  • Process for the production of methylene diphenyl diisocyanate isomer mixtures with specific isomer distributions and new products derived
    Patent number: 9090540
    Abstract: The present invention a process and apparatus for the production of methylene diphenyl diisocyanate (MDI) isomer mixtures with a low 2,2?-MDI isomer content and a high 2,4?-MDI isomer content. The resulting mixtures have an increased reactivity and are acceptable in food grade application due to the reduction in primary aromatic amines formed during the curing process. The process and apparatus also include controlling the amount of 4,4?-MDI, which is the most reactive isomer in the mixture allowing use in a wide variety of applications.
    Type: Grant

  • Separation of light gases from halogens
    Patent number: 7883568
    Abstract: A process is provided for separating one or more light gases from bromine or chlorine using one or more physical separations and contact with a chemical scrubber to recover additional halogen. In one aspect, the process comprises (a) providing a feed of halogen containing one or more light gases to a distillation column or flash vaporizer; (b) operating the distillation column or flash vaporizer to separate the feed into (i) a first liquid containing a major amount of halogen and no more than a minor amount of light gas(es), and (ii) a first vapor containing a major amount of light gas(es) and no more than a minor amount of halogen; and (c) providing the vapor to a chemical scrubber to recover halogen from the vapor.
