Abstract
Environmentally-friendly alternatives to organometallic antifoulants that are efficacious at preventing biofouling by organisms such as the zebra mussel. Preferred antifoulant compositions utilize compounds having a Lipophilic-Amide-Spacer-ElectroNegative (“LASEN”) structural motif, such as capsaicin, and compounds having a TetraHydroCannibinoid (“THC”) structural motif. The antifoulant compositions are non-toxic, and effective.
Claims12
An antifoulant composition comprising:
- (a) N-(2-(2-(3,4-dimethoxybenzylidene)hydrazine)-2-oxoethyl)dodecanamide, having the structure:
- (b) anandamide, having the structure:
- (c) N-benzoylmonoethanolamine benzoate, having the structure:
- (d) N-(1-(hydroxymethyl)propyl)decanamide, having the structure:
- or (e) Linoleyl ethanolamide, having the structure:
- wherein the composition is effective at reducing aquatic biofouling on a surface after application to the surface or addition of the composition to the aquatic environment in contact with the surface.
An antifoulant composition comprising:
- a compound having a Tetra-HydroCannibinoid (“THC”) structure,
- wherein the composition is effective at reducing aquatic biofouling on a surface after application to the surface or addition of the composition to the aquatic environment in contact with the surface.
An antifoulant composition comprising:
- (a) O-2050, having the structure:
- (b) CP55,940, having the structure:
- (c) Noladin ether, having the structure:
- or
- (d) AM630, having the structure:
- wherein the composition is effective at reducing aquatic biofouling on a surface after application to the surface or addition of the composition to the aquatic environment in contact with the surface.
A method of treating contained water systems to reduce aquatic biofouling on inner surfaces of the contained water systems comprising:
- contacting an antifoulant compound with the inner surfaces of the contained water system, wherein the antifoulant compound comprises:
- (a) AM630, having the structure:
- (b) anandamide, having the structure:
- (c) N-benzoylmonoethanolamine benzoate, having the structure:
- (d) N-(1(hydroxymethyl)propyl)decanamide, having the structure:
- (e) Linoleyl ethanolamide, having the structure:
- N-(2-(2-(3,4-dimethoxybenzylidene)hydrazine)2-oxoethyl)dodecanamide, having the structure:
- (g) O-2050, having the structure:
- (h) CP55,940, having the structure:
- or
- (i) Noladin ether, having the structure:
