A process for converting a chlorinated alkene feedstock including two or more chlorines to reaction products including a less-chlorinated alkene in a commercially substantial proportion, comprising reacting the chlorinated alkene feedstock with hydrogen in the presence of a catalyst consisting essentially of a Group VIII metal other than rhodium, palladium or ruthenium and a Group IB metal on a support.

Processes for converting chlorinated alkenes to useful, less chlorinated

A process for the catalytic conversion of various chlorinated hydrocarbon byproducts and waste products especially to less chlorinated, useful or salable products, in which a chlorinated hydrocarbon feedstock containing two or more chlorines is reacted with hydrogen in the presence of a catalyst consisting essentially of an active hydrogenating metal component such as platinum in elemental or compound form, and a surface segregating metal component such as copper in elemental or compound form on a support.

Processes for converting chlorinated byproducts and waste products to

A hydrodehalogenation process, comprising the step of reacting a saturated halohydrocarbon (e.g., 1,2-dichloropropane) with hydrogen or a hydrogen donor in the gas phase in the presence of a catalytically effective amount of ruthenium on a support, and at temperatures of at least about 100 degrees Celsius, to produce reaction products including a corresponding non-halogenated, unsaturated hydrocarbon (e.g., propylene).

Hydrodehalogenation process and catalyst for use therein

A flow injection analysis flow cell suitable for precipitation titration flow injection analysis wherein the flow cell has a chamber and a dammed space within the chamber. The carrier containing the precipitate is flowed into the dammed space and overflows it into the chamber. The flow cell is designed so that a chemical sensing probe can be inserted into the dammed space to allow precipitation titration flow injection analysis with reduced problems of flow cell plugging.
