چکیده

Iron deficiency due to increasing the concentration of bicarbonate, reduces photosynthesis, pigment synthesis, and other metabolic disorders. Therefore the iron deficiency causes the color of young leaves turn to yellow which is called chlorosis. Thus a fast operation applying a synthetic fertilizers is essential to correct this deficiency after the symptoms onset. Iron is not transported within the plant unless using, a continuous iron source. Iron dissolution occurs through chelate in calcareous soils. The usage chelating agent in agricultural fertilizers enhance iron absorption through increasing the concentration gradient of releasable iron. One of important applicable chelates is ethylenediaminedi(o-hydroxy- phenylacetic acid) (EDDHA) [or N,N'-ethylene-bis-2- (o-hydroxy phenyl) glycine (EHPG)]. Synthesizing of this valuable material could be performed by various methods such as cyanidation technique. The aim of this study is synthesized EDDHA by two different methods and compared used methods. In order to achive this purpose, EDDHA was synthesized with the using of two varied carbonyl compounds, phenol and ethylenediamine in alkaline condition. The techniques which are used in this study carried out without cyanidation. Reaction progress was controlled by Thin Layer Chromatography (TLC). Fourier Transform Infrared Spectroscopy (FTIR) and mass spectroscopy (MS) data confirmed the production of the product. Interperation of these analyzing spectra have many new results in this regard.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
