4,5-Dichloro-2-octyl-isothiazolone Chemical Properties,Uses,Production
Chemical Properties
Dichlorooctylisothiazolinone, DCOIT or DCOI, is an isothiazolinone compound. It is a white solid that melts at room temperature. It is an organic chemical that is slightly volatile and can dissolve in water. The measured K values show that DCOIT tends to move from water to octanol and has moderate to high lipophilicity.
Uses
Dichloroctylisothiazolinone is used as a broad spectrum biocide. It is used in paints especially marine coatings, decorative wood coatings and plastic industry. It is used primarily as a dry-film mildew protector for paint, coatings, paper, stains, plastics, wood, shoes, adhesives, metalworking fluids and printing inks. It is easily incorporated into water-based or solvent-based formulations.
Definition
ChEBI: 4,5-dichloro-2-n-octyl-3(2H)-isothiazolone(DCOIT) is a 1,2-thiazole that is 1,2-thiazol-3(2H)-one substituted by chloro groups at positions 4 and 5 and an octyl group at position 2. It is used as a fungicide. It has a role as an environmental contaminant, a xenobiotic and a fungicide. It is an organochlorine compound and a member of 1,2-thiazoles.
Contact allergens
Irritant and sensitizer, Kathon? 930 caused contact dermatitis in employees of a textile fnishing factory.
Safety
The chemical and formulations containing the chemical applied to intact rabbit skin produced severe erythema, oedema and scar formation. The exposed areas had effects that were not reversible. Data indicates corrosive effects in the respiratory tract. While no data are available for effects in the eyes, the chemical is deemed to capable of causing severe damage. There is sufficient evidence to warrant hazard classification.
Synthesis
Add 200 g of ethyl acetate and 23.6 g (0.1 mol) of N,N'-dimethyl-3,3'-dithiodipropionamide into a 500ml four-neck flask equipped with a thermometer and a stirrer, stir and mix, and control The reaction temperature was 15° C., 1.8 g of thionyl chloride (15.1 mmol) was added to the four-neck flask, and the mixture was stirred for 10 min.21.3g (0.3mol) of chlorine gas was introduced into the reaction system, the mixture was stirred for 5h to react, and 27.1g of 4,5-Dichloro-2-octyl-isothiazolone was obtained by filtration and separation. The yield was 84.9%.
