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.

 

 

Etilendiamin Uygulamalar
Etilen diamin birçok sanayi kimyasalının üretimi için büyük miktarlarda kullanılır. Karboksilik asitler (yağ asitleri dahil), nitriller, alkoller (yüksek sıcaklıklarda), alkile edici maddeler, karbon disülfid ve aldehitler ve ketonlarla türevler oluşturur. İkili işlevselliği nedeniyle, iki amin bulunduğundan, kolayca imidazolidinler gibi heterosikleleri oluşturmaktadır.

Etilen diaminin en belirgin türevi, siyanür ve formaldehit içeren Strecker sentezi yoluyla etilendiamin'den türetilmiş kenetleme maddesi EDTA'dır. Hidroksietiletilendiamin ticari açıdan önemli bir kenetleme maddesidir. Birçok biyoaktif bileşik ve ilaç, bazı antihistaminikler dahil N-CH2-CH2-N bağını içerir. Etilenebisdithiocarbamate'in tuzları, Maneb, Mancozeb, Zineb ve Metiram markaları altında ticari açıdan önemli fungisitlerdir. Bazı imidazolin içeren fungisidler etilendiamin'den türemiştir.

 

 

Etilendiamin Farmasötik madde
Etilendiamin, ortak tansiyon bronkodilatör ilacı olan aminofilin içerisindeki aktif terkip maddesi teofilini çözündüren bir maddedir. Etilen diamin dermatolojik preparatlarda da kullanılmaktadır, ancak kontakt dermatite neden olduğu için bazılarından uzaklaştırılmıştır. Farmasötik bir eksipiyan olarak kullanıldığında, ağızdan verildikten sonra biyoyararlanımı önemli bir ilk geçiş etkisinden dolayı yaklaşık 0.34'tür. Pisuar atılımı ile% 20'den daha azı elimine edilir.

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).

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.

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.

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
