A fiber reaction process whereby reactive components contained in immiscible streams are brought into contact to effect chemical reactions and separations. The conduit reactor utilized contains wettable fibers onto which one stream is substantially constrained and a second stream is flowed over to continuously create a new interface there between to efficiently bring about contact of the reactive species and thus promote reactions thereof or extractions thereby. Co-solvents and phase transfer catalysts may be employed to facilitate the process.

An apparatus includes a conduit with two process fluid inlets at one end of the conduit, one process fluid outlet at an opposing end, a heat exchange medium inlet, and a heat exchange medium outlet. One of the fluid inlets includes a tube extending into the conduit and a perforated node at the end of the tube, and the other of the fluid inlets is arranged up stream of the perforated node. The apparatus further includes hollow tubes positioned longitudinally within the conduit between the two process fluid inlets, the process fluid outlet, the heat exchange medium inlet and the heat exchange medium outlet. In addition, the apparatus includes a collection vessel positioned proximate the fluid outlet and fibers extending through each of the hollow tubes, wherein one end of the fibers is secured to the perforated node and the other end of the fibers extends into the collection vessel.
