Title: The separation of carbon black from gaseous mixtures
IPC: C10K1/04
Filed: 1965-04-20
Abstract: Carbon black is separated from a gas mixture, e.g. one made by pyrolysis or partial combustion of hydrocarbons, by washing the gases with an aqueous emulsion of a water-immiscible hydrocarbon, e.g. one boiling in the range 100 DEG  to 350 DEG  C., e.g. heavy gasoline, kerosene, gas oil, or a tar distillation fraction.  The amount of hydrocarbon may vary between 0.2 parts to 10 parts by weight per part of the carbon black in the gas mixture, and the oil may form 0.1 to 30% by weight of the emulsion.  Where separated carbon black and oil from the emulsion is to be delivered to a burner, part of the oil may be added to the fouled emulsion, enabling the emulsion for washing the gases to be dilute in respect of oil, e.g. where two-stage washing is being practised.  In all cases the separated water is recycled. Emulsifiers may be employed, e.g. up to 1% by weight of the oil. Three specific examples are described.

Filed: 1952-07-04
Abstract: D 7-Androstenes containing in the 3-position an acyloxy or Oxo radical and in the 17-position an acyloxy, Oxo or esterified carboxyl radical are prepared by treating aliphatic sulphonic acid esters of 7 - hydroxy - androstanes containing the required radicals in the 3- and 17-positions with an inorganic or organic base.  The preferred ester reactants are the esters of 3 : 17-diacyloxy - 7 - hydroxy - androstanes, e.g. aliphatic sulphonic acid esters of 3 : 17-diacetoxy-, 3 : 17 - dipropionyloxy- and 3 : 17-dibenzoyloxy - 7 - hydroxy - androstanes and 3 - keto - 7 - hydroxy - aetiocholanic acid esters.  The aliphatic sulphonic acid ester radical may be derived from an alkane sulphonic acid such as methane-, ethane- and propane-sulphonic acid.  Suitable inorganic and organic bases are the hydroxides and carbonates of alkali and alkaline earth metals, pyridine, 2 : 4 : 6-collidine, dimethylaniline and piperidine.  In p the examples, D 7 - 3b  : 17b  - diacetoxy - androstene is prepared from the corresponding 7a -mesyloxy- and 7a  - propanesulphonyloxy - androstanes, D 7 - 3a  - acetoxy - aetiocholenic acid methyl ester is prepared from 3a -acetoxy-7a -mesyloxyaetiocholanic acid methyl ester, D 7-3 : 17-diketo-androstene is prepared from 3 : 17-diketo-7a - mesyloxy - androstane, D 7 - 3b  : 17b  - dibenzoyloxy - androstene is prepared from 3b  : 17b  - dibenzoyloxy - 7a  - ethanesulphonyloxy - androstane, D 7 - 3b  - acetoxy - 17 - keto-androstene is prepared from 3b -acetoxy-7a -mesyloxy - 17 - keto - androstane and D 7-3b  : 17b  - dipropionyloxy - androstene is prepared from 3b  : 17b -dipropionyloxy-7a -mesyloxy-androstane and is hydrolysed with methanolic potassium hydroxide to form D 7-3b  : 17b -dihydroxy-androstene.  Aliphatic sulphonic acid esters of 7-hydroxyandrostanes which are further substituted in the 3-position by an acyloxy or Oxo radical and in the 17-position by an acyloxy, Oxo or esterified carboxyl radical are prepared by oxidizing a D 5-androstene compound with tertiary butyl chromate, the double bond of the resultant D 5-7-keto-androstene is saturated with hydrogen advantageously by means of catalytically activated hydrogen in the presence of an inert organic solvent, e.g. ethyl acetate, the 7-keto-androstane obtained is reduced to the 7-hydroxy-androstane forming the 7a -hydroxy compound as the main product which is then esterified with an aliphatic sulphonic acid.  3b  : 17b  - Diacetoxy - 7a  - mesyloxy - androstane is prepared from D 5-3b  : 17b -diacetoxyandrostene by the above procedure each intermediate compound being isolated.

Abstract: 777,892. Electrodeposition of titanium from fused salt bath. NEW JERSEY ZINC CO. June 14, 1955 [July 6, 1954], No. 17056/55. Class 41. In the cathodic deposition of titanium from a molten salt bath comprising at least one alkali metal or alkaline earth metal halide together with a chloride of titanium having a valency below 4, with simultaneous anodic evolution of chlorine, the anode and cathode are arranged so that without the interposition of a barrier the evolved chlorine rises in the portion A of molten salt between the anode and the adjacent surface of the cathode without entering the portion B of molten salt in contact with the remote surface of the cathode, and are sufficiently close to permit electrolytic depletion of the titanium content of the body A at a rate faster than can be replaced by diffusion from the rest of the molten bath to which titanium tetrachloride is supplied, the diffusion of titanium chloride into the portion A is retarded by restricting the area of the passage joining the two portions of the molten bath, and electrolysis of the titanium chloride is effected at a voltage high enough to maintain depletion of the titanium content of the portion A and to develop a back E.M.F. of at least 2.6 volts but insufficient to effect decomposition of any of the non-titaniferous components of the bath, i.e. not more than 3.4 volts. As shown, the anode 12 may be a rod and the cathode 13 may be a surrounding concentric tube which extends below the level of the anode and may have at its lower end an inwardly projecting flange 16 and is joined at its upper end to a non-corrosive tube 14, e.g. of glass, extending above the level of the bath. Alternatively the anode may be a tube concentrically surrounding the cathode tube which has an annular opening in its lower end. In an arrangement using sets of flat electrodes, the anodes may be arranged between pairs of cathodes, the remote surfaces of cathodes of successive sets being adjacent. Typically for a bath temperature of 560 C., the applied voltage varies between 3.8 and 4.3 volts.
