Aimed studies on the synthesis of metal complexonates have carried out. The reaction of obtaining zincate zincate oxyethylene diphosphonic acid OEDP has studied. On the basis of synthesized zincate-OEDP, compositions of corrosion inhibitors and deposits of mineral salts with the addition of a vacuum residue of monoethanolamine (RMEA) and polyaminocrotanol (PKI-3), which are able to effectively suppress corrosion processes in environments with different initial corrosive activity, have been compiled. It is proved that the high efficiency of the composition OEDP : zincate-OEDP : PKI-3 (maximum protective effect - 97.9%) is much more effective than the composition OEDP : zincate-OEDP : RMEA (maximum protective effect - 92.0%). This is due to an increase in ammonium centers, the strength of complexonates based on OEDP, and the presence of a strong methyl-nitrogen bond in the compositions prepared with PKI-3, as a result of which stronger protective layers are formed on the surface of the metal subject to corrosion. Low-stage, energy-saving technologies for the production of inhibitors of mineral salt deposition and corrosion based on local raw materials and secondary industrial products have developed.
