Title: Process for the recovery of sulphur dioxide from gases containing same
IPC: C01B17/60
Filed: 1934-03-14
Abstract: In the recovery of sulphur dioxide from gases by washing them with a mixture of organic bases, such as aniline, toluidine, xylidine, pyridine, pyridine bases, quinoline, &c., and water and thereafter heating the reaction product, there is added to the circulating liquor, either before, during or after the absorption step, a substance or substances capable of decomposing the organic-base sulphates formed by secondary reaction (owing to the presence of oxygen) into free organic bases and water soluble inorganic sulphates.  Suitable substances are the oxides, hydroxides, carbonates or sulphites of the alkali metals, ammonium or magnesium. In addition, the effluent gas from the absorption treatment and/or the sulphur dioxide recovered in the heating step may be treated with the above substances in the presence of water, the organic base content of these gases being recovered; the liquors thus obtained may be employed in the main process.  The absorption step may be conducted at temperatures not above 35 DEG  C., and at elevated pressure.  The expulsion of the sulphur dioxide may take place at 65--105 DEG  C., and, if desired, under reduced pressure.  The vapours of the absorption agent present in the out flowing gases may be separated by cooling or condensation and returned to the absorption mixture.  The amount of the added substances may be just sufficient for the decomposition of the organic base sulphates or may be large enough to decompose residual quantities of sulphites left in the base or in the aqueous phase after expulsion of the sulphur dioxide.  In washing the gases as above described, substances with a basic reaction or a carbonate or neutral sulphite is preferably employed in washing the waste effluent gas while the sulphur dioxide is preferably washed with a bisulphite or acid sulphite, the employment of carbonates being avoided if the sulphur dioxide is to be subsequently liquefied.

Title: Controlled oxidation of unsaturated hydrocarbons
IPC: C07C45/35
Filed: 1944-05-01
Abstract: Carboxylic acids, ketones, and peroxides are produced by oxidation of an aliphatic or alicyclic hydrocarbon having an olefinic linkage between two carbon atoms of aliphatic character with oxygen or oxygen-containing gases in the presence of hydrogen bromide at an elevated temperature below that producing spontaneous combustion. Initial hydrocarbons specified are ethylene, propylene, butene-1 and -2, isobutene, pentene-1 and -2, 2-, and 3-methyl butene-1, 2-methyl butene-2, hexene-2 and -3, 4-methyl pentene-2, octene-2, cyclopentene, cyclohexene, 3-methyl cyclohexene, hexadiene-2, 4, and their homologues and alkyl derivatives.  Hydrocarbons having a terminal -CH3 tend to produce unsaturated acids, and those without may produce saturated ketonic compounds.  Those with a tertiary carbon linked to an unsaturated carbon may yield tertiary alkenyl hydro-peroxides and di-(tertiary alkenyl) peroxides.  Thus propylene gives acrylic acid, butene-1 gives 3-oxy-butene-1, and isopropyl ethylene 3-methyl-3-hydroperoxy-butene-1 and the corresponding di-alkenyl peroxide.  Alkenyl bromides are by-products of the reaction. Temperatures and other reaction conditions are generally as described in Specification 574,958.  In examples: (1) propylene, oxygen, and hydrogen bromide in the ratio 2 : 2 : 1 are passed at a space velocity of about 15 through a "Pyrex" (Registered Trade Mark) glass reactor at 224 DEG  C. to give organic acids, principally acrylic, alkyl bromide, and carboxylic compounds, mainly brom-acetone; (2) butene-2 at 217 DEG  C. and space velocity 15 similarly gives mainly crotonic acid diacetyl and unsaturated bromides; (3) cyclohexene, oxygen, hydrogen bromide, and a nitrogen diluent, in a ratio 1 : 4 : 1 : 4, at about 193 DEG  C. and space velocity of above 15 give D 2 cyclohexenone.

In a preferred method the wood is immersed in a bath consisting of 3 parts by weight of water to one part by weight of pyridine, and is then dried by air at a temperature of 60-80‹ C., from which the excess water-pyridine mixture is continually removed. The wood 8, Fig. 1, is then placed on a steel base plate 3 between the heated faces 1, 2 of a press. The plate 3 has a contoured face 4, and is located within a silicone ring 6 having a connection 9 leading to a vacuum pump. An aluminium plate 7 rests on the ring 6. Vacuum is applied via the connection 9 and pressure is then applied by the faces 1, 2. During this stage hydrolysis of the wood occurs. Further pressure is then applied so that the plate 3, Fig. 3, shapes one surface of the wood and the edges 5 thereof seal against the plate 7 and cut away scrap material. The vacuum connection is then broken and polycondensation occurs in the wood. After release of pressure the shaped component is removed from the press. In an alternative method the plate 3 is omitted and a board like component is produced, one or both faces of which may be subsequently planed. This component may subsequently be ornamented on one or both faces by applying heat and pressure as above. The ring 6 and application of vacuum may be omitted. The wood may comprise a number of pieces superimposed horizontally or side-by-side vertically. The components may be used in flooring or furniture and are wear resistant.
