2 results about "Methyl-isothiazolinone" patented technology

This utility model relates to the field of 2-methyl-4-isothiazolin-3-one production technology, and particularly to a separation and purification system for 2-methyl-4-isothiazolin-3-one. The system includes a neutralization vessel connected to a feed liquid delivery pipeline and a hydrochloric acid delivery pipeline. The outlet of the neutralization vessel and the extractant delivery pipeline are respectively connected to an extraction tower. The organic phase outlet of the extraction tower is connected to an adsorption device. The outlet of the adsorption device is connected to a distillation kettle. The vent of the distillation kettle is connected to a vacuum condenser. The condensate outlet of the vacuum condenser is connected to a solvent storage tank. The concentrate outlet of the distillation kettle is connected to a crystallization tower. The crystal outlet of the crystallization tower is connected to a centrifuge. The outlet of the centrifuge is connected to a drying device. The outlet of the drying device is connected to a product storage tank. This separation and purification system is rationally designed and can effectively separate impurities from the MIT feed liquid, greatly improving the purity of the MIT product.

This utility model discloses a Kathon production apparatus, relating to the field of Kathon production technology. A 2-methyl-4-isothiazolin-3-one tank is connected to a dissolving tank, which in turn is connected to a phosphate buffer solution tank and a primary microchannel reactor. The primary microchannel reactor is connected to an activating chlorinating agent tank and a secondary microchannel reactor. The secondary microchannel reactor is connected to the activating chlorinating agent tank and a tertiary stabilizer. The inlet of the tertiary stabilizer is connected to a sodium thiosulfate solution tank, and the outlet of the tertiary stabilizer is connected to a Kathon product tank. This significantly improves product yield, shortens the reaction cycle, enhances safety, and is environmentally friendly. The microchannel reactor ensures efficient mass and heat transfer, reduces side reactions, and improves product purity. The tertiary stabilizer ensures complete removal of residual chlorine, improving product stability.
