Title: Treatment of gas liquor and other waste liquors for the separation and recovery of phenol therefrom
IPC: C07C37/00
Filed: 1925-12-15
Abstract: 244,774. Heffner L. W. and Tiddy, W. Dec. 16,1924, [Convention date]. Ammonia, distilling.-Gas liquors and other liquors containing phenol in small quantities, such as waste waters from the manufacture of phenolic resins or condensation products, are treated for the separation and reoovsry of phenol by heating them to 98‹ C. or over in a stream of ammonia sufficient to carry away the phenol as ammonium phenolate. The phenol may be recovered by passing the gas through a washer containing lime, caustic soda, absorbent carbon, or other absorbent. In treating gas liquor, the liquor passes from a pipe 22 either directly by a pipe 20 or through a coil in a dephlegmator 28 to a preheater 1 and thence by a pipe 5 to the upper end of a free ammonia still 4, situated over a liming chamber 9. The liquor passes from the liming chamber into a fixed ammonia still 10, the gases from which pass by a pipe 12 into the still 4. The apparatus is operated so that the liquor in the upper end of the still 4 is at 98-103‹ C. The vapours from this still pass directly or through a cooler which reduces the temperature to about 98‹ C. to effect a separation of water, into a phenol absorber 26 and thence through a cooler or dephlegmator 28 and by a pipe 31 to a saturator or condenser. Part of the ammonia may be returned to the base of the still 4 by a pump 37 in. order to obtain a sufficient current of ammonia to carry over the phenol. The condensate, from the dephlegmator 28 is passed into the fixed ammonia still 10.

Abstract: 310,383. Johnson, J. Y., (I. G. Farben industrie Akt.-Ges.). Nov. 25, 1927. Electrodes.-Finely divided iron, nickel &c. for use as the active material of alkaline storage batteries is obtained by heating the corresponding metal carbonyl. Iron carbonyl may be decomposed in the hot free space of a heated vessel as described in Specification 269,677, [Class 72, Iron &c.], the temperature being between 200‹ and 300' C. Nickel carbonyl may be decomposed on smooth surfaces heated from 100‹ to 200‹ C., the nickel film so obtained being then comminuted. The metal powders may be finally heated to 500‹ in a current of hydrogen. The iron powder and the active mass containing the nickel flakes may be shaped for filling the pockets of the electrodes by pressing or heating in moulds. A method of decomposing nickel carbonyl is described consisting in passing the carbonyl vapour through an inclined porcelain tube which is rotated and heated and contains sharp-edged fillers. The wall of the tube becomes coated with a film of nickel which is detached by the movement of the fillers.
