异噻唑啉酮主要由5-氯-2-甲基-4-异噻唑啉-3-酮(CMI)和 2-甲基-4-异噻唑啉-3-酮(MI)组成。异噻唑啉酮是通过断开细菌和藻类蛋白质的键而起杀生作用的。异噻唑啉酮与微生物接触后，能迅速地不可逆地抑制其生长，从而导致微生物细胞的死亡，故对常见细菌、真菌、藻类等具有很强的抑制和杀灭作用。杀生效率高，降解性好，具有不产生残留、操作安全、配伍性好、稳定性强、使用成本低等特点。能与氯及大多数阴、阳离子及非离子表面活性剂相混溶。高剂量时，异噻唑啉酮对生物粘泥剥离有显著效果。

异噻唑啉酮是一种广谱、高效、低毒、非氧化性杀生剂。广泛运用于油田、造纸、农药、切削油、皮革、油墨、染料、制革等行业。

行业标准HG/T 3657-2008水处理剂 异噻唑啉酮衍生物

异噻唑啉酮2类产品作粘泥剥离剂时，投加浓度150-300mg/L;作杀菌剂时，每隔3-7天投加一次，投加剂量80~100mg/L。能与氯气等氧化型杀菌剂同时使用，不能用于含硫化物的冷却水系统。异噻唑啉酮季胺盐复合使用效果较佳。

异噻唑啉酮做工业杀菌防霉剂使用时，一般浓度为0.05-0.4%

异噻唑啉酮塑料桶包装，每桶25Kg或根据用户要求确定;贮于室内阴凉处，贮存期十个月。

异噻唑啉酮有腐蚀性、对皮肤和眼睛有刺激性，操作时应配备防护眼镜和胶手套，一旦接触皮肤、眼睛时，应立即用大量清水冲洗。如接触皮肤，立即脱去被污染的衣服和鞋子，用大量清水冲洗至少15分钟，患处涂抹醋酸尿素软膏或烫伤膏，并立即就医。

异噻唑啉酮的合成从基础原料出发，分三步。

1.二硫代二丙酸二甲酯的制备

2.二甲基二硫代二丙酰胺的制备

3.异噻唑啉酮的制备

Isothiazolinones

Isothiazolinones

【CAS】26172-55-4, 2682-20-4 Molecular weight: 115.16

Properties: Isothiazolinones is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) 2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect of Isothiazolinones is carried out through breaking the bond between bacteria algae protein. When contacted with microbes, Isothiazolinones can quickly inhibit their growth, thus leading to death of these microbes. Isothiazolinones has strong inhibition biocidal effects ondinary bacteria, fungi alga, has many advantages such as high biocidal efficiency, good degradation, no residual, safety in operation, good compatibleness, good stabilization, low cost in operation.

Isothiazolinones can mix with chlorine most cation, anion, non-ionic surfactants. When used at high dosage, its biosludge stripping effect is excellent.

Isothiazolinones is a kind of fungicidal with properties of broad spectrum, high efficiency, low toxicity non-oxidative, it is the ideal biocidal in industrial circulating cool water system in wastewater treatment in oilfield, papermaking, pesticide, cutting oil, leather, detergent cosmetics etc..

Specification: Notes: 2%, 4% 8% any concentration can be supplied on demands.

Usage: When used as sludge stripper fgrade II, the dosage of 150-300mg/L is preferred, when used as boicide, the dosage of 80-100mg/L is preferred,ges every 3-7 days. No used together with oxidative fungicidal such as chlorine, no used in cooling water system containing sulfur. When used together with quaternary amine, the effect will be better. When used as industrial fungicide, the dosage of 0.05-0.4% is preferred.

Package Storage: 25kg in plastic barrel, confirmed by clients. Storage ften months in room shady dry place.

Safety Protection: Corrosive, Avoid contact with eye skin, Wear splash resistant safety goggles rubber glores.once contacted, flush with water.
