical synthesis, under approximately 500,000 tons in 1998. Ethylene diamine is a corrosive, toxic and irritating mist by reacting; security can cause short damage (see Security).
Ethylenediamine (CAS # 000107-15-3, 1,2-diaminoethane) is the lowest molecular weight ethylenediamine. It is a one-component product containing two primary nitrogen. It has an ammonia-like odor and is clear and colorless.
Applications
Ethylene diamine is ethylenediamine used in large quantities for the production of most industrial chemicals. It consists of carboxylic acids (including fatty acids), nitriles, alcohols (at high temperatures), alkylating agents, carbon disulfide and aldehydes and derivatives with ketones. Due to their binary details, two amines are available, they have heterocycles such as imidazolidines.
Pioneer of chelation agents, medicines and agrochemicals
The most prominent derivative of ethylene diamine is EDTA, which is ethylenediamine derived from ethylenediamine by Strecker synthesis containing cyanide and formaldehyde. Hydroxyethylethylenediamine is an important commercial chelating agent. Contains N-CH2-CH2-N bond. Salts of ethylenebisdithiocarbamate, commercial activity under the brands Maneb, Mancozeb, Zineb and Metiram are important fungicides. Some imidazoline-containing fungicides are non-specific from ethylenediamine.
Pharmaceutical substance
Ethylenediamine is a substance that dissolves the active ingredient theophylline in aminophylline, the common sweating bronchodilator drug. Ethylene diamine is also necessary in dermatological preparations, but has been removed from some as it causes contact dermatitis. Using it as a pharmaceutical excipient, its bioavailability is about 0.34, some of the major first-pass effects. With the urinal excretion we expect less than 20% to be eliminated.

ÖZET
Etilen diamin tetra asetik asit (EDTA) etkili bir şelasyon ajanı ve lubrikanttır. EDTA'nın kimyasal olarak kök kanal dentinini yumuşattığı, smear tabakasını kaldırdığı ve dentin geçirgenliğini arttırdığı düşünülmektedir. EDTA dentindeki kalsiyum iyonuna bağlanarak suda çözünebilir kalsiyum şelatları meydana getirir. Smear tabakasının inorganik ve organik komponentlerinin etkin bir şekilde uzaklaştırılması için EDTA ve NaOCl?nin birlikte kullanımı önerilmektedir. Bu makalede EDTA'nın endodontik tedavide kullanım alanı ve etkinliği tartışılmaktadır. Bu derlemenin amacı, endodontide EDTA ile yapılan çalışmaları incelemektir.

Ethylenediamine tetraacetic acid grafted onto chitosan was shown to increase the antibacterial activity of chitosan via magnesium complexation, thereby destabilizing the membrane of Gram negative bacteria (El-Sharif and Hussain, 2011; Valenta et al., 1997). The grafting polymerization of dicyandiamide (DCDA) onto chitosan resulted in the synthesis of a water-soluble derivative that displayed antibacterial activity at pH of 7 and 4 when tested against E. coli and S. aureus (Khalil et al., 2015).

SUMMARY
(EDTA) is an effective chelating agent and lubricant. EDTA is thought to chemically soften the root canal dentin, remove the smear layer and increase dentin permeability. It binds to the calcium ion in EDTA dentin to form water-soluble calcium chelates. It is recommended to use EDTA and NaOCl together in order to effectively remove the inorganic and organic components of the smear layer. This article discusses the use and effectiveness of EDA in endodontic treatment. The purpose of this review is to examine studies with EDA in endodontics
