Apparat und Verfahren zur Erzeugung von einem schwefeltrioxyd-Reagenz für das Sulfonieren der Oberfläche von Polymerenharzen.

摘要

The present invention provides an apparatus and process for generating a reagent solution of sulfur trioxide in a carrier. The apparatus includes a reagent generator which has associated therewith means for introducing sulfur trioxide from a source into the reagent generator, means for introducing a carrier such as a liquid halocarbon or a gas which is nonreactive with the sulfur trioxide into the reagent generator, and means for introducing oleum into the reagent generator. The sulfur trioxide, carrier and oleum are contacted in the reagent generator to provide a reagent solution of sulfur trioxide in the carrier. Additionally, the apparatus includes means for removing oleum from the reagent generator, as well as means for removing the reagent solution from the reagent generator. In a preferred embodiment, the apparatus for generating the reagent solution also includes, in conjunction with the reagent generator, a treatment chamber for the surface treatment of polymeric resinous material including medical products which have polymeric resinous material on exposed surfaces thereof.
