Annotation
In this article the regularities of the urea condensation reaction with glyoxal are considered and studied. It is shown that during the condensation of carbamide with 1,2-dicarbonyl compound in the presence of OEDP as a catalyst the product based on tetrahydroimidazo- [4,5- d ]-imidazoledione-2,5 is synthesized with a yield of 80-85%. The obtained products in pure form and in composition with diethylamine , formaldehyde, carbamide and gossypol resin were tested as corrosion inhibitors. It was established that the compositions are effective corrosion inhibitors and protect steel from corrosion by more than 90%.
