Title: New process for the manufacture of organic disulphides
IPC: G03D5/06
Filed: 1964-01-13
Abstract: Organic disulphides, particularly dialkyl and diaryl disulphides, are obtained by reacting sulphur with one or more mercaptans in the presence of an aqueous solution of an amine in a quantity sufficient to absorb the hydrogen sulphide which is formed during the reaction. The reaction mixture preferably contains about 2 mols. of mercaptan and about 0.75 atoms of sulphur, while the preferred quantity of amine is at least one equivalent per 2 mols. of mercaptan. The solution of amine hydrosulphide formed is subsequently dissociated in order to regenerate the hydrogen sulphide and the amine, the latter being used again in the sulphidation of the mercaptan. The regenerated H2S is subjected to oxidation in known manner to regenerate sulphur. The preferred amines are those having a boiling point above 100 DEG  C., especially the alkanolamines.  The treatment of the mercaptan with sulphur is preferably carried out at a temperature between 0 DEG  and 50 DEG  C. and may be effected at a pressure higher than atmospheric pressure, e.g. at 1 to 15 atm.  The amine is generally used in aqueous solution with a concentration between 10 and 80%, preferably about 50%.  The process can be carried out continuously or intermittently and the sulphur may be introduced into the reaction mixture as a fine powder in the form of a suspension in the amine solution.  The reaction yields an aqueous phase and an organic phase, this latter comprising the disulphide product.  The aqueous phase, formed by the amine solution containing the combined H2S and a small quantity of dissolved mercaptan is distilled with a view to its dissociation into H2S and amine intended for recycling and for recovery of the mercaptan. Specified disulphides are: dimethyl, diethyl, dipropyl, diisopropyl, di-n-butyl, diisobutyl, dihexyl, dioctyl, dinonyl, didecyl, didodecyl, diphenyl, ditolyl, diethylphenyl, discylyl, ditolylnenzyl, diethylbenzyl and dinaphthyl disulphides.

Filed: 1969-01-10
Abstract: 1,183,697. Cranes. BALDWIN-LIMAHAMILTON CORP. 10 Jan., 1969 [10 Jan., 1968], No. 1632/69. Heading B8B. [Also in Divisions F1 and F2] A boom assembly, Fig. 1, comprises a shipper 11, normally mounted for swinging and elevating movement on a crane supporting vehicle, a boom 12 movable longitudinally within the shipper 11; a first boom extension 13 slidaby mounted in the boom 12 and a second boom extension 14 similarly mounted within the first boom extension 13. A first double-acting hydraulic actuator 21 interconnects the shipper 11 and the boom 12, and second and third double-acting hydraulic actuators 22, 23 respectively interconnect the boom 12 and the first boom extension 13 and the first boom extension 13 and the second boom extension 14. Flow divider valves 41, 42, Fig. 2, are interposed between the actuators 21 to 23 for establishing fixed proportion simultaneous flow rates of hydraulic fluid to and from all the actuators so that all the extendible members of the boom assembly reach their fully extended and fully retracted positions simultaneously. Fig. 4 shows the valve 42 dividing fluid from line 43 between the actuators 22, 23 for extending movement of the boom assembly. Fluid under pressure enters passage 61, passes to the centres of spools 71, 72 through rate determining ports 78, 79 and out through throttling ports 81, 68 and 82, 69 to passages 62, 63 and lines 44, 45. If, for example the flow through passage 63 becomes less than the predeterrnined rate, the pressure drop across the ports 79 drops, increasing the pressure within the spool 72 and moving it to the left which urges spool 71 to the left by compressing spring 77. This partially closes the throttling ports 81, 68 and restores the previous proportion of hydraulic fluid flow in the passages 62, 63. The valve 41, Fig. 3 (not shown), is constructed similarly to the valve 42 and is illustrated showing the positions of the parts of the valve when the boom assembly is being contracted.

Title: Primary aliphatic amines and/or their hydrohalides and process of producing the same
IPC: C07C209/08
Filed: 1956-01-20
Abstract: Primary aliphatic amines are obtained by reacting in the central portion of a vertical reaction zone ammonia and an aliphatic halide which forms a water azeotrope of B.Pt. between the B.Pts. of ammonia and water, charging water to the zone at a point above the central portion, distilling off unreacted ammonia and aliphatic halide from the product in the lower portion of the zone to return these reactants to the central portion, refluxing ammonia in the upper portion of the zone, and recovering an aqueous solution of the amine hydrohalide from the lower portion. When the water azeotrope of the halide distils substantially below the azeotrope of the amine product the latter may be recovered by neutralizing the aqueous solution with a non-volatile alkali such as caustic soda.  In other cases the amine hydrohalide solution must be withdrawn and neutralized in a separate vessel. The process can be operated batch-wise or continuously. Typical operating conditions are 30-40 DEG  C. in the upper part of the zone and 100-200 DEG  C. in the lower, the pressure being from atmospheric up to 300 p.s.i.  Suitable halides for use when alkali is added to the zone are methyl, ethyl and n-butyl chlorides and ethylene and propylene dichlorides, and for external neutralization methyl iodide, ethyl bromide, trimethylene dichloride and cyclopropyl chloride.  The invention is particularly applicable to the production of ethylene diamine from ethylene dichloride, suitable apparatus for this being illustrated.  It is also stated that trifluorethylamine may be obtained from 2 : 2 : 2-trifluoro-1-chlorethane.
