  • Method for conducting a chemical process in a packed multi-tubular reactor
    Patent number: 4551325
    Abstract: A method for conducting a chemical process in which a feed containing at least one liquid is introduced into a vessel containing a plurality of packed, vertically arranged tubes, and in which at least one liquid product and at least one gaseous product are obtained, in which the tubes and a space above them are kept flooded with liquid by controlled removal of liquid product from the lower portion of the vessel.

  • Production of ethyl chlorothioformate
    Patent number: 4119659
    Abstract: An improved process for producing alkyl, lower cycloalkyl, lower cycloalkylmethyl, lower alkenyl, phenyl, benzyl, chloro-substituted phenyl and certain haloalkyl chlorothioformates by the reaction of the corresponding mercaptan with phosgene. The process is conducted in two stages, both occurring in a continuous liquid phase, in the presence of an activated carbon catalyst. Production of by-product disulfide is minimized and overall capacity can be increased.

  • Production of ethyl chlorothioformate
    Patent number: 4012405
    Abstract: An improved process for producing ethyl chlorothioformate by the reaction of ethyl mercaptan with phosgene. The process is conducted in two stages, both occurring in a continuous liquid phase, in the presence of an activated carbon catalyst. Production of by-product diethyl disulfide is minimized and overall capacity can be increased.
