Patent number: 5880167Abstract: The invention relates to polyurethane compositions with a low content of monomeric diisocyanates. Trifunctional isocyanates optionally reduced in their functionality to 3.0.+-.0.7 with a monofunctional terminator are preferably used for this purpose. In this way, the compositions contain considerably smaller quantities of readily volatile isocyanates. The compositions are suitable for use as reactive hotmelt adhesives, lamination adhesives, adhesive/sealing compounds, primers and for the production of foam plastics from non-reusable pressurized containers (aerosol cans). The low content of volatile monomeric diisocyanates enables the need for safety measures in the workplace to be significantly reduced, in addition to which the disposal of residues remaining in the containers is made considerably easier.Type: GrantFiled: March 27, 1997Date of Patent: March 9, 1999Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Michael Krebs, Gerd Bolte, Christa Dernst-Mentges, Guenter Henke, Wolfgang Klauck, Hermann Kluth, Manfred Schumann

Patent number: 5879556Abstract: A method for the recovery of extractant from the aqueous effluent continuously exiting from a solvent extraction circuit, in which the effluent is contacted with the same water-immiscible diluent being used in the circuit as solvent for the extractant, such that the extractant transfers from the aqueous effluent phase to the diluent phase. The diluent phase, now enriched in extractant, is separated from the aqueous effluent, now depleted in extractant. The separated diluent phase can then be recontacted with effluent or may be combined with the organic phase of the solvent extraction circuit.Type: GrantFiled: January 25, 1995Date of Patent: March 9, 1999Assignee: Henkel CorporationInventor: Hans C.
