Title: Improvements in or relating to the production of phenol
Filed: 1950-10-09
Abstract: Phenol and acetaldehyde are prepared by decomposing the alpha-hydroperoxide of ethylbenzene with an electrophilic catalyst with the exception of sulphur dioxide and aqueous sulphurous acid. The reaction may be carried out in an inert organic solvent, e.g. ethylbenzene.  Suitable electrophilic catalysts mentioned are sulphuric acid of 10 to 95 per cent strength, hydrofluoric acid, hydrochloric acid, boron fluoride which may be in the form of its etherate, acid activated clays of the bentonite type, e.g. an acid active clay referred to as "Clarit Hochactiv," p-toluenesulphonic acid, the complex compounds H2SiF6, HBF4 and BF3.H3PO4 and the complex compound formed by mixing phosphoric acid and boric acid and heating the mixture to about 350 DEG  C.  It is preferable to remove the acetaldehyde from the reaction mixture substantially as soon as it is formed.  The hydroperoxide may be employed in the form of a crude mixture as obtained by the oxidation of ethylbenzene.  A number of examples are given.  Specification 673,576 is referred to.

Abstract: 1,148,673. Fuel cells. VARTA A.G. 6 June, 1966 [12 June, 1965; 28 April, 1966], No. 25162/66. Heading H1B. In a fuel cell, reaction water evolved during operation is removed and the concentration of the electrolyte is maintained substantially constant by automatically discharging diluted electrolyte from the fuel cell or from a tank fed by excess electrolyte from the fuel cell after the evolution of a predetermined quantity of water in the reaction and restoring the concentration of the residual electrolyte. In Fig. 1, electrolyte overflowing from a fuel cell flows into a tank 8. When the level of a float 9 carrying a permanent magnet 10 reaches that of a contact 11 electrolytic fluid is discharged from the tank until the float reaches the level of a magnetic contact 12 when the discharge is stopped and a device 15 for dispensing electrolyte concentrate into the fuel cell is opened. Simultaneously a device 16 for scavenging the gas space in the fuel cell is operated. In Fig. 2, excess electrolyte from a fuel cell 21 is pumped into a distributer 23 feeding a mixing tank 24. Some of the electrolyte from the distributer 23 runs over a movable or pivoted arm 23 into a storage tank 26 until the latter is filled to a given level. The storage tank contains solid alkali metal hydroxide 35. When the density of electrolyte in the mixing tank 24 drops to a predetermined value a float 29 sinks to the bottom and by the operation of a magnetic switch dilute electrolyte is removed from the mixing tank whilst electrolyte of high concentration flows from the storage tank 26 into the mixing tank 24. The electrolytic liquid is pumped from the mixing tank 24 back to the fuel cell battery 21.
