Infrared spectra of CO and CO2 adsorbed on chromia–alumina and on alumina surfaces have been determined. A band near 2200 cm−1 formed by CO on both surfaces at room temperature was due to a weak, non-activated sorption, but also contained a contribution from a more strongly sorbed, activated species on the chromia–alumina. The assignment of this band was discussed in some detail. Bands in the region 1200–1800 cm−1 were considered in terms of surface CO2− species, although in certain instances the appearance of bands at 1750 and 1430 cm−1 may have indicated carbonate ion formation.

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.

Pd Complexes

The previous data obtained by 1H-NMR spectroscopy established the existence of an asymmetry of the bond between Pd and p-allylic groups, even in the p-allyl-Pd complexes dimers which are considered usually symmetric dimers. The asymmetry of the bond depends by the substitutes of the allylic group. Other analytical methods were investigated for additional proof of the obtained results. Thus, this paper discusses how this asymmetry would be reflected in the infrared spectra and in the reaction of the complexes with carbon monoxide.

The paper studies the influence of shielding gas on the composition and the structure of weld joint metal of 30MnB5 steel applied in essential parts of automobiles and tractors. The welding was performed in inert, oxidizing and reducing atmospheres. It was established that TIG welding with argon used as shielding gas did not provide the required mechanical properties when using conventional welding materials. Carbon dioxide during MAG welding caused partial burning of alloying elements. Carbon monoxide used as shielding gas was proved to form reducing atmosphere enabling to obtain chemical composition close to the base metal composition. Metallographic examinations were carried out. The obtained results provided full-strength weld, as well as the required reliability and durability of welded components and joints.
