Title: Process for the preparation of aryl fluorides
IPC: C07B39/00
Filed: 1963-12-06
Abstract: A process for the preparation of aryl fluorides comprises reacting in the gaseous phase at a temperature of 250-600 DEG  C. and aromatic halide with nitrosyl fluoride or a nitrosyl fluoride-hydrogen fluoride complex, using cobaltous fluoride as catalyst, the aromatic halide having at least one aromatically-bound chlorine or bromine atom and at least one aromatically-bound hydrogen atom on each ring and being free from basic substituents, i.e. those which when present make the molecule behave as a base.  The aromatic halide may be a chloro-or bromo-benzene having no substituents other than chlorine or bromine atoms or may have as nuclear substituents one or more cycloalkyl, lower alkyl, fluoro, carboxyl, hydroxyl, nitro or sulpho groups.  The process may be carried out, by continuously passing metered quantities of aromatic halide starting material and fluorinating agent through a suitable reactor, packed with catalyst and mounted in an electrically-heated furnace and connected to a product recovery system.  The reactor and other equipment may be made of nickel, or other material corrosive-resistant to reactants and products formed.  For good rate of reaction and minimization of carbonization and side reactions, temperatures in the range from 300 DEG  to 450 DEG  C. are preferred.  While sub- or super-atmospheric pressures may be employed, the invention can be carried out satisfactorily at substantially atmospheric pressure. In an example, a "Monel" (Registered Trade Mark) tube is charged with cobaltous fluoride pellets as catalyst and 1,2,4 - trichlorobenzene and NOFxHF complex (actually a mixture of NOF3HF and NOF6HF) both in gaseous form were introduced concurrently into the reactor maintained at 406-430 DEG  C.  The crude product recovered as a lower oil phase in a water scrubber immediately downstream from the reactor was water-washed, dried, and distilled, from which 1,2,4-trifluorobenzene was separated as one fraction.  Other examples are given of the preparation of 1,4-difluorobenzene and 1,2,4-trifluorobenzene.  A list of starting materials is also given. Specification 941,537 is referred to.

Title: Implantable blood vessel prosthesis
IPC: A61F2/06
Filed: 1977-11-29
Abstract: A method and article for performing an aneurysm repair is the subject of the present invention. A prosthetic graft is utilized to replace the damaged segment of the blood vessel. The graft is characterized by being movable from a collapsed formation of a diameter less than the diameter of the vessel to an open formation of a diameter approximately equal to that of the vessel. A plurality of radially spaced anchoring pins are located adjacent each end of the graft and provide means for securing the graft to the wall of the healthy vessel, on opposite sides of the aneurysm. Once in place, hemodynamic pressure will assure a continued fluid tight seal between the graft and the healthy vessel wall tissue. The prosthetic graft may be used without the need for major surgery by securing it to a catheter and inserting the catheter at a distal location from the aneurysm. The catheter with the prosthetic graft attached is moved through the vessel, utilizing fluoroscopic and X-ray data, to the area of the aneurysm. When in the proper location, the graft is moved, through remote control, to the open formation where the anchoring pins secure it to the vessel wall. The catheter may then be withdrawn as is the remote control operative linkage.
