Condensation Products of 2-Propenylphenol, Formaldehyde, and Methylamine and Their Property

A number of compounds with various structures was obtained by the reaction of 2-propenylphenol, formaldehyde, and methylamine. The treatment of the condensation products with HBr resulted in their quaternary ammonium salts. The anticorrosion and biocidal properties and also antimicrobial activity of the obtained compounds and their ammonium salts in relation to S. aureus, E. coli, C. albicans, Sh. flexneri, S. enterica, and A. niger strains were studied. It was found that the ammonium salts have higher bactericidal properties than the standard (amoxicillin). The results obtained were also confirmed by electron microscopy studies.
