ACTIVITY OF NEW AMMONIUM IONIC LIQUIDS AGAINST FUNGI CAUSING WOOD MOULDING

The results of the tests of the effectiveness of the action of new, not yet described in the literature group of biocidal ionic liquids were synthesised and presented. Those ionic liquids are derivatives of the leading structure, i.e. didecyldimethyl-ammonium nitrate, and demonstrate strong action against mould fungi. Natural quaternary ammonium salts, mainly extracts from coconut and soybean, and from vegetable fats, were the basis for syntheses. Mycological tests were carried out on the wood of pine Pinus sylvestris L. (sapwood) in accordance with the method as-sumed binding for the assessment of biocide efficacy
