Uses

Since OH-PCB is a toxic byproduct with harmful effects, its uses are not typically sought after. However, it is important to note its presence in the environment and the need for measures to reduce its exposure and production to mitigate its harmful effects. This includes:
Used in Environmental Monitoring:
OH-PCB is monitored in the environment to assess the levels of contamination and the potential risks it poses to ecosystems and human health. This helps in identifying areas with high levels of OH-PCB and implementing measures to reduce its presence.
Used in Research and Development:
OH-PCB is studied in research to understand its mechanisms of action, its effects on various biological systems, and to develop strategies for its mitigation and remediation. This includes developing methods for the detection, removal, and degradation of OH-PCB in the environment.
Used in Regulatory Frameworks:
OH-PCB is considered in the development of regulations and guidelines to control the release and disposal of PCBs and their byproducts, including OH-PCB. This helps in reducing the production and release of OH-PCB into the environment, thereby minimizing its harmful effects.

Method for preparing diclosan through Baeyer-Villiger oxidation

The invention provides a method for preparing diclosan by using urea peroxide as an oxidizing agent. Particularly, the method comprises the following steps: (1) oxidizing 5-chloro-2-(4-chloro-phenoxy)-acetophenone in an inert solvent by using urea peroxide as an oxidizing agent to obtain an intermediate I; and (2) hydrolyzing the intermediate I to obtain the diclosan. The method is safe in production process, mild in reaction and suitable for industrial production.

Preparation method of active bactericide 4,4'-dichloro-2-hydroxyl diphenyl ether

The invention discloses a preparation method of an active bactericide 4,4'-dichloro-2-hydroxyl diphenyl ether. The preparation method comprises the following steps: preparing phenol metal salts from p-chlorophenol under the effect of an alkali solution; carrying out condensation reactions, nitro reduction reactions, and diazotization hydrolysis reactions between phenol metal salts and 2,5-dichloronitrobenzene; extracting the reaction product by a solvent; and purifying the extract by vacuum distillation to obtain the high quality active bactericide. The operation is convenient, the production cost is low, and the product purity is high. The bactericide can effectively kill or inhibit gram positive bacteria and gram negative bacteria. The bactericide can be easily compounded with a negative ion surfactant, a nonionic surfactant, an amphoteric surfactant, and a positive ion surfactant.
