  • Device for dispensing a multicomponent flowable substance
    Patent number: 4927059
    Abstract: A device for dispensing a striped mixture of two components of a paste-like flowable substance includes a lower container in which one of the components is retained.

  • Process for the preparation of 5-bromo-5-nitro-1,3-dioxane
    Patent number: 4927946
    Abstract: Unpurified 2-bromo-2-nitro-1,3-propanediol is used as the starting material for a process for the preparation of 5-bromo-5-nitro-1,3-dioxane from 2-nitro-1,3-propanediol without the use of an organic solvent on an industrial scale. This is carried out in such a way that in a first stage a mixture of bromine and aqueous hydrogen bromide solution is cooled and an aqueous solution of an alkali metal or an alkaline-earth metal salt of 2-nitro-1,3-propanediol is added at such a rate that, with cooling, the maximum reaction temperature does not exceed 30.degree. C., and then in a second reaction stage paraformaldehyde and sulfuric acid are added, left to react above room temperature, and the organic phase separated.

  • Process for the formation of shaped agglomerates from particulate solids
    Patent number: 4920090
    Abstract: A new method of forming agglomerates of fine powdered solids comprises dispersing the powder in a chemically inert carrier liquid that also contains a dissolved binder precursor polymer with cyclic dicarboxylic acid anhydride groups on the polymer chain. The dispersion is shaped and then brought into contact with a second carrier liquid that contains polyamines. The polyamines react with the anhydride groups on the other polymer to form an insoluble binder polymer that hardens the shaped dispersion. The hardened shape can then be separated from the liquids and/or further reacted if desired to produce amide bonds in the final agglomerates. The method is useful for forming mechanically and thermally stable agglomerates of such materials as activated carbon, metals dispersed on catalyst carriers, etc.
