Patent GB-658700-A (GB)
Title: An improved method of preventing the formation of foams in chemical reactions
IPC: C05B1/10
Filed: 1949-04-21
Abstract: The prevention of foam in chemical reactions between liquids and solids or between two liquids, e.g. the reaction of acids upon phosphates or carbonates in the manufacture of fertilizers, calcium nitrate or phosphoric acid, is effected by introducing the reactants into a compartment 1 (Fig. 1) and forcing <PICT:0658700/III/1> <PICT:0658700/III/2> them, e.g. by a pump 5, into the lower part of a reaction vessel 2 at such a speed that substantially no reaction takes place until they are in the vessel, the reaction then taking place in the lower part of the vessel under the relatively high hydrostatic pressure of the mass contained therein.  The reaction product is withdrawn through an adjustable outlet 7 and a portion of the liquid may be recycled over the weir 3.  In a modification (Fig. 3) the reactants are fed at 19, 20 to a frusto-conical compartment 12 and then forced by a rotary helical pump 15 into the lower portion of reaction vessel 11, reaction product being withdrawn at 16 and a portion of the liquid being recycled over lip 121. One example describes the preparation of phosphoric acid by the action of sulphuric acid on phosphates in the presence of weak phosphoric acid.

Title: Improvements in and relating to rotary regenerative heat exchangers
IPC: F28D19/04
Filed: 1963-03-19
Abstract: 1,043,261. Thermal regenerators. SVENSKA ROTOR MASKINER A.B. March 19, 1963 [March 21, 1962], No. 10769/63. Heading F4K. A rotary heat regenerator contains a sealing arrangement, which comprises position sensing and actuating means, for maintaining a preferred sealing relationship between the relatively rotatable parts 10 and 18 regardless of relative distortion between the said parts. An annular seal assembly 26 is connected by an arm 27 to a radial arm 22, pivoted at 24 adjacent to the rotor post 11. The sensing means comprises a disc 38, having a series of spaced pins 42 attached thereto, which is placed between limit indicating means 34 and 36 which are attached to the rotor housing. If the sensing means, which rotates with the rotor 10, moves axially relative to 34 and 36, these projections will come into contact with the pins 42, thus introducing a rotation to the disc and thus to the threaded tube 43, to which it is attached. Since the tube passes through internally threaded apertures in the support means 44, any rotation of this tube produces axial movement which is communicated to the pivotal connection 47, and hence to the annular seal 26, thus moving the seal relative to the rotor housing.

Abstract: 527,644. Substituted acetic acids. DU PONT DE NEMOURS & CO., E. I. April 11, 1939, No. 11024. Convention date, April 9, 1938. [Class 2 (iii)] Substituted acetic acids are obtained by subjecting formaldehyde, or a polymer thereof, and an inorganic acid to the action of carbon monoxide, preferably at raised temperature and pressure, the molecular proportion of the acid being greater than one-tenth of that of the formaldehyde, and the reactants being anhydrous or containing such a limited amount of water that the product is not substantially hydrolysed to hydroxyacetic acid. Specified inorganic acids are hydrochloric, hydrochromic, hydrofluoric, and phosphoric acids, hydrogen sulphide, sulphuric or sulphurous acid, or boric acid ; the products are respectively chloracetic, bromacetic, fluoracetic, phosphoroacetic, mercaptoacetic acids, or sulphuric, sulphurous or boric esters of hydroxyacetic acid. When polybasic acids are used, one or more of the hydrogen atoms may be replaced by acetic acid groups. For the weaker acids, i.e., those not capable of giving a pH of less than 6 in aqueous solution, it is desirable to add, as a catalyst, an acidic substance capable by itself of giving a pH value less than 6 in aqueous solution, e.g., hydrochloric or sulphuric acid. The process may be carried out in an autoclave, or it may be effected in a continuous manner by passing formaldehyde, acid and catalyst through a reaction zone either cocurrent or counter-current to the flow of carbon monoxide. Examples are given of the production of chloracetic and fluoracetic acids, and of sulphuric and phosphoric esters of hydroxyacetic acid.

Abstract: 513,541. Purifying phenols. DEUTSCHE ERDOL-AKT.-GES. April 12, 1938, No. 11197. Convention date, April 27, 1937. [Class 2 (iii)] In the process of obtaining pure phenols from tar oils by extracting with alkali lye and treating the alkali phenolates with an inert adsorbent the tar oil or alkali phenolate is enriched with low-boiling phenols boiling below 220‹C. The resulting mixture is extracted with alkaline lye, and the phenolate layer treated with adsorbents, whereupon the phenols are isolated by acidification, or if dilute alkali lye is used whereby free phenols are formed by hydrolysis, by extraction with solvents, such as ether or benzol. The initial enrichment with lowboiling phenols may be effected by adding such phenols as oil or as alkali phenolate, to a tar oil or by removing components of higher boiling point. For example, lignite tar fraction boiling at 170-300‹C. is distilled to remove half the volume. The distillate boiling at 170- 240‹C. containing 20 per cent. of phenols is treated with 10 per cent. alkali lye. After standing and removing any precipitate the phenolate layer is heated at 80-90‹ with steam, and is treated with lignite coke, active carbon, Fuller's earth, diatomaceous earth, aluminium hydroxide, or silica. The refined alkali phenolate is then treated with carbon dioxide, sulphuric or hydrochloric acid, and the liberated phenols redistilled if desired after pre-treating with a small amount of formaldehyde.
