摘要:
An alkane is reacted with oxygen and available chlorine in the presence of a solid solution catalyst containing iron cations to yield unsaturated hydrocarbons and chlorinated saturated and unsaturated hydrocarbons. In a preferred embodiment of the process, ethane is reacted with oxygen and available chlorine in the presence of a solid solution catalyst containing iron cations to yield vinyl chloride, ethylene, and other valuable by-products. The conversion of ethane to products approaches 100 percent, vinyl chloride is prepared in up to 40 mole percent yield, and the combined yield of vinyl chloride, ethylene dichloride, ethyl chloride, and ethylene is up to 90 mole percent.

摘要:
Method for producing metallic particles. The method converts metallic nanoparticles into larger, spherical metallic particles. An aerosol of solid metallic nanoparticles and a non-oxidizing plasma having a portion sufficiently hot to melt the nanoparticles are generated. The aerosol is directed into the plasma where the metallic nanoparticles melt, collide, join, and spheroidize. The molten spherical metallic particles are directed away from the plasma and enter the afterglow where they cool and solidify.
摘要:
A pigmented vinyl chloride composition is provided which has a whitening and opacifying package comprising titanium dioxide and a titanium dioxide replacement/extender. The replacement/extender replaces up to 30 percent by weight of the titanium dioxide and yet maintains one or more selected optical property as if the whitening and opacifying package were pure titanium dioxide. These optical properties include the Yellowness Index, the DE* value and the percentage light transmittance. The extender is one or more of an alkaline earth metal titanate, lanthanide titanate, or aluminum titanate.
