Abstract (en)

[origin: WO9414731A1] A process for removal of halide from a halide containing organic compound in a solvent, a process for simultaneous removal of halide from a halide containing organic compound and reduction of an oxygen containing organic compound in a solvent, a process for removal of halide from a halide containing organic compound, a process for reduction of an oxygen containing organic compound in a solvent, a system for removal of halide from a halide containing organic compound in a solvent, a system for simultaneous removal of halide from a halide containing organic compound and the reduction of an oxygen containing organic compound in a solvent, and a system for reducing an oxygen containing organic compound in a solvent are disclosed. The process for simultaneous removal of halide from a halide containing organic compound and reduction of an oxygen containing organic compound in a solvent, includes exposing a solvent having a halide containing organic compound and an oxygen containing organic compound, in the presence of hydrogen and a hydrogen halide scavenger, to a catalyst which is capable, in the presence of hydrogen, of (i) converting the halide in the halide containing organic compound to hydrohalic acid; and (ii) reducing the oxygen containing organic compound; at a pressure and at an elevated temperature and for a time sufficient: (a) to convert the halide in the halide containing organic compound to hydrohalic acid; and (b) to reduce the oxygen containing organic compound; and neutralising the hydrohalic acid formed in (a) with hydrogen halide scavenger.
