Patent GB-809318-A (GB)
Title: Hydration of propylene
IPC: C07C29/04
Filed: 1957-09-10
Abstract: Isopropyl alcohol and diisopropyl ether are continuously made by passing a mixture of propylene and water, isopropyl alcohol or a mixture thereof at 275-315 DEG  F. and a pressure of 250 to 1500 p.s.i.g. through a bed of a granular catalyst composed of a cross-linked, water-insoluble sulphonated polystyrene resin, and separating the reaction products from unconverted reagents. Preferably the catalyst is a sulphonated resinous copolymer of 80 to 95 per cent by weight of styrene and 20 to 5 per cent of p-divinyl-benzene.  The feed mixture may contain, for example, 0.3 to 15 mols. of water, isopropyl alcohol or a mixture thereof per mol. of propylene.  If the alcohol is the required product water should be used whereas if the ether is desired isopropyl alcohol is used.  If water is used it is desirable that 4 to 10 mols. of water per mol. should be used whereas if isopropyl alcohol is used it is desirable that 0.3 to 5 mols. per mol. of propylene be used plus, optionally, up to 0.5 mols. of water.  Feed rates may range from 0.5 to 10 liquid volumes of total feed per volume of catalyst per hour, the higher rates favouring alcohol production.  The hydrocarbon feed may be essentially pure propylene or C3 fractions containing 30 to 50 mol. per cent of propylene.  In the examples: (a) a hydrocarbon feed consisting of 50 per cent propylene and 5 per cent propane is mixed with water and passed through a bed of granular sulphonated styrene-divinylbenzene resin to give isopropanol with a small amount of di-isopropyl ether; (b) a hydrocarbon feed consisting of 50 per cent propylene and 50 per cent propane is mixed with aqueous isopropyl alcohol and passed through a bed of granulated sulphonated polystyrene catalyst to give diisopropyl ether and some isopropyl alcohol which is recycled.

Title: A process of and apparatus for, washing webs of paper
Filed: 1930-09-24
Abstract: <PICT:0362557/IV/1> <PICT:0362557/IV/2> The washing of paper web is accompanied by friction applied over the whole width of the web and with a reciprocating movement.  The friction is applied by means of a travelling band, or by means of two travelling bands between which the web passes, using apparatus in which the conveyer passes over guide rollers into and out of a bath or series of baths.  In the operation of the apparatus illustrated in the drawings, a web of paper 1 saturated with sulphuric acid of high concentration passes over the driven roller 15 between two bands 19, 23, which are made of woven asbestos, a phosphor-bronze grid, or other material resistant to sulphuric acid.  The web travels between these bands through all the baths 2 .. 6, taking a zig-zag course over and under the rotating rolls 13.  In their passage by these rolls, the bands travel through arcs of different radii, and each band in turn has to travel through a greater distance than the other, so that the web is subjected to a pronounced rubbing treatment, and is thoroughly washed.  The same rubbing effect is produced by the change of direction of the bands as they pass over the driven rollers 14 outside the baths.  The endless bands travel back to the bath 2 over the driven rollers 16, 17, 18 and 22, 21, 20, being freed from fibrous material by jets 24, but one band may continue with the web until it reaches the drying device. The fresh washing water is fed through a conduit 7, and flows through overflow conduits 9, 10, 11, 12, and 8.  Thus washing liquids of different concentrations are used in the baths, so that the amount of water required for washing is kept as low as possible.

The eccentric sleeve is rotated by means of a ring gear 32 engaging a rotatable pinion gear 33 the shaft 34 of which. is journalled in a housing 28 secured to a lateral extension 27 of the bearing member. Dust sealing means comprise a ring 37 secured to the head and a skirt 40 surrounding the upper part of the hub 3. The bearing member, together with the eccentric sleeve, is adjustable by means of a hydraulic mechanism comprising a piston 21. fixed to the frame, slidable within a cylinder fixed to the bearing element. A conduit 22 connects the expansible chamber 20 formed between the piston and the inner end of the cylinder, through a ceversible pump 23, with a fluid reservoir 24. The conduit is also connected through a check valve 25 with a hydraulic accumulator 26. In operation, fluid is pumped into the chamber 20 until the member 14 is raised sufficiently to place the mantle 7 of the head 5 in the desired setting for crushing in connection with the concave 4. Should abnormal crushing conditions occur, fluid in the chamber 20 is forced to enter the accumulator 26 permitting the member 14 to move downwardly in the frame hub 3. When the abnormal conditions are cieared, the excessive pressure in the accumulator forces the member 14 to rise to return the head 5 to its set position.

Title: Improvements in or relating to Isomerization of d-3-Carene to d-4-Carene
IPC: C07C1/00
Filed: 1967-06-21
Abstract: 1,194,710. Cyclic hydrocarbons. HERCULES Inc. 21 June, 1967 [7 July, 1966 (2)], No. 28759/67. Heading C5E. d-4-Carene is produced by isomerizing d-3- carene in the presence of a catalyst system comprising a sodium or potassium base composition having a basicity sufficient to form carbanions of d-3-carene when contacted therewith. The product is an equilibrium mixture of d-3-carene and d-4-carene, and possible byproducts include mixed para- and meta-cymenes and d-isoterpinolene. Suitable catalysts include those prepared from sodium or potassium and a mono- or polynuolear aromatic hydrocarbon, a halogenated aromatic hydrocarbon, a 5- or 6- membered N-heterocyclic compound, an amine or a non-aromatic hydrocarbon; a sodium or potassium alcoholate mixed with a dipolar aprotic solvent; and sodium or potassium supported on alumina. d-Trans-isolimonene (alternatively known as 2,8-p-methadiene) is prepared by heating d-4- carene to effect isomerization thereof, either separated d-4-oarene or a mixture of d-3-carene (which is not isomerized) and d-4-carene being used as starting materials. Possible by-products include mixed para- and meta-cymenes and d-isoterpinolene. d-Trans-2-menthene is prepared by reduction of d-transisolimonene. The following means of achieving this are specified: (a) selective hydrogenation in the presence of a Co, Ni, Pd, or preferably Pt or Ru catalyst; (b) addition of a hydrogen halide to d-trans-isolimonene, followed by removal of halogen from the resulting 8-halo-2-menthene, e.g. by reduction using sodium and alcohol; and (c) converting dtrans-isolimonene to its aluminium derivative, e.g. by heating with triisobutyl aluminium, followed by decomposition with water. d-Isoterpinolene (alternatively known as d- 2,4,(8)-p-menthadiene) may be prepared from d-trans-isolimonene, either by isomerization in the presence of a strong base or by adding HC1 thereto to produce 8-chloro-2-menthene which is then dehydrohalogenated by refluxing with pyridine or alcoholic caustic potash. Possible by-products of the isomerization route include alpha-terpinene and 3,8-p-menthadiene. d-Trans-2-menthene and d-isoterpinolene may be converted to levo-menthol by known means.
