SYNTHESIS OF THE ETHYLENEDIAMINEDI O-HYDROXY- PHENYLACETIC ACID BY USING DICHLOROACETIC ACID TO APPLY IN AGRICULTURE FERTILIZERS

Iron (Fe), plays a basic role in synthesizing of chlorophyll as an important micronutrient and amount of chlorophyll has a direct intensive effect on photosynthesis. 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. Cyanidation methods needs multi- component and reactions between phenol,, paraformaldehyde, ethylenediamine, cyanide compounds which is dangerous and toxic.The technique which is 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
