摘要:
The present invention relates to specific water and solvent-free nitrile rubbers having specific functional groups and/or end groups, a process for the production thereof and the use thereof. This process involves removing volatile compounds from a fluid (F) containing (1) at least one nitrile rubber and (2) at least one volatile compound, wherein the process comprises at least the steps of a.) treating the fluid (F) in at least one conversation unit, b.) retreating the concentrated fluid from step a.) in at least one retreating unit and c.) feeding the retreated concentrated fluid from step b.) into at least one retreating unit.

摘要:
Multi phase extractor, comprising an extraction chamber, a washing chamber and a re-extraction chamber, said chambers each having inlets adapted to disperse and discharge a phase therein, and connecting channels adapted to convey a continuous phase from said extraction chamber to said washing chamber, from said washing chamber to said re-extraction chamber from said re-extraction chamber to said extraction chamber, and each of said chambers having drains for removing the phase discharged into it by said inlets.
摘要:
Triphase extraction tower having two chambers connected at their top and bottom parts of overflows, and having ports for feeding and removing a first and second disperse phase.
摘要:
A method for separating electrolyte-containing water from an organic phase by means of permeation on a hydrophobic separating means. The permeated organic solution is substantially depleted in water and the retained water is enriched with electrolytes.

The present invention relates to a process for preparing phosphoric acid esters, in particular monomeric bisaryl diphosphates, or bridged phosphates.
摘要:
The invention relates to an industrial process for purifying the product mixture of a transesterification reaction with a polar, electrolyte-containing organic phase, in which the electrolytes are removed from the permeating polar organic phase by means of a nanofiltration step.
