  • Publication number: 20180179150
    Abstract: The present invention relates to a continuous process for preparing a polyisocyanate, in which a polyamine and phosgene are first converted predominantly to carbamoyl chloride and amine hydrochloride and only in minor proportions to polyisocyanate, and a portion of the carbamoyl chloride- and amine hydrochloride-containing reaction mixture thus obtained is recycled into the reaction with phosgene, wherein polyamine, phosgene and the carbamoyl chloride- and amine hydrochloride-containing reaction mixture are mixed intimately in a mixing unit. The portion of the carbamoyl chloride- and amine hydrochloride-containing reaction mixture which is not recycled into the phosgenation is worked up to give the polyisocyanate.

  • Patent number: 9744314
    Abstract: A pharmaceutical aerosol is disclosed which is suitable for delivering an active compound to the mucosa of the nose, the osteomeatal complex or a paranasal sinus. The pressure of the aerosol is not constant, but pulsates at a frequency from about 10 to 90 Hz. The aerosol is further characterised in that it exhibits a low effective flow rate of less than about 5 liters per minute. The aerosol is, inter alia, suitable for the prevention, management, or treatment of a disease, symptom, or condition affecting the nose or the paranasal sinuses, such as acute and chronic sinusitis.
