Things that can influence an oxidisation degradation process?

In summary, the conversation discusses the process of degradation via oxidisation and how it may not always be purely oxidising. Other factors, such as hydrophobicity and cleavage reactions, can also influence the process. The person is seeking information or resources on these other factors in order to differentiate between a purely oxidising process and a degradation process involving oxidisation. Additionally, a study on the degradation of p-NP in different gas-saturated solutions is mentioned as an example.

Hopefully I can get away with not describing the mechanics of the process.

In general, if there is degradation of a solution via oxidisation, the process is not always purely oxidising, there can be other factors at work i.e. degradation may cause the solution to become hydrophobic and change the dynamics of the reactions that take place.

I am trying to find a paper, link or person that can describe some other factors (aside from hydrophobicity) that may influence the oxidisation reaction. This is important as I need to try and describe how a purely oxidising process differs from a degradation process involving oxidisation.

I hope the above made some kind of sense, any help would be appreciated.

hmm does the question not make any sense?

Solved. Here is an example of how a degradatory process may also involve cleavage and not just oxidisation:

The degradation of p-NP occurs most rapidly in a solution saturated with a 80%/20% (v/v) Ar/02 mixture and least rapidlyin a solution saturated only with oxygen. This result is reasonable because the initiation of p-NP degradation occurs in two parallel reactions: pyrolytic cleavage of the C-NO2 moiety and attack by 'OH. In a solution saturated with either Ar or O2 alone, only one of the parallel pathways is accelerated

1. What is oxidisation degradation and why does it occur?

Oxidisation degradation is a chemical process in which a substance reacts with oxygen to form new compounds. This can result in the deterioration or breakdown of the original substance. It occurs due to the natural reactivity of oxygen and can be influenced by various factors such as temperature, light, and the presence of catalysts.

2. How does temperature affect oxidisation degradation?

Temperature plays a significant role in the oxidisation degradation process. Higher temperatures can speed up the reaction, causing the substance to degrade more quickly. On the other hand, lower temperatures can slow down the process and prolong the lifespan of the substance. This is because higher temperatures provide more energy for the reaction to occur, while lower temperatures limit the energy available.

3. Can light influence oxidisation degradation?

Yes, light can definitely influence the oxidisation degradation process. Exposure to light can provide the energy needed for the reaction to occur, thus accelerating the process. This is particularly true for substances that are sensitive to certain wavelengths of light, such as UV light. In some cases, light can also act as a catalyst, further increasing the rate of oxidisation degradation.

4. What role do catalysts play in oxidisation degradation?

Catalysts are substances that can speed up a chemical reaction without being consumed in the process. In the case of oxidisation degradation, catalysts can increase the rate of reaction by providing an alternative pathway for the reaction to occur. This means that even small amounts of a catalyst can have a significant impact on the speed of oxidisation degradation.

5. How can the rate of oxidisation degradation be slowed down?

There are several ways to slow down the rate of oxidisation degradation. One method is to limit exposure to oxygen by storing the substance in an airtight container. Another way is to lower the temperature, as mentioned earlier. Additionally, antioxidants can be used to inhibit the oxidisation process by neutralizing free radicals that contribute to degradation. Finally, choosing materials that are less reactive with oxygen can also slow down the process.
