  • Patent number: 6552221
    Abstract: A method of real time process control in a reaction system for the production of acetic acid from the carbonylation of methanol. Reaction system samples are collected from columns and/or transfer lines downstream of a reactor vessel, and the concentration of one or more components in the sample is measured by an infrared analyzer. The concentration measurements are then used to make adjustments in the concentration of components in the reaction system, directly or indirectly, such as by adjusting the temperature profile in a particular column, the flow rate of solution in to or out of a column, the vent gas rate out of the reactor or a column, or the addition or extraction of a component to or from the solution. For optimum process control, the measurements are transmitted to a control unit for real time analysis, and the adjustments are made substantially instantly after the infrared analysis.

  • Patent number: 4629714
    Abstract: An intermetallic compound is disclosed. The compound is formed by reacting a first reaction product, the first reaction product being the product of reaction of a polymeric transition metal oxide alkoxide with a reducing metal having a higher oxidation potential than the transition metal, the polymeric transition metal oxide alkoxide being the product of the controlled partial hydrolysis of a transition metal alkoxide, with a first halide activator to produce a second reaction product. The second reaction product, in turn, is reacted with a second halide activator to form the intermetallic compound. The intermetallic compound is useful as a catalyst component in a catalyst system for the polymerization of alpha-olefins. The catalyst system includes, in addition to the intermetallic compound, a cocatalyst, an organic compound which includes an element selected from the group consisting of aluminum and boron.
