Title: Improvements in the production of substituted butanols
Filed: 1945-09-17
Abstract: 1-Cyclohexyl-butanol-3 is made by hydrogenating beta - (1, 2, 5, 6 - tetrahydrophenyl) - vinyl methyl ketone in the presence of a nickel catalyst, for example at a temperature of 20 to 100 DEG  C. and under a pressure up to 2,000 lbs. per square inch.  The product may then be esterified or etherified.  The beta-(1, 2, 5, 6-tetrahydrophenyl)- vinyl methyl ketone may be prepared by reacting acrolein with 1, 3-butadiene and condensing the 1, 2, 5, 6-tetrahydrobenzaldehyde so produced with acetone in the presence of a strong base.  In examples: (1) beta - (1, 2, 5, 6 - tetrahydrophenyl) - vinyl methyl ketone is hydrogenated in solution in ethyl alcohol in the presence of Raney nickel; (2) the product of (1) is esterified by means of propionic anhydride to yield 1 - cyclohexyl - 3 - propionoxy - butane; (3) the product of (1) is etherified by dissolving in ether and adding sodium, and then adding dimethyl sulphate to give 1-cyclohexyl-3-methoxy-butane.  Other esters and ethers mentioned are the esters of butyric, acrylic. succinic, phthalic and hexahydrobenzoic acids, and the ethers of ethyl, propyl, butyl, lauryl and benzyl alcohols, phenols, and the polyhydric alcohols such as ethylene glycol, propylene glycol and glycerol.

Abstract: 953,629. Mixing carbonated liquids ; agitating by ultrasonic vibrations. ELECTRONIC ASSISTANCE CORPORATION. June 22, 1962 [July 20, 1691], No. 24140/62. Heading B1C. In a process and apparatus for filling and sealing bottles of carbonated liquid, the bottles 12 are passed to a filling star-wheel 10 on which they are filled, leaving a small air-space at the top. They then pass to a star-wheel 18 where contact is made with the neck of the bottle (see also Fig. 2, not shown) by the shoe 30 of an exciter unit such as the ultrasonic transducer 28. A foam is thus generated which approaches but does not reach the upper end of the bottle. The bottles are then transferred to a capping star-wheel 20 where they pass under a hood 82 having a slot, or a succession of perforations 80, through which is projected a jet of gas (conveniently carbon dioxide), thus displacing any air remaining in the necks of the bottles which are immediately capped. U.S.A. Specification 2,916,266 is referred to.

Differences in the speeds of the two engines causes the cam 27 to rotate and actuate one or other of the switches 38, 39 which causes the solenoid 42 to be energized first and then either solenoid 40 or 43. The solenoids 40, 43 and 42 are mounted on a lever 49 pivoted at 48 and the armatures 45, 46 are connected to a second lever 47 also pivoted at 48 and held in a central position by springs 60, 61 and by a bolt 51 actuated by an armature 52. The lever 49 may be actuated by hand through a pin 56 and in turn actuates the rod 59 connected to the regulating mechanism of one of the engines. When one of the switches 38, 39 is actuated, the solenoid 42 is first energized and the bolt 51 withdrawn whereby the lever 47 may be moved relatively to the lever 49 by one of the solenoids 40, 43 to adjust the output of one of the engines. The cam 27 is connected to an indicating needle, and also is arranged that on excessive out of phase conditions the cam operates mechanism to lift both rollers 28, 29 and render the mechanism ineffective.

Title: Hydrocarbon conversion process
IPC: C07C5/56
Filed: 1956-08-14
Abstract: An iodine-reactive hydrocarbon having at least two carbon atoms and non-aromatic carbon-hydrogen bonds is converted to a different hydrocarbon by adding oxygen to a vaporous mixture of the hydrocarbon and hydrogen iodide, the quantity of total iodine (i.e. iodine as iodine, hydrogen iodide or compounds liberating iodine or hydrogen iodide under reaction conditions) being at least 0.1 mol. per mol. of hydrocarbon and the amount of oxygen added being not more than 1 molecular weight proportion per atomic weight proportion of iodine at or near the region of the point or points of oxygen addition, subjecting the resultant mixture to a temperature of at least 450 DEG C. to form a mixture of the hydrocarbon and iodine which is further subjected to a conversion step at at least 300 DEG  C. to obtain the different hydrocarbon. Preferably the first mixture of hydrocarbon and hydrogen iodide is obtained by a preliminary reaction of the hydrocarbon with iodine at above 300 DEG  C.  The process may be applied to the dehydrogenation of alkanes to alkenes, alkadienes and acetylenes; aralkanes to aralkenes; cycloalkanes to cycloalkenes and cycloalkadienes; cyclization and aromatization of alkanes and alkenes having a chain of at least six non-quaternary carbon atoms; aromatization of hydroaromatic naphthenes and cyclo-olefines; and the isomerization of compounds having an aliphatic chain of 5 or 4 carbon atoms including respectively 1 or 2 quaternary carbon atoms to compounds having non-quaternary carbon, such as the reactions described in Specifications 793,135, 793,214 and 793,215.  A diluent such as carbon dioxide or air may be used, and pressures of 0-75 p.s.i.g. are preferred.  Oxygen may be added at a number of points but these should be kept to a minimum, or it can be added throughout the reaction zone by means of a perforated pipe.  Examples illustrate the conversion of (1) and (3) a mixture of n-butane and butane-1 to butadiene; (2) n-hexane to benzene and C6 unsaturates; (4) n-heptane to toluene.

As shown in Fig. 1, the mill comprises a preliminary grinding chamber F, intermediate grinding chamber A, sifting chamber H3 and final grinding chamber K. The material from the preliminary grinding chamber F passes through holes F<4> into chamber A from which the fines are drawn off by an air current and thrown by vanes H<2> into the sifter H3, the coarse material passing through the holes A<1> into the compartment C provided with slots C<1> and thence by helical blades B<2> to lifter arms B3 and through slots A<4> back to the entrance to the chamber for further grinding. The fine material in the sifter H3 is drawn off through a pipe J having a telescopic end J<1> and the coarse material is passed through slots H4 to helical blades H<7> and is transferred by lifter arms H<6> to slots K<1> and finishing chamber K. The ground material from the chamber K passes out through slots K<3> to a compartment M from which it is discharged to helical blades N in a trunnion N and passes through a screen N<2> to an outlet N<3>. Water may be circulated around jackets R, the water entering by a pipe R<1> and leaving by a pipe R2. The preliminary grinding chamber F may be dispensed with and instead of the helical blades B<2> helical pipes may be used.
