Oxygen Atoms

The addition of ethane to nitrogen dioxide either during exposure to radiation transmitted by pyrex, or afterwards, reduces the amount of oxygen formed. At room temperature this is apparently due to the effectiveness of ethane in promoting the reverse reaction of nitric oxide and oxygen to form nitrogen dioxide. At temperatures over 100° there is a reaction which uses oxygen atoms produced in the primary process. Nitroethane (or nitrosoethane) is formed along with carbon monoxide, carbon dioxide, and some methane. The results suggest that acetaldehyde is an intermediate, but acetaldehyde could not be detected because it would react thermally with nitrogen dioxide. It is not possible to give a complete explanation of the results, but suggestions can be made which might form the basis for later work.

In Fire

An important aspect of the flammability question which needs investigation is that of the lethal gases which are emitted when synthetic carpets are burned. Several studies have found that toxic gases and smoke are a major cause of fatalities to individuals involved in fire situations. This study examined gases which were produced when carpets of nylon, acrylic, or acrylic/modacrylic fibers were burned. Infrared spectra of the carpet fibers were obtained upon pyrolysis of the samples. The results showed that hydrogen cyanide, carbon dioxide, carbon monoxide, acrylonitrile, acetylene, ethylene, methane, and ammonia were emitted. Each of the specific toxicants produced upon burning can be lethal if present in sufficient quantities. In addition, research has shown that cumulative and synergestic effects of these gases may cause debilitation and death. This study indicates the possible need for biological smoke tolerance standards for interior furnishings.
