  • Publication number: 20130303783
    Abstract: A continuous process for generation of phosgene from CO and Cl2 and consumption of the phosgene thus generated in a liquid-phase reaction so as to form organic products P. The process is implemented in two successive reactors R1 and R2, the first reactor R1 being a reactor for catalytic synthesis of phosgene from CO and Cl2 gas, and the second reactor R2 being a piston reactor, the second reactor R2 being equipped with a mechanical axial agitation device.

  • Patent number: 6596902
    Abstract: There is provided a process for the preparation of 2-aryl-5-(perfluoroalkyl)pyrrole compounds from N-[1-chloro-1-(perfluoroalkyl)methyl]arylimidoyl chloride compounds. The 2-aryl-5-(perfluoroalkyl)pyrrole compounds are useful for the control of insect and acarid pests, and may also be used to prepare other pesticidal arylpyrrole compounds. In addition, the present invention provides compounds which are useful as intermediates in the preparation of arylpyrrole compounds.
