Oxygen high-temperature

The occurrence of fluorescence is often related to inappropriate processing conditions in molten-state and solid-state polycondensation (SSP) (presence of oxygen, high temperature, long retention time, etc.), as well as the later drying of chips where prolonged residence times can occur. 

The simple-looking task is solved by a sophisticated molecular mechanism. Hydrogenase is a metalloenzyme, harbouring Ni and Fe atoms. Like most metalloenzymes, hydrogenases are extremely sensitive to inactivation by oxygen, high temperature and other environmental factors. These properties are not favourable for several potential biotechnological applications. 

Compressed asbestos gaskets have been available for over 120 years. They are resistant to high temperatures and are inert to many alkalis, acids, oxygen, high temperature steam, petroleum products, and organics solvents. They are strong and relatively inexpensive. In many plants they have been the universal gasket material.

Thermal Stability. Thermal stabihty is a measure of an oil s ability to resist chemical change due to temperature in the absence of oxygen. High temperatures can cause oil molecules to split and produce sludge and carbonaceous deposits. The term thermal stability is frequently misused in reference to the oxidation resistance of an oil. 

When acetylene, C2H2, bums in oxygen, high temperatures are produced that are used for welding metals.
