Definition
ChEBI: A member of the class of 1,2-thiazole that is 1,2-thiazol-3-one substituted on the nitrogen (position 2) by an octyl group. A fungicide and antibacterial agent, it is used for treatment of canker and other fungal and bacterial diseases in fruit trees. It i
no longer approved for use within the European Union.
General Description
Clear dark amber liquid. Used as a fungicide.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
2-Octyl-2H-isothiazol-3-one reacts as an isothiocyanate. Isothiocyanates are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat.
Fire Hazard
2-Octyl-2H-isothiazol-3-one is probably combustible.
Flammability and Explosibility
Nonflammable
Contact allergens
This isothiazolinone, contained in relatively few products
compared to other isothiazolinones, is used in
cleaning and polishing agents, latex paints, stains,
adhesives, wood and leather preservatives, metalworking
fluids (cutting oils), and plastic manufacture.
Safety Profile
Moderately toxic by
ingestion and skin contact. A skin and
severe eye irritant. A rmldewcide. When
heated to decomposition it emits very toxic
fumes of SOx and NOx. See also
KETONES.
Potential Exposure
Isothiazolone/isothiocyanate/heteroaramatic
fungicide and microbiocide used on textiles, in metalworking
fluids, and some water thinned paints. Its use as
a fungicide on cotton was canceled in the United States and
the tolerances were revoked in 1998.
Shipping
UN2922 Corrosive liquids, toxic, n.o.s., Hazard
class: 8; Labels: 8-Corrosive material, 6.1-Poisonous materials.
Incompatibilities
Oxidizers. Contact with hydrogen peroxide
may form explosive material. Isothiocyanates are
incompatible with many classes of compounds, reacting
exothermically to release toxic gases. Reactions with
amines, aldehydes, alcohols, alkali metals, ketones, mercaptans,
strong oxidizers, hydrides, phenols, and peroxides can
cause vigorous releases of heat. Ketones behave a weak
acid. Forms water soluble alkali metal salts. Ketones are
reactive with many acids and bases liberating heat and
flammable gases. The amount of heat may be sufficient to
start a fire in the unreacted portion of the ketone. Ketones
react with reducing agents such as hydrides, alkali metals,
and nitrides to produce flammable hydrogen gas and heat.
Ketones are incompatible with isocyanates, aldehydes, cyanides,
peroxides, and anhydrides. They react violently with
aldehydes, nitric acid, and perchloric acid.
Waste Disposal
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations governing
storage, transportation, treatment, and waste disposal.
Under 40 CFR 261.5 small quantity generators of this
waste may qualify for partial exclusion from hazardous
waste regulations.
Check Digit Verification of cas no
The CAS Registry Mumber 26530-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,5,3 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 26530-20:
(7*2)+(6*6)+(5*5)+(4*3)+(3*0)+(2*2)+(1*0)=91
91 % 10 = 1
So 26530-20-1 is a valid CAS Registry Number.

Paragraph 0032-0034; 0036-0038; 0040-0042; 0048; 0049, (2021/01/11)
The invention discloses a method for coproducing OIT and DCOIT. The method comprises the following steps: adding a raw material N, N'-di-n-octyldithiodipropionamide or N-n-octylmercaptopropionamide and a solvent into a chlorination reaction kettle, introducing chlorine, and carrying out solid-liquid separation on the material in the reaction kettle after the reaction is finished; distilling the obtained mother liquor under reduced pressure, and reserving kettle residues for later use; transferring the obtained filter cake to a neutralization kettle, adding a solvent and alkali liquor for neutralization and liquid separation to obtain an organic layer; carrying out water washing, desolventizing and filtering part on the organic layer to obtain the OIT finished product; carrying out azeotropic dehydration on the other part of the organic layer, combining with the kettle residues, introducing chlorine for chlorination, adding an alkali liquor into reaction liquid obtained after the reaction is finished for neutralization, and filtering; and recrystallizing the obtained filter cake, and leaching and drying the obtained solid to obtain the DCOIT finished product. According to the invention, the production efficiency is improved, the product quality is improved, and the method is an efficient and environment-friendly production method.

Paragraph 0011; 0027-0032, (2019/02/08)
A preparation method of 4,5-dichloro-N-n-octyl isothiazolinone uses N,N- di-n-octyl-3,3-disulfide-di-propionamide as a raw material, and comprises the following steps: mixing N,N- di-n-octyl-3,3-disulfide-di-propionamide with a chloro solvent; adding a composite catalyst comprising metal chlorides, thiophene compounds and crown ether compounds; adding a chlorating agent at a low-temperature condition for closed-loop chlorination; carrying out separation and purification to obtain the 4,5-dichloro-N-n-octyl isothiazolinone. Tests show that the purity of the 4,5-dichloro-N-n-octyl isothiazolinone prepared according to the method can be higher than 98 percent; the product yield can be higher than 65 to 75 percent. Compared with the prior art, the method has the advantages that as the composite catalyst is adopted, the reaction time is short, the product cost is low, and the yield is high; the catalyst, the solvent as well as unreacted raw materials can be recycled, so that the requirements of environmental protection are met; the method is high in selectivity, mild in reaction, easy to control, stable in product quality, and high in yield, thereby being suitable for industrialized production.
