A new compound represented by the formula ##STR1## WHEREIN X represents hydrogen atom, chlorine atom, bromine atom, methyl group or nitro group, Y represents hydrogen atom, methyl group, an alkylcarbonyl group where the alkyl group has from 1 to 12 carbon atoms and may be substituted by one or more halogen atoms, a lower alkoxy carbonyl group, a lower alkylamino carbonyl group or a metal atom of which the valence is 1 or 2, Z represents hydrogen atom or chlorine atom and n represents 2 when Y represents a metal atom of which valence is 2 and n represents 1 when Y represents said group or said atom except a metal atom of which valence is 2 but when X and Z represent hydrogen atom, Y does not represent hydrogen atom or a metal atom is employed to control the growth of bacteria, fungi and algae which propagate on industrial raw materials and products or in water in circulating water systems.
A compound represented by the formula ##STR12## wherein X represents hydrogen atom, chlorine atom, bromine atom, methyl group or nitro group, Y represents hydrogen atom, methyl group, an alkylcarbonyl group where the alkyl group has from 1 to 12 carbon atoms and may be substituted by one or more halogen atoms, a lower alkoxy carbonyl group, a lower alkylamino carbonyl group or a metal atom of which valence is 1 or 2, Z represents hydrogen atom or chlorine atom and n represents 2 when Y represents a metal atom of which valence is 2 and n represents 1 when Y does not represent a metal atom of which valence is 2, but when X and Z represent hydrogen atom, Y does not represent hydrogen atom or a metal atom.
A method for killing bacteria, fungi and algae comprising applying to industrial raw materials, industrial products and water in circular water systems an effective amount of one or more compounds of the formula ##STR13## wherein X represents hydrogen atom, chlorine atom, bromine atom, methyl group or nitro group, Y represents hydrogen atom, methyl group, an alkylcarbonyl group where the alkyl group has from 1 to 12 carbon atoms and may be substituted by one or more halogen atoms, a lower alkoxycarbonyl group, a lower alkylamino carbonyl group or a metal atom of which valence is 1 or 2, Z represents hydrogen atom or chlorine atom and n represents 2 when Y represents a metal atom of which valence is 2 and n represents 1 when Y does not represent a metal atom of which valence is 2, but when X and Z represent hydrogen atom, Y does not represent hydrogen atom or a metal atom.
A bactericidal, fungicidal and algicidal composition comprising 99.5-5% by weight of a suitable adjuvant and 0.5-95% by weight of one or more compounds of general formula ##STR14## wherein X represents hydrogen atom, chlorine atom, bromine atom, methyl group or nitro group, Y represents hydrogen atom, methyl group, an alkylcarbonyl group where the alkyl group has from 1 to 12 carbon atoms and may be substituted by one or more halogen atoms, a lower alkoxy carbonyl group, a lower alkylamino carbonyl group or a metal atom of which valence is 1 or 2, Z represents hydrogen atom or chlorine atom and n represents 2 when Y represents a metal atom of which valence is 2 and n represents 1 when Y does not represent a metal atom of which valence is 2, but when X and Z represent hydrogen atom, Y does not represent hydrogen atom or a metal atom.
