Title: Novel carbazole derivatives,and their preparation
IPC: C07D209/86
Filed: 1964-08-26
Abstract: The invention comprises 9-(3-butenyl)-carbazole and o -tertiary-butoxy-N-n-butyl carbazole. The 9-(3-butenyl)carbazole may be prepared by reacting an alkali metal carbazole with a 1,4-dihalogenobutane to yield the corresponding 9-(4-halogenobutyl)-carbazole which is subjected to dehydrohalogenation to yield 9-(3-butenyl)-carbazole. The dehydrohalogenation is carried out, for example, by treatment with an alkali metal alkoxide, acetate or hydroxide, sodium cyanide, trialkyl amines or pyridine.  If an alkali metal t-butoxide is used the product comprises both 9-(3-butenyl)-carbazole and o -tertiary butoxy-N-n-butylcarbazole.  The reaction with the dihalobutane is preferably carried out at 70-75 DEG  C. or at the reflux temperature of any solvent, e.g. tetrahydrofuran, toluene or benzene, used.  The dehydrohalogenation is preferably carried out at elevated temperature using a solvent, e.g. t-butyl alcohol or diglyme.  The products may be separated by standard methods. In an alternative method for the production of 9-(3-butenyl)-carbazole a 9 - (4 - monohalogenobutyl) - carbazole is converted into the dimethylamine derivative, e.g. by reaction with dimethylamine, which is then oxidized, e.g. by hydrogen peroxide, and subjected to pyrolysis.  The alkali metal carbazole used as starting materia may be prepared by reacting carbazole with an alkali metal hydride in an organic solvent, preferably tetrahydrofuran.

Title: Catalytic cyclisation of pentamethylene diamine
Inventor: SILVERSTONE GERALD ALFRED
Filed: 1953-12-16
Abstract: Piperidine is manufactured by a process comprising contacting pentamethylene diamine in the vapour state at elevated temperature with an acid heterogeneous catalyst of the type used for promoting alkylation of aromatic compounds.  To prevent the formation of by-products an inert gas such as nitrogen or hydrogen may be passed through the reaction zone.  If desired, the piperidine may be converted into pyridine by catalytic dehydrogenation almost simultaneously with the cyclization by mixing a dehydrogenation catalyst such as a platinum or palladium catalyst with the cyclisation catalyst and using hydrogen as the inert gas. Suitable catalysts for the cyclization reaction are, for example, silica gel, alumina-silica beads and boron phosphate.  In the examples: (a) pentamethylene diamine is mixed with nitrogen and passed over (i) silica gel; and (ii) aluminasilica beads to give piperidine; and (b) pentamethylene diamine is mixed with hydrogen and passed over a catalyst consisting of platinum deposited on silica gel to give pyridine.

Abstract: 185,381. Bischof, B., and Haccius, C. Sept. 2, 1921, [Convention date]. Stuffing-boxes, substitutes for; with packing-device acting when apparatus is at rest.-The shaft of a compressor of a refrigerating or other apparatus is packed both when rotating and when at rest. During running one or more collars care pressed against seatings by a spring e acting through a thrust ball bearing i. When the shaft is stationary it is pressed axially by means of a screw f, thus closing one or more valves k on the shaft on to their seatings. The screw f may carry a lever acting as a switch for the electric motor driving the shaft, so that the operations of controlling the motor and moving the shaft axially are performed simultaneously. Alternatively the armature g of the motor may be displaceable axially, so that when the motor is stationary the weight of the armature closes the valve k and when the motor is running the magnetic pull on the armature opens the valve k. The space h may contain packing. Preferably the collar c runs in a liquid contained in a rotating casing s. The liquid forms a centrifugal seal with a stationary disc p. The Specification as open to inspection under Sect. 91 (3) (a) states also that the packing is arranged at the suction side of the apparatus. This subject-matter does not appear in the Specification as accepted.
