Abstract:
1. An apparatus suitable for producing dichlorohydrin(s) from multihydroxylated-aliphatic hydrocarbon compound(s) and/or ester(s) thereof comprising: (1) at least one reactor; (2) at least one separation device comprising at least one liquid-vapor contacting device having a bottom end and a top end for applying a gradually decreasing temperature gradient from the bottom end to the top end to substances within the column; (3) at least one port proximal to the bottom end of the liquid-vapor contacting device of the at least one separation device (2) for introducing stripping agent into the bottom end of the liquid-vapor contacting device, and (4) a means for applying a vacuum to the at least one liquid-vapor contacting device of the at least one separation device (2) for reducing the pressure in the at least one liquid-vapor contacting device below ambient atmospheric pressure: wherein the at least one reactor (1) is connected directly or indirectly to the at least one separation device (2) for conducting a reactor effluent stream from the at least one reactor (1) to the at least one liquid-vapor contacting device of the at least one separation device (2) for distillation and/or fractionation, and the at least one port (3) is connected to at least one source of stripping agent.
