Aromatic hydrocarbons are dealkylated by contact with hydrogen in an unpacked tubular reactor under temperature, pressure and time conditions such that at least 90% conversion is effected, and the selectivity of conversion to dealkylated product is maintained at at least 90 mol per cent by controlling the coking factor K c  such that it is maintained in the range 2À0-9À0. K c  is defined thus where YH 2  and Y CH4  are, respectively, the hydrogen and methane concentrations in the reactor effluent gas in mole fractions, P t  is the total pressure in the reaction zone in atmospheres gauge, and K e  is the equilibrium constant for the reaction CH 4  # C + 2H 2  at the maximum temperature in the dealkylation zone. Various ways of controlling K c  are indicated, and the process is suitable for producing benzene from toluene, toluene from xylenes, and naphthalene from methyl naphthalene.

Title: Acylated ureas and compositions containing them
IPC: C07C275/50
Filed: 1958-11-04
Abstract: The invention comprises N-(2-ethyl-crotonoyl)-N1-methylurea as both the cis- and the transisomers, and the preparation thereof by dehydrobromination of N-(2-bromo-2-ethylbutyryl)-N1-methylurea in the presence of a dehydrohalogenation agent.  The use of an oxide of a metal, e.g. beryllium, cadmium, calcium, copper, lead, mercury, silver, zinc or zirconium, as such agent leads to the formation of the cis-isomer, while with pyridine as the agent the trans-isomer results.  The latter can also be prepared by reacting N-methylurea with 2-ethyl-2-butenoyl chloride, advantageously by refluxing for from 3 to 5 hours.  Examples are given.  N - (2 - bromo - 2 - ethylbutyryl) - N1 - methyl - urea is prepared from N-methylurea and 2-bromo - 2 - ethylbutyryl chloride.  Specification 864,284 is referred to.ALSO:A therapeutic composition having sedative and hyponotic activity comprises from 2 to 7 grains of N-(2-ethyl-crotonoyl)-N1-methyl-urea and a pharmaceutical carrier in unit dosage form.  Suitable diluents and additives include cellulose powder, cornstarch, lactose, talc, stearic acid, magnesium stearate and gums, and the compositions may take the form of tablets, powders, capsules or suspensions suitable for oral ingestion.

Filed: 1931-12-30
Abstract: <PICT:0372251/III/1> In apparatus for determining the proportion of combustible gas in flue gases &c. described in the parent Specification, the insulating supports for the test wire are arranged in an antechamber, which is separated from the catalytic chamber containing the test-wire by one or several transverse partitions provided with orifices for the passage of the gas, thus preventing condensation of the products of combustion on the supports.  In the form shown, the metal block h supporting the holder for the test wire e and from which the leads f, g are insulated, is separated from the main measuring chamber m by a transverse partition k.  A slot n is provided in this partition through which the test wire and its holder can be passed as a unit.  The bottom edge o of the slot is preferably oblique so as to direct the gas stream on to the upper surface of the chamber m before reaching the wire e, thus minimizing the effects of variations in the velocity of the gas stream upon the measurement. The measuring chamber may be lined with a corrosion-resisting material such as lead, and the transverse partition may be made of this material or of an insulating and corrosion-resisting material such as an artificial resin composition.
