Abstract

The aim of our research was to synthesize and apply chemicals that can control both the electrochemical and microbiological corrosion. In order to achieve this result N-hydroxymethylated aminoacids were synthesized and used as corrosion inhibitors and as biocides. With weight loss tests and linear polarisation experiments were proven their efficiency as corrosion inhibitors. The biocide activity was measured in microbiological experiments. It was important to learn whether these molecules can control the growth both of the planktonic as well as of the biofilm-embedded microbes, too. With different calculations correlation was found between the molecular structure and their efficiency.
