Modernization of functioning Fe-HBED chelate manufacturing technology and its implementation

Kamil Ciarka

Abstract

Goal of this dissertation was to develop a modernization of functioning Fe(III)HBED chelate manufacturing technology. The literature part describes role of iron in plants, consequences of its deficiency and methods of supplementation. Chelating agents, including HBED were characterized. Application potential of known synthetic pathways was assessed for HBED and N-(2-hydroxybenzyl)glycine, the intermediate product in modernized technology. In the experimental part the novel method of HBED synthesis was developed. The results of the laboratory research were foundation of European Patent application. Three-step synthetic pathway consisted of obtaining of N-(2-hydroxybenzyl)glycine via condensation and reduction of salicylaldehyde and glycine, its alkylation with 1,2 dichloroethane and iron chelation with isolation of Fe(III)HBED. Optimization of chelating agent synthesis and method of extraction of EDC from reaction mixture was developed. In the technological part of the dissertation, the process design for Fe(III)HBED production technology was presented. Modernization was designed to maximize employment of existing apparatuses on production plant. Description of production method, process flow diagram, mass and energy balances and raw material characteristics were presented. Specification of final product was presented and it meets all requirements, while modernization simplifies production process in terms of technology.
