Preoksügeenimine

Preoksügeenimine refers to the process of introducing oxygen into a substance or system before it undergoes a primary reaction or process. This preparatory step is often employed to modify the material's properties, enhance subsequent reactions, or remove impurities that might interfere with the main operation. In various industrial and scientific contexts, preoksügeenimine can involve controlled oxidation at elevated temperatures or the use of specific oxidizing agents. The exact nature of the preoksügeenimine process and its purpose are highly dependent on the specific application. For example, in materials science, it might be used to create protective oxide layers on metal surfaces or to alter the surface chemistry of polymers. In some chemical processes, preoksügeenimine can help initiate or accelerate the desired reaction by modifying the electronic structure or reactivity of the starting materials. The controlled introduction of oxygen during this phase is crucial, as excessive or insufficient oxygen can lead to undesirable outcomes.
