    Characterization and antimicrobial evaluation of quaternary ammonium compounds synthesized from Canola and coconut oils
    (Federal University of Technology, Owerri, 2021-09) Amaefule, Onyinyechi
    Quaternary ammonium compounds were synthesized from Canola oil (Brassica, napus) and Coconut oil (Cocos nucifera) extracts by reacting the oils with N,N diethylethylenediamine in the presence of potassium tertiary butoxide as catalyst. Fourier Transform Infrared (FTIR) spectrometric analysis of the starting materials, the intermediates and the final products were carried out and the results showed a disappearance of the carbonyl (C=O) stretch of the oil esters at 1744 cm-1and appearance of an N-H band for an amide at 3433 cm-1. Other functional groups such as C=C and C-H stretch of an aromatic compound and C=O stretch of an amide were also observed. Antimicrobial activity of the synthesized quaternary ammonium compounds showed excellent anti-bacterial activity with an inhibition diameter of 22 mm and 28 mm for E.coli by QAC from Cocos nucifera and Brassica napus oils respectively as compared to a standard antibiotic (Ampicillin).
