Abstract
Biocidal compositions and methods of inhibiting biological growth employ, as the active agent, certain monocyclic and bicyclic heterocyclic compounds, some novel perse, of general formula I ##STR1## in which X is 0,1 or 2, R.sup.1, R.sup.2, R.sup.5 and R.sup.6 are a hydrogen atom, an alkyl radical containing up to 20 carbon atoms or an aryl radical; R.sup.3 is a hydrogen atom or a lower alkyl radical containing up to 6 carbon atoms; and R.sup.7 and R.sup.8, when taken separately, are hydrogen atoms or, when taken together, are ##STR2## in which R.sup.4 is a hydrogen atom, an alkyl radical containing up to 16 carbon atoms or an aryl radical. The preferred active agents generally have low solubility in sea water, are toxic to algal, barnacle or fungal growth, and are colorless. They may be used to form anti-fouling paints free from undesirable heavy metals or as anti-fungal additives in hydrocarbon fuels.
