On November 8, 1988, Grove, Scott L. published a patent.Quality Control of 2-Methylisothiazol-3(2H)-one hydrochloride The title of the patent was Wood preservatives containing transition metal carboxylates and isothiazolones. And the patent contained the following:
Wood preservatives comprise a transition metal carboxylate and a isothiazolone I [R1 = C1-18 alkyl, alkenyl, or alkynyl, C≤12 cycloalkyl (C3-6 ring); R2, R3 = H, halo, lower alkyl]. A slurry of dithio-N,N-dimethylpropionamide in ethylene dichloride was treated with SO2Cl2 to give I (R1 = Me, R2 = R3 = H)-HCl and I (R1 = Me, R2 = H, R3 = Cl). A wood preservative composition comprised Cu naphthenate 8, I (R1 = octyl, R2 = R3 = Cl) 2, Atlas G 1096 10, Atlas G 3300 2% and the balance mineral spirits. The experimental process involved the reaction of 2-Methylisothiazol-3(2H)-one hydrochloride(cas: 26172-54-3).Quality Control of 2-Methylisothiazol-3(2H)-one hydrochloride
