摘要:
A process for removing an impurity from a siloxane comprising i) flowing a first liquid through a fiber bundle comprising a plurality of fibers extending lengthwise in a conduit, wherein the bundle has an upstream end and a downstream end, and the first liquid flows in a direction from the upstream end of the bundle to the downstream end; and ii) while continuing (i), flowing a second liquid comprising a siloxane and an impurity through the fiber bundle in a direction from the upstream end of the bundle to the downstream end of the bundle to effect transfer of at least a portion of the impurity from the second liquid to the first liquid, wherein the first liquid and the second liquid are substantially immiscible.
