摘要: Processes are disclosed for increasing the condensed phase production of BCl3 comprising less than about 10 ppm phosgene, less than 10 ppm chlorine, and less than 10 ppm HCl. In one embodiment the process comprises injecting an inert gas into a container having condensed BCl3 therein, the condensed BCl3 having therein a minor portion of phosgene impurity. A major portion of the phosgene in the condensed BCl3 is decomposed to carbon monoxide and chlorine by increasing temperature to produce a phosgene deficient stream. The temperature of the phosgene deficient stream is then decreased, and contacted with an adsorbent to remove the chlorine in the stream by adsorption to form a chlorine and phosgene free condensed stream. The chlorine and phosgene free stream is stripped using an inert gas to form a BCl3 product condensed stream, and an inert gas is used to pump the BCl3 product condensed stream to a product receiver.

摘要: A carrier gas for chromatographic analysis of gaseous samples containing sulfur bearing molecules utilizes a sulfur-containing nucleophile mixed with the inert component of the carrier gas to deactivate sulfur reactive and adsorbtive sites in the analysis system and facilitates accurate analysis of the sample composition.

摘要: Herein is disclosed a method and an apparatus for preparing a highly purified gas from a crude liquid comprising the gas and one or more of a metal, particulates, water vapor, or a volatile impurity. The method comprises: (a) vaporizing the crude liquid, to yield (i) a first vapor stream comprising the gas and (ii) a first liquid stream comprising the gas; (b) removing water vapor, particulates, or both from the first vapor stream, to yield a second vapor stream comprising the gas; (c) condensing the second vapor stream, to yield a second liquid stream comprising the gas; and (d) sparging the second liquid stream with an inert gas, to yield (i) a third vapor stream comprising the gas and (ii) a third liquid stream comprising the highly purified gas. Also disclosed is a method for preparing an adsorbent to effectively remove water vapor from the gas, as well as an adsorbent so prepared.
