Title: Improvements in the production of organic oxygen compounds
IPC: C07C27/22
Filed: 1951-04-17
Abstract: Organic oxygen compounds are obtained by the continuous interaction of carbon monoxide and hydrogen with olefinic compounds at elevated temperature and superatmospheric pressure in the presence of cobalt, the mixture of carbon monoxide, hydrogen and a vaporous cobalt compound, or the olefinic compound being introduced into the reaction space at various points.  The gaseous or liquid olefine may be introduced, for example, through a tube extending into the reaction vessel, the tube containing a plurality of nozzles.  The nozzles may be arranged on the wall of the inner tube at regular intervals and may, for example, be arranged spirally.  Alternatively, the synthesis gas, i.e. a mixture of carbon monoxide, hydrogen and a gaseous cobalt compound, e.g. cobalt carbonyl or cobalt carbonyl hydride, may be introduced through a tube having a plurality of nozzles into a reaction space through which the olefine is flowing.  The reaction temperature may be within the range 80-200 DEG  C.  The CO : H2 ratio may vary between the limits 2 : 1-1 : 3 or higher. If the formation of aldehydes is desired it is preferable to use a ratio of about 1 : 1.  The preferred pressure is between 100 and 300 atmospheres. Suitable olefinic compounds are ethylene and its homologues, e.g. propylene, n- and isobutene, amylenes, diisobutylenes and cracked gasoline fractions up to higher molecular olefines such as octadecene; olefinic compounds having nuclear hydrocarbon substituents or being of nuclear structure, such as cyclohexene, vinylcyclohexane, styrene, pinene as well as oxygenated olefinic compounds such as allyl alcohol, its esters and ethers, esters of unsaturated carboxylic acids such as methacrylates.  In the examples, carbon monoxide and hydrogen are reacted with (a) isobutylene to give iso-valeraldehyde and (b) ethylene to give propionaldehyde in the presence of a cobalt catalyst, the olefine compound or the mixture of carbon monoxide and hydrogen being introduced into the reaction vessel at a plurality of points.

Title: Improvements in or relating to the manufacture of anthraquinone derivatives
IPC: C09B1/28
Filed: 1937-03-25
Abstract: Aralkylaminoanthraquinones are obtained by reacting a nitro- or amino-anthraquinone, which may carry additional substituents, with an aralkylalcohol at an elevated temperature.  Additional substituents specified are halogen, alkyl, hydroxy, alkoxy, nitro or amino groups. The reaction may be effected in an inert solvent such as nitrobenzene or o-dichlorbenzene, and at temperatures ranging from 100 DEG  C. to the reflux temperature of the mass or approximately 200 DEG  C.  When a nitroanthraquinone is used, the presence of alkali is desirable. Monobenzylation of polyaminoanthraquinones may be effected by using an amount of benzyl alcohol only slightly in excess of the theoretical and preferably in a solvent.  In examples, the following compounds are reacted with benzyl alcohol: (1) 1.8-diaminoanthraquinone to give 1.8-di-(benzylamino)anthraquinone; (2) 1.4.5.8-tetraaminoanthraquinone to give 1.5-di-(benzylamino) - 4.8 - diaminoanthraquinone (fast blue shades on cellulose acetate); (3) 1.8-diaminoanthraquinone - 4.5 - dihydroxyanthraquinone to give 1.8-di(benzylamino)-4.5-di-hydroxyanthraquinone; (4) 1-amino-2-bromo-4 - toluidoanthraquinone to give 1 - benzylamino - 2 - bromo - 4 - toluidoanthraquinone; (5) 1.8 - dimethoxy - 4.5 - diaminoanthraquinone to give 1.8-dimethoxy-4.5-di(benzylamino))- anthraquinone; (6) 1-nitro-2-methylanthraquinone (in presence of sodium carbonate) to give 1-benzylamino-2-methylanthraquinone (fast orange shades on cellulose acetate); (7) 1 - nitroanthraquinone (with sodium carbonate) to give 1-benzylaminoanthraquinone (red shades); (8) 1.8-diamino-4.5-dihydroxyanthraquinone to give 1-benzylamino-8-amino-4.5 - dihydroxyanthraquinone (reddish blue); (9) 1.8 - dihydroxy - 4.5 - dinitroanthraquinone (with sodium carbonate) to give 1.8-dihydroxy - 4 - benzylamino - 5 - nitroanthraquinone.  Also in examples, 1.8 - diamino-4.5 - dihydroxyanthraquinone is reacted with b -phenyl ethyl alcohol to give 1.8-di-(b -phenyl ethylamino) - 4.5 - dihydroxy - anthraquinone.

Title: Device for opening up bunched asbestos fibres
IPC: B02C19/00
Filed: 1964-03-04
Abstract: <PICT:1032322/C1/1> A device for opening up the fibres of crude asbestos, separated from the source rock, comprises a cylindrical housing closed, at least at one end, by a cylindrical cover and a closed rotatable drum eccentrically mounted on an axial shaft, within the housing. The rotation of the drum defines an annular passage of varying width.  A slurry of fibres and liquid is forced into said passage under controlled hydraulic pressure and the fibres are subjected to bending to and fro in constantly varying directions. A baffle plate is mounted on the hub of the drum so as to be concentric with the housing and integral with the drum and form a discharge gap which is narrow in relation to the eccentric annular passage defined by the drum.  The driving shaft of the drum may be arranged to perform short reciprocating strokes.  As shown, the fibre/liquid slurry is introduced at 36 and following the arrows is forced into the narrow gap between the housing 1, and the drum 30. The drum may have a resilient lining 33 of rubber or synthetic resin.  The width of the annular passage may vary, e.g. between 0.5 and 5 mm.  After treatment, the slurry passes through the narrow gaps 35 between the baffle plates 34 and the housing, into the chambers 37 and finally into funnels 39 for discharge or subsequent recycling if dressing is not complete. The optional embodiments comprise the reciprocating mechanism for the shaft and also the trap doors 43 in the cylindrical housing, which may be used when the asbestos fibres to be dressed are not tightly adhered and require shorter and less vigorous treatment. A further optional embodiment is illustrated in Fig. 3 (not shown) in which small circumferential grooves are described both on the housing wall and the resilient lining of the drum; this gives a more vigorous treatment to the fibres.

Title: Method of bleaching cellulose pulp
IPC: D21C9/147
Filed: 1975-03-06
Abstract: 1496537 Bleaching pulp MO OCH DOMSJO AB 6 March 1975 [14 March 1974] 9450/75 Heading D1P Cellulose pulp is bleached with a gas containing molecular oxygen and in the presence of sodium bicarbonate, the partial pressure of the oxygen in the gas being at least 1 bar, the partial pressure of the carbon dioxide formed during bleaching being controlled to be within the range of 0.001 - 3 bars, and the bleaching step being carried at a temperature of 110-170C. The process is applicable to hard wood or soft wood pulps and the carbon dioxide level is controlled to give optimum selectivity in favour of deligrification over depolymerisation. The gas stream and pulp may be caused to move relative to one another e.g. by agitation, during bleaching. The carbon dioxide may be removed externally from the bleaching apparatus e.g. by absorption in an alkaline reacting liquor e.g. one containing sodium carbonate and/or bicarbonate, or by chilling and/or absorption. Alternatively, the carbon dioxide - containing gas may be absorbed into an alkaline cellulose pulp prior to the oxygen bleaching step, and the thus treated pulp subsequently subjected to the bleach step. The pulp may be further pre-treated to remove metal compounds e.g. those of copper, iron, vanadium and cobalt, which promote the degradation of carbohydrates. Metal complexing agents e.g. EDTA, amines. hydroxy amines and/or polyphosphates and manganese II salts may be present during the bleach step.

Title: Chemical reaction chamber
Inventor: ASANUMA HIROSHI
IPC: H01L21/3065
Filed: 1987-01-08
Abstract: PURPOSE:To obtain a chemical reaction device being used for a prolonged term without lowering the capacity of a suction pump and decreasing the maintenance frequency of cleaning, by branching a bypass exhaust path as a path for air in a reaction furnace from an exhaust path between the reaction furnace and a dust trap. CONSTITUTION:Since air is taken into a reaction furnace 3 on initial exhaust after a substrate is mounted, a rotary pump 13 is started, and the inside of the reaction furnace 3 is evacuated. When the inside of the reaction furnace reaches predetermined vacuum pressure, the rotary pump 13 is stopped while an exhaust valve 12 is closed, a gas valve 2 is opened and an inert gas is fed from a gas supply system 1, and the inside of the reaction furnace 3 is returned to the state of atmospheric pressure once. Since air is not flowed into an exhaust path 8 by repeating operation on re-operation after the substrate is exchanged, the generation of a solid product is prevented, thus remarkably improving the operating periods of a mechanical booster pump 6 and a rotary pump 7.
