Abstract
The results of a study of the antifungal properties of an imidazoline hexyl bromide complex obtained on the basis of bicyclo[2.2.1]hept-5-ene-2-carboxylic acid and triethylenetetraamine as an additive to cutting fluids are presented. First, imidazoline was obtained by reacting norbornene carboxylic acid with triethylene tetraamine. In the next step, imidazoline was reacted with hexyl bromide to obtain its alkyl halide complex. The physicochemical properties of the resulting complex were determined, and its composition and structure were confirmed by IR spectroscopy. The complex has been tested as an antimicrobial additive in cutting fluids. It was found that the resulting complex has a destruction zone of 1.3-1.5 cm at a concentration of 0.25% and 2.4-2.6 cm at a concentration of 0.5%. N'-(2,2-bicyclo[2.2.1]hept-5-en-2-yl-4,5-dihydro-1-H- imidazolin-1-ylethyl)ethane-1,2-diamine hexyl bromide complex as an antimicrobial additive exhibiting high fungicidal properties, destroys fungi even at a concentration of 0.25% – the affected area is 1.3-1.5 cm.
