Oxygen selective addition

These equations give us the means to estimate physical effects by the reduction of oxygen or addition of water on suppression. The equation for flame temperature with a critical value selected as 1300°C gives a basis to establish extinction conditions. 

While a number of oxygen species can exist on the surface of oxides, the reactive oxygen for the selective oxidation of propylene is lattice oxygen. In addition, rapid diffusion of oxygen from the surface into the bulk and from the bulk to the surface often is observed with many selec-... 

Whereas with most alkylating agents the a,y-selectivity is still a problem and one has often to rely on the more pronounced y-selectivity of Cu and Ti derivatives, y-selective addition is, however, normally observed with oxiranes, leading to 1,5-oxygen-substituted systems (46). A 1,4-relationship of oxygen... 

It has to be noted, that aviation gasoline is required to be an all hydrocarbon product. Its components must be chemicals that contain only carbon and hydrogen atoms. The use of oxygenated or other oxygen containing compounds, such as alcohols or ethers, is not allowed. Only a few select additives are permitted and their use is strictly controlled and limited. The primary ingredient in aviation gasoline is isooctane.
