    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: 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.

    摘要: A method of forming an aluminum containing film on a substrate includes providing a precursor having the chemical structure: Al(NR1R2)(NR3R4)(NR5R6); where each of R1, R2, R3, R4, R5 and R6 is independently selected from the group consisting of hydrogen and an alkyl group including at least two carbon atoms. The precursor is utilized to form a film on the substrate including at least one of aluminum oxide, aluminum nitride and aluminum oxy-nitride. Each of the R1–R6 groups can be the same or different and can by straight or branched chain alkyls. An exemplary precursor that has is useful in forming aluminum containing films is tris diethylamino aluminum.
