Thermal decomposition, oxides

In an atmosphere of nitric oxide, thermal decomposition produces barium nitrite, Ba(N02)2. Reactions with soluble metal sulfates or sulfuric acid yield barium sulfate. Many insoluble barium salts, such as the carbonate, oxalate and phosphate of the metal, are precipitated by similar double decomposition reactions. Ba(N03)2 is an oxidizer and reacts vigorously with common reducing agents. The solid powder, when mixed with many other metals such as aluminum or zinc in their finely divided form, or combined with alloys such as... 

In marked contrast to the parent ligands, which are unknown in the free state, tetrazadiene complexes are extremely stable. In particular they are much less susceptible to oxidation, thermal decomposition, or hydrolysis... 

To discuss binder burnout in detail, let us consider a spherical green body of radius R with a polymer completely filling its pores undergoing an oxidative thermal decomposition. Figure 15.9 is a schematic of this process. We will use the case where the number of moles of oxygen, n, is 1 that is,...

Although the employment of tetrachloromethane (carbon tetrachloride) in fire extinguishers has now largely been superseded by more efficient and inherently safer materials, this type of extinguisher is undoubtedly still in use, despite the fact that phosgene is a major product of its oxidative thermal decomposition.

COBALT DIBROMIDE (7789-43-7) Br2Co Noncombustible solid. A mild acid. Reacts with acetylene, bases, amines, amides, and inorganic hydroxides strong oxidizers. Thermal decomposition releases highly toxic bromine fumes. Cobalt is a known animal carcinogen. 

A typical chemiluminescence detector consists of a series-coupled thermal decomposition and ozone reaction chambers. The selective detection of nitrosamines is based on their facile low-temperature (275-300°C) catalytic pyrolysis to release nitric oxide. Thermal decomposition in the presence of oxygen at about 1000°C affords a mechanism for conversion of nitrogen-containing compounds to nitric oxide (catalytic oxidation at lower temperatures is also possible). Decomposition in a hydrogen-diffusion flame or thermal oxidation in a ceramic furnace is used to produce sulfur monoxide from sulfur-containing compounds. 

The pharmaceutical industry is one in which quality of the final product cannot be compromised. Any deterioration of the product (e.g., by microbial infection, oxidation, thermal decomposition, contamination by metallic particles or by unremoved organic solvent) must be avoided at any cost. In light of that...

In the majority of cases, polymers in service will encounter both heat and oxygen. It is the norm therefore that these materials will undergo oxidative thermal decomposition and...
