Theimal processing can be accomplished by incineration of the debris at high temperature (>1000°F) or by thermal desorption/decomposition at lower temperatures (<320° to 900°F). High-temperature incineration systems process the waste at high temperature and then pass the combustion off-gas through an afterburner and final off-gas cleaning devices (e.g., filters, carbon absorbers, and/or scrubbers) to ensure as complete as possible destruction and control of contaminants. 

This and other work indicates that HC1 is largely undissociated in nitromethane for [HC1]>- 0.015 M and that there is little association either. There is evidence that a corresponding addition occurs to olefins in theimally degraded PVC. Results carried out in a variety of solvents (26) are consistent with elimination of HC1 occurring by a/3 -elimination of the Ex type favored by polar solvents. The same authors showed that at least in nitrobenzene containing dissolved HC1, the reverse reaction, i.e. addition of HC1, takes place. The fact that this may be interpreted as a retardation of the degradation process may have contributed to the confusion which has arisen and emphasizes the care which must be taken to disentangle the possible catalytic effect of HC1 when concurrent addition of HC1 to the polyenes is possible. 

Thermal Oxidative Stability. ABS undergoes autoxidahon with the polybutadiene component moie sensitive, to theimal oxidation than tire styrene-acrylonitrile component. Antioxidants substantially improve oxidative stability. Studies on the oven aging of molded parts have shown that oxidation is limited to the outer surface (<0.2 mm), i.e., the oxidation process is diffusion limited. 

Theimally allowed [6 + 4] cycloadditions offer the attractive features of high stereoselectivity and rapid increase of molecular complexity. The limiting feature of many higher-order processes, however, is a lack of periselectivity that translates directly into the relatively low chemical yields of the desired cycloadducts. 

The theimally activated conversion of cyclobutenes to 1,3-butadienes is controlled by orbital symmetry. Woodward and Hoffman and Fukui described the allowed thermal process as conrotatory, i.e. one in which the substituents at C-3 and C-4 both move in the same direction, either in a clockwise (equation 8) or counter-clockwise fashion (equation 9). In the photochemical process the motion of the same substituents is in the opposite direction, resulting in the formation of either a trans,trans or a cis,cis 1,3-diene (equations 10 and 11).

There are two main types of NO, formed during combustion fuel NO, and thennal NO,. NO, formed by the oxidation of nitrogen bound in the fuel is called fuel NO,. NO, formed by the fixation of nitrogen in the combustion air at the high temperatures associated with combustion is called theimal NO,. Most of the NO, formed in combustion processes is NO. 

In addition to flaw detection, the added value of AMI is found in its ability to inspect the materials in a non-destructive manner. This allows the possibili of further mechanical, theimal and electrical test to be performed. Because the technology produces an image or map of the sample, it offers immediate feedback to what is happening within the sample. This road map offers invaluable feedback in helping to monitor quali and/or optimize manufacturing processes, parameters and/or materials selection. With the ability to gain information at specific levels, AMI is a powerful non-destructive inspection tool for analyzing the nature of any defect within a sample.
