Inventor: BETTS MAX WILLIAM
IPC: B01D11/04
Filed: 1964-07-20
Abstract: Hop bitter substance to be analyzed may be extracted from beer, e.g. stout, or wort, by feeding with an immissible solvent, e.g. i-octane, in synchronized pulses through a coiled tube with the axis of the coil horizontally disposed.  Emulsification may be prevented by the addition of oleic or lauric acid, as such or as a reaction mixture e.g. of an alkali metal laurate and phosphoric acid, and extraction may be performed at a pH not greater than 2.5.  The extracted solution may be washed with aqueous sulphuric or phosphoric acid, also at a pH not greater than 2.5.ALSO:In liquid-liquid extraction, the liquids are separately fed in synchronised pulses through a coiled tube with the axis of the tube horizontally disposed and the phases subsequently separated. The process is described in relation to the extraction of hop bitter substances from beers (see Division C6) in an apparatus (Fig. 1, not shown) in which the beer is continuously passed through a filter 2 from which a portion is taken off by a pulse pump 5 and has an additive supplied from a side tube 15.  The solvent is passed by means of a synchronously operated pulse pump 9 to a T-junction where the liquids meet and are passed to the helical coil 7.  After contacting the liquids pass to settling vessel 12 for separate withdrawal through pipes 13 and 14.

Title: Improvements in the manufacture and production of valuable liquid hydrocarbons from solid carbonaceous initial materials or tars, mineral oils and the like by destructive hydrogenation
IPC: C10G1/08
Filed: 1931-11-02
Abstract: <PICT:0381367/III/1> In the destructive hydrogenation of distillable carbonaceous materials with the aid of catalysts dispersed therein, the catalysts are added at least in part after the materials have been heated up to 90 per cent of the reaction temperature.  The catalyst may be added partly during the preheating and further portions may be added at different positions in the reaction chamber. Pit coal impregnated with an aqueous solution of tin oxalate and made into a paste with oil is passed under 200 atmospheres pressure into a preheating coil B heated so that the materials pass into a reaction chamber D at 450 DEG  C.  A catalyst of finely ground molybdic acid and zinc oxide dispersed in oil is introduced into the preheater through a tube C while further amounts of catalyst are fed to the reaction chamber through pipes E, F.  The reaction products are separated in a vessel G, the vapours and gases passing through a heat exchanger H where they give up heat to the hydrogen, the vapours being condensed in a cooler J while the hydrogen is stripped and purified in vessels K, L and then returned to the reaction with fresh hydrogen through a pipe M.  The oily residues are withdrawn through a pipe N, mixed with a middle oil having an aniline point higher than 5 DEG  C., and the solids separated by centrifuging or filtration. Other examples describe the use of iodine, bromine, stannous bromide, and molybdic acid as catalysts.  If several reaction vessels are used the catalyst may be introduced into each vessel.  Metals or their compounds of group 2-8 may be used generally as catalysts, if desired precipitated on carriers such as kieselguhr &c. Catalysts easily decomposed at reaction temperature may be introduced through jacketed pipes or in cooled dispersing media.
Patent GB-304804-A (GB)
Abstract: 304,804. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 22, 1927. Naphthazarine dyes.-Dyestuffs are produced by treating naphthazarine with aliphatic amines, preferably in a closed vessel and in the presence of boric acid or condensing agents having a reducing action, e.g. zinc dust or stannous chloride, at a temperature not exceeding 100‹ C., and separating the products from the small quantity of vat dyestuffs which are simultaneously produced, and are less soluble, by extraction with an organic solvent. In an example, a product which appears to be 2:5: 8-trimonomethylamino-1: 4- naphthoquinone, is obtained by heating napthazarine with aqueous monomethylamine in a closed vessel with zinc dust and recrystallizing the precipitated product, first with monochlorbenzene and then with glacial acetic acid. After the recrystallization from monochlorbenzene the dyestuff may also be purified by distilling in vacuo. In a second example, by adding boric acid, less alkylamine is introduced into the naphthazarine molecule, 2: 8-dimonomethylamino-5-hydroxy. 1 :4-naphthoquinone being produced. The latter, by treatment with alcoholic methylamine and zinc dust, gives the 2 : 5 : 8-trimonomethylamino- 1 : 4-naphthoquinone. The products may be used for dyeing and printing cellulose esters and ethers.
