Title: Improvements in or relating to the production of oxygenated organic compounds
IPC: C07C27/22
Filed: 1950-01-19
Abstract: Oxygenated organic compounds are made by reacting CO and H2 with an olefinically unsaturated organic compound under continuous operating conditions in the presence of a cobalt carbonyl during passage through an elongated reaction-zone, under conditions of elevated temperature and pressure the carbonyl being introduced into the reaction zone, in the gaseous or liquid phase at a plurality of points along the path of the reactants.  The term cobalt carbonyl includes carbonyl hydrides.  Cobalt tetracarbonyl hydride and dicobalt octacarbonyl are preferred carbonyls.  Preferably the total amount of carbonyl added should not exceed 0.6 per cent. (as CO) of the olefinic compound in the feed and the ultimate addition of carbonyl is made before 70 per cent., preferably 60 per cent., of the olefinic has reacted. Generally the initial addition of carbonyl should not cause a temperature rise of above about 30 DEG C.  With very reactive olefines e.g. ethylene, propylene, isobutene, cyclohexene, cyclopentene and straight-chain olefine hydrocarbons of 2-8 C atoms/molecules the initial addition preferably is not above about 0.1 per cent. Carbonyl may be added in a gaseous or liquid solvent and at the several points in such concentration as to give an even rate of reaction through the reaction zone.  More than one reactor may be used and an illustration is provided in which catalyst may be fed to each of three reactors through which the reactants flow consecutively.  In Example 1 this apparatus is used to carbonylate a propylene polymer of B.R. 30-120 DEG C. at 140-150 DEG C. and 3,000 p.s.i. with a water gas feed rate of composition CO/H2 1/1.2 mols. to give a mol. ratio of 3 mols. CO/per mol. of olefine, a CO feed rate of 0.015 per cent. by weight of olefine being maintained to each reactor and a throughput rate of 0.3 litres/litres/hrs the aldehydic product being hydrogenated to alcohols and Example (2) shows the advantage of maintaining low concentrations of catalyst throughout a carbonylation reaction in which propylene is reacted in the presence of xylene such low concentrations being possible when working in accordance with the invention.  The Provisional Specification includes nickel and iron carbonyls.  Specifications 702,191, 702,192, 702,195, 702,196, 702,197, 702,201, 702,204, 702,221 and 702,222 are referred to.

Title: Improvements in or relating to distillation
IPC: B01D3/00
Filed: 1958-01-20
Abstract: A material of wide boiling range is distilled in batchwise manner by a process in which the material is first distilled at constant pressure until the overhead temperature reaches a predetermined value, and distillation is then continued by progressively reducing the pressure while maintaining the overhead temperature within a narrow range; distillation at constant pressure and with rising overhead temperature may then follow. The process may be applied to the distillation of crude petroleum oils to determine boiling-point distribution, and in this case the first stage may be carried out at atmospheric pressure until an overhead temperature of 80 DEG -120 DEG C., preferably 100 DEG C., is reached, whereafter distillation is continued at that temperature while the pressure is progressively reduced to 2 mm. Hg or less; distillation at this low pressure up to an overhead temperature of about 180 DEG C. may then follow.  The initial distillation pressure need not be atmospheric but may be above or below.  The process may be effected in a packed distillation column or a spinning-band column and the temperature and pressure adjustments may be effected by means of a temperature-sensitive device, e.g. a thermistor or a thermocouple, in the column capable of generating or modifying an electric current in response to temperature change.  The Provisional Specification described a modified process in which the material is first distilled by progressively reducing the pressure while maintaining the overhead temperature within a narrow range, and distillation is then continued at constant pressure and increasing overhead temperature.

Abstract: 369,177. Compensating for wear in brakes. FABRICA NACIONAL DE AUTOMOVILES SOC. ANON., 22, Plaza Cataluna, Barcelona, Spain. Jan. 26, 1932, No. 2364. Convention date, Jan. 27, 1931. [Class 103 (i).] In an hydraulically operated brake having shoes 12 contacting with an external drum, wear of the shoes is compensated for by means of a pair of rods 15, which at their outer ends are jointed to the shoes, preferably by means of slots 17 coacting with studs 16 on the shoes to determine the normal clearance between the shoes and drum, and at their inner ends are provided with longer slots 18 through which passes a common spindle 19 fixed to the baseplate 11, the inner ends of the rods being pressed into frictional engagement by a spring 20 surrounding the spindle 19. In operation, when the brake shoes are applied, the studs 16 slide outwardly in the slots 17 and, if undue wear has occurred, they engage the outer edges of the slots and feed the rods 15 forwardly relatively to the spindle 19. On release of the braking force a spring 14 extending between the shoes withdraws the latter, and the studs 16 pass to the inner ends of the slots 17 where they are arrested, since the spring 14 is unable to overcome the frictional resistance between the rods 15. In a modification, the spring 14 is replaced by two springs each disposed between a shoe 12 and the rod 15 associated therewith.
