For large scale production of carbon nanotubes and nanofibers chemical vapor deposition (CVD) method is most effective. Acetylene, ethylene, propylene, methane, natural gas (consisting predominantly of propane), carbon monoxide were used as a source of carbon [ 1 -8] (in view of large number of publications on CNT synthesis these references are selected arbitrary). Ethylene and possibly propylene are most convenient carbon sources for mass synthesis of high quality multiwall CNT (MWNT).

A compressed gas used to expel the contents of containers in the form of aerosols. Chlorofluorocarbons were once widely used because of their nonflammability. The strong possibility that they contribute to depletion of the ozone layer of the upper atmosphere has resulted in prohibition of their use for this purpose. Other propellants used are hydrocarbon gases, such as butane and propane, carbon dioxide, and nitrous oxide. The materials dispersed include insecticides, shaving cream, whipping cream,andcosmeticpreparations. See ozone (note).

Sommer and coworkers have achieved selective carbonylation of propane in superacidic media promoted by halogen. When propane-carbon monoxide mixture (CO propane ratio = 3) was passed through HF-SbFg in a Kel-F reactor at — 10°C with the addition of a small amount of sodium bromide (Br"/Sb 0.5mol%), the NMR spectrum indicated the formation of isopropyloxocarbenium ion in 95% yield with a total conversion of 9% of the propane. This remarkable reaction can be rationalized as in equation 50.

Measurements of speed of sound can only show the change in the overall composition. Therefore, to sense and quantify the change in individual components, a commercial device was used to monitor the concentrations of different gaseous components. Based on measuring speed of sound and thermal conductivity, this device measures equivalent concentration of methane, propane, carbon dioxide and nitrogen. 

Blends of polypropylene short fibres and a pulp of poly(4,4 -dioxydiphenyl-2,2-propane carbonate) or 2,2-bis(4-hydroxy-3,5-dibromophenyl)propane-bis(4-hydroxy-phenyl)propane-phosgene copolymer have been used to prepare paper substitutes useful as insulators for high-voltage cables [282]. 

Figures 6.3 to 6.5 show the apparent-shape-factors of carbon dioxide, 1,1,1,2-tetra-fluoroethane (also known by the refrigeration acronym R134a) and water relative to propane. Carbon dioxide was chosen for illustration because of its large quadrupole moment which would lead to an intermolecular potential which is substantially different from that of propane. In this case, the shape factors are nearly independent of volume and weak functions of...

There are two main methods for the manufacture of poly(2,2-bis(4 -phenyl-ene)propane carbonate), namely direct phosgenation and ester interchange.
