Filed: 1967-05-26
Abstract: 1,215,808. Treatment of gases. GAS COUNCIL. 7 May, 1968 [26 May, 1967], No. 24700/67. Heading C1A. Organic sulphur compounds and/or COS and/or CS 2  are removed from inorganic gases and/or vapours by bringing the gases or vapours and steam, into contact with a catalyst which comprises UO 3  and/or U 3 0 8 , whereby the sulphur impurities are converted to H 2 8. The catalyst may be supported on a carrier such as alumina, silica, kaolin, powdered brick, M 3 O, CaO, SrO, BaO. The catalyst may be made by a method disclosed in Specification 1,154,483 or 1,196,412. Particularly active catalysts are made by applying uranium salts of carboxylic acids to the surface of a carrier and then decomposing said salt at a temperature not greater than 650‹ C. The preferred salt is acetate. The catalyst may be formed in situ, thus uranyl nitrate may be impregnated in the carrier and the process effected at more than 140‹ C. to decompose the nitrate and form the catalyst in situ. The amount of catalyst is preferably between 5-20% wt. of weight of oxide and The process is suitably carried out at a temperature of 420-480‹ C. at a pressure between 1-50 atmospheres, atmospheric pressure being preferred. The H 2 S gas produced may be removed by zinc oxide. The process may be used to remove COS from CO/CO 2  mixtures and to remove sulphur containing impurities from air.

Title: Improvements relating to the esterification of pyridine carboxylic acids
Inventor: ARIES ROBERT SANCIER
Filed: 1956-08-13
Abstract: Esters of pyridine carboxylic acids are prepared by refluxing a pyridine carboxylic acid with an alcohol having 1-3 carbon atoms in the presence of a catalytic mass consisting of, or including the reaction product of the pyridine carboxylic acid, the alcohol and an acid esterification catalyst; and recovering the ester by distillation from the reaction mixture.  The residue may then be employed as the catalyst for further esterifications.  Suitable acid esterification catalysts are sulphuric and benzene sulphonic acids. The catalyst may build up in volume; the amount used in the esterification is kept substantially constant by withdrawing the excess of catalyst; this may be hydrolysed, and the pH of the solutions adjusted to the isoelectric point of the pyridine carboxylic acid, which precipitates and is recovered.

Abstract: 151,002. Elektro-Osmose Akt.-Ges., (Graf Schwerin Ges.). Sept. 11, 1919, [Convention date]. Anti-toxins.- Anti-toxic paraglobuline solution obtained from diphtheria serum is purified or concentrated bv an electric current between diaphragms impermeable to the paraglobuline and in the presence of a weak acid or base, with the radicle of which the water migrates under the action of the current. Mineral acids, monobasic or polybasic aliphatic acids, aromatic acids, ammonia, alkylamines, alkyl ammonium bases, and their substitution products may for this purpose be added so as to bring the liquid to about decinormal strength. Other electrolytes are previously removed by current from electrodes behind amphoteric or other diaphragms. In the subsequent concentration or purification, the diaphragm through which the water passes should be pervious to water and the alkali or acid residues. The electrodes K, A may be placed just behind the diaphragms D', D<2>. Solution to be treated is placed in the middle compartment, above which is a reservoir R provided with a narrow tube FL for liquid and a wide tube NL for air, so that a constant level is maintained in the middle compartment. If concentration is to be effected, the reservoir is filled with solution to be treated; if purification is the object, the reservoir contains a weak solution of acid or alkali, which is conveyed through the colloid by the current. Acid and alkali solutions may be used successively. Specifications 12431/00, 21448/14, [both in Class 41, Electrolysis], and 104,688 are referred to.
