WIPO Patent Application WO/2006/037274
Kind Code:
A1
Abstract:
An alkoxypropyl isothiazolinone of Formula : C6H6C12N02SR, in which R is CH3, CH2CH3, CH (CH3) 2, CH2CH2CH2CH3, CH2CH2OCH3 or CH2CH2OC6H5Cl. A method for preparing the isothiazolinone by reacting sodium polysulphide with methyl acrylate to obtain dimethyl dithiodipropionate, followed by ammonolysis with alkoxy propylamine to obtain N, N'-dialkoxypropyl dithiodipropionamide, which is then reacted with sulfuric chloride. The alkoxypropyl isothiazolinone of the invention can be used for preparing marine anti-fouling paint coating as antifoulant, and also used as bactericide.
