Title: Ozonization of dihydro-pyran compounds, the products therefrom, and the production of amino-acids therefrom
IPC: C07C51/34
Filed: 1959-07-03
Abstract: Ethylene, propylene, styrene, acrylates, methacrylates and like monomers are polymerized utilizing ozonization products of 3 3,4-dihydro-1,2-pyran-2-carboxylic acid and salts and esters thereof as polymerization initiators.  Specification 866,391 is referred to.ALSO:The invention comprises the ozonization product of 3 : 4-dihydro-1 : 2-pyran-2-carboxylic acid or a salt or ester thereof, which contains active oxygen and does not undergo violent decomposition when subjected to thermal or mechanical shock.  The products, presumably ozonides, are prepared by passing an ozone containing gas through an ozone-inert solvent solution of the acid, as a salt thereof e.g. an alkali metal, magnesium, calcium, ammonium or substituted ammonium salt, or an ester thereof e.g. an alkyl, aryl, aralkyl or heterocyclic ester thereof.  The reaction may be effected at -75 DEG  to +75 DEG C. in, as solvent, water, a lower fatty acid, a lower aliphatic alcohol or ester thereof, a hydrocarbon or a halogenated hydrocarbon.  The ozonization products may be used as polymerization initiators (see Group IV(a)).  The ozonization products may be converted into hydroxy glutaric acid or a salt, ester or lactone thereof, or mixtures thereof by reaction with water to effect cleavage thereof and simultaneously or successively with an oxidising agent to effect partial oxidation thereof.  Cleavage is preferably effected with water containing an acidic substance at elevated temperature.  The partial oxidation may be carried out with air, oxygen containing if desired a small amount of ozone, hydrogen peroxide, cupric oxide, a hypochlorite, oxides of nitrogen or potassium permanganate.  Hydroxy glutaric acid and/or its lactone may be isolated from the product.  Preferably, however, the product is reacted with ammonia at an elevated temperature to form the ammonium salt of pyrrolidone carboxylic acid.  This reaction may be effected at 250 DEG -350 DEG C. in a sealed vessel.  The resulting pyrrolidone carboxylic acid may be converted into DL-glutamic acid by hydrolysis. Examples describe the ozonization of the dihydropyran carboxylic acid, its sodium salt and ethyl ester and conversion of the product into DL-glutamic acid as above specified.  The dihydropyran carboxylic acid is prepared by oxidation of acrolein dimers, stabilized by oxalic acid, following the procedure described in Specification 866,391.

Abstract: 633,969. Control lever mechanism. HERCULES CYCLE & MOTOR CO., Ltd., and YAPP, T. A. Aug. 19, 1947, No. 22947. [Class 136 (i)]. A control of the type adapted to be mounted on the handle-bars, or on one of the frame members of a cycle and connected to the gear selecting mechanism by a flexible cable which is under tension except when top gear is engaged comprises a finger lever 17 and a plate or segment 23 to which the cable 28 is connected each mounted for purely angular movement about a fixed pivot 31, the finger lever having on one edge angularly spaced projections 20, 21 between which lies a peg 26 on the segment and the segment having on its periphery angularly spaced teeth 24, 25 co-operating with a spring pressed pivoted pawl 34 which is adapted to be engaged by one of the projections 20 or 21 on the finger lever to move the pawl clear of the teeth on the segment when the lever is moved in a direction to release the cable. The pawl 34 is pivotally mounted on a stud 35 and is urged by a spring 36 to cause a tooth 37 on the pawl to engage one of the teeth 24 or 25 in the segment. An extension of the pawl terminates in a nose 38. To change from bottom gear, Fig. 3, to normal gear, Fig. 4, the lever 17 is moved in an anti-clockwise direction causing the projection 20 to engage the tooth 37 and move the pawl outwardly against the spring and clear of the tooth 24. The tension in the cable 28 causes the segment to move in an anti-clockwise direction to the position shown in Fig. 4. The horn 21 acting on the nose 38 effects the change from normal to top gear. To change down, the lever 17 is moved clockwise and the engagement of the peg 26 with projection 20 causes the segment to move angularly with the lever until the pawl rides over and engages with the tooth 25. Further clockwise rotation of the lever causes the segment tooth 24 to engage with the pawl.

Abstract: 639,120. Combustion processes ; coking and gasification processes. STANDARD OIL DEVELOPMENT CO. Aug. 6, 1946, No. 23325. [Classes 51 (i) and 55 (i)] A process for supplying heat to a heat consuming operation which comprises burning solid carbonaceous material in the presence of an oxidizing gas while in the form of a bed of fluidized solids having a relatively high carbon content to produce combustion gases containing substantial quantities of carbon monoxide, passing said combustion gases, together with at least sufficient oxygen to convert the carbon monoxide therein to carbon dioxide, through at least one bed of fluidized carbonaceous solids of relatively low carbon content under conditions to produce a final gaseous combustion product consisting substantially entirely of carbon dioxide, withdrawing hot solid residues from said beds of relatively high and low carbon content and utilizing at least part thereof to supply heat to said heat consuming operation. Fig. 1 (not shown), illustrates a heater suitable for carrying out the above dual combustion process and this heater is utilized in the system applied to the carbonization of coal and the generation of gas shown diagrammatically in Fig. 2. Fluidized coal fed from a hopper 1 is carbonized at 1,000-1,400‹ F. in a carbonizer 10 as a fluidized bed of material over a grid 9, the volatile carbonization products being led off by a pipe 18 after passing through a separator 15, and the fluidized coke produced is burnt in a heater 25 by the dual combustion process using a coke bed 30 of high carbon content and another 32 of low carbon content preheated air being supplied through the pipes 23, 24. Fluidized residues from the beds 30 and 32 pass by pipes 41 and 61 respectively to a carbonizer 10 and by pipes 42 and 62 to a gas generator 45 wherein passage of steam into the fluidized solids bed 43 kept at 1,600-1,800‹ F. produces water-gas which is vented off through the pipe 50, the residual solids being drawn off through a pipe 52 and recirculated to the heater 25 via a steam boiler 59 said solids being carried by flue gases introduced through a pipe 55. Control of the combustion in the heater 25 may be influenced by the addition of oxygen through a pipe 35, inert gases through a pipe 36, or by the recirculation of fluidized residues from the bed 32 through a boiler 66. In preparing the fuel bed 32 catalytic material containing iron oxide, high iron clays, red mud or spent cracking catalysts may be included. Oxygen may be supplied direct to the bed 32 of the heater 25 or under certain conditions, such as short contact times, sufficient oxygen to complete the conversion to carbon dixoide may be carried through the lower fluidized bed 30. Fig. 3 (not shown), illustrates a modification in which the directions of circulation of fluidized are modified and steam is used to convey the solids to the gas generator.
