Patent GB-762421-A (GB)
Title: Process for the production of ketones
IPC: C07C45/65
Filed: 1954-07-06
Abstract: The invention comprises a process for the production of an aliphatic ketone by the reduction of an aliphatic 1,3-keto-alcohol containing from 4 to 6 carbon atoms with hydrogen at a partial pressure in the range 1-100 atmospheres and at a temperature in the range 100-200 DEG C. in the presence of a catalyst having a dehydrating and a hydrogenating effect.  In a modification adapted as a continuous process the catalyst is suspended in the ketone and hydrogen is passed through the suspension.  The reaction apparatus used to carry out the Fischer-Tropsch synthesis may, for example, be used in this modification, in which it is advantageous to use an excess of hydrogen which, after separation of the water and ketone vapours evolved in the reaction from it, can be recycled.  It is also advantageous to add a quantity of the keto-alcohol which is substantially equivalent to the ketone and water which distills off from the suspension, continuously to the suspension.  The catalyst advantageously consists of mixed metal oxides such as copper oxide-chromium oxide or zinc oxide-chromium oxide or of dehydrating and hydrogenation catalysts, such as, on the one hand, aluminium oxide, silica gel, or pumice and, on the other hand, nickel catalysts.  The catalyst may be used as a stationary or fixed bed, e.g. it may be disposed in the tubes of a pipe or tube reactor or the reactor may be lined with catalytic materials. In examples: (1) methyl ethyl ketone is prepared from 3-keto butanol-1 in the presence of copper-chromite at 150-160 DEG  C., the pressure being 40 atmospheres guage at the beginning of the reaction and 18.7 atmospheres gauge at the end; (2) methyl-isopropyl ketone is prepared from 2-methyl-3-keto-butanol-1 under similar conditions.

Abstract: 1512996 Fluid-pressure servomotor systems SUNDSTRAND CORP 12 May 1975 [20 May 1974] 19826/75 Heading G3P Two or more variable displacement hydraulic pumps include servo means for reducing the pump displacements in response to the sum of the output pressures. As shown, a common engine, e.g. of a crawler tractor, drives via gearing 11, 15, 16 the cylinder blocks of a pair of pumps 20, 21 having respective swash-plates 27, 28. The adjustment mechanisms of the latter are identical and comprise, with regard to plate 27, a spring 51 urging the plate to a maximum displacement position and a servo-cylinder 55 acting to reduce the displacement under the control of valve 70. The latter comprises a spool 77 urged rightwards by spring 95 to a position in which land 81 blocks communication between port 74 subject to the pressure in pump output line 33, and port 75 connected to servocylinder 55 via line 79. Spool 77 is urged leftwards by a pin (94), Fig. 2 (not shown) acted upon by a stepped piston (86) responsive to the sum of the output pressures of pumps 20, 21 communicated respectively through lines 84, 91. Thus when the pressure sum exceeds a predetermined value spool 77 moves leftwards to cause fluid to be supplied to servo-cylinder 55 to adjust swash-plate 27 to reduce displacement of pump 20. A feedback mechanism restores spool 77 to its neutral position and comprises a link 102 which transmits movement of swash-plate arm 54 to a cam 100 rotatable on pin 101. Cam 100 acts via piston follower 97 and spring 95 on spool 77. Pin 101 is eccentrically mounted and can be rotated to adjust the loading of spring 95. Reference has been directed by the Comptroller to Specification 1330405.
