Title: Separating acetic acid from reaction mixtures by distillation
Inventor: HOHENSCHUTZ HEINZ
IPC: C07C51/46
Filed: 1964-07-10
Abstract: In order to separate acetic acid from a reaction mixture obtained by reacting methanol, under pressure, with carbon monoxide in the presence of water and a catalyst comprising a compound of a carbonyl-forming metal of Group VIII of the Periodic system, the methanol being mixed if desired with methyl acetate and/or dimethyl ether, the reaction mixture is distilled to remove 5 to 20% of the constituents having a normal boiling point below 80 DEG  C., the mixture is then passed to a second distillation stage where the bulk of it is vaporized leaving a solution of the catalyst, the vapours being introduced into a fractionating column operated under reflux of organic constituents so as to obtain an overhead distillate containing the bulk of the water.  The required anhydrous acetic acid is withdrawn from the column as a liquid fraction.  The water distils over in the form of azeotropes with the water-insoluble, higher boiling constituents (e.g. butyl acetate and 2-ethylbutene-2-al-1) of the mixture, and the condensate separates into two phases.  The organic phase comprises the remaining low boiling constituents as well as the higher boiling constituents; and part of this organic phase is employed as reflux for the column.  The anhydrous acetic acid contains small amounts (2 to 6% by weight) of high-boiling compounds which may readily be separated from the acetic acid by further distillation.  The specified catalysts comprise (i) a halogen-free compound of a carbonyl-forming metal of Group VIII of the Periodic system and a halogen compound, or (ii) a halide of a carbonyl-forming metal of Group VIII, e.g. cobalt iodide.ALSO:Acetic acid is separated from a mixture obtained by reacting methanol with carbon monoxide, in the presence of water and a catalyst, e.g. cobalt iodide, by distilling off between 5 to 20% of the low-boiling constituents of the mixture (i.e. those constituents, such as methyl acetate, having a normal boiling-point below 80 DEG C), passing the mixture to a second distillation stage where the bulk of the mixture is vaporized leaving a solution of the catalyst, introducing the vapours into a fractionating column operated under reflux of organic constituents in order to obtain an overhead distillate containing the bulk of the water, and withdrawing a liquid fraction comprising anhydrous acetic acid from the column.  The water distils over in the form of azeotropes with the water-insoluble, higher boiling constituents (e.g. butyl acetate and 2-ethylbutene-2-al-1) of the mixture, and the condensate separates into two phases.  The organic phase comprises the remaining low boiling constituents as well as the higher-boiling constituents; and part of this organic phase is employed as reflux for the column.  The anhydrous acetic acid contains small amounts (2 to 6% by weight) of high-boiling compounds which may readily be separated from the acetic acid in a further distillation.  The first distillation is preferably carried out in a column operated under reflux.

The fuel assemblies 1, as shown in Fig. 2, each comprise a bundle of fuel pins 10 with helical spacing wires 11 enclosed in an hexagonal wrapper 12 having a flexible inner lining 13 with vertical corrugations complementary to the contours of the close packed, wirewrapped fuel pins 10. Althoughnot shown, the wrapper. 12 and the lining 13 are interconnected at the upper end of the wrapper to close the interspace, this being open however at the lower end. Bleed holes 22 in the lining 13 enable the interspace to be evacuated of gas during submersion of the fuel assembly in the pool of coolant and also provide for restricted flow of coolant through the interspace. Each fuel pin 10 contains driver fuel in the central region and breeder material in the upper and lower regions. In the upper and lower regions, the flexible lining 13 and wrapper 12 are spaced apart by rods 15. In the upper region of the hexagonal wrapper 12, expansible envelopes 18 are attached one to each side as shown in Fig. 4. These envelopes 18 are fabricated from two stainless steel sheets sealably welded together at their edges and are both secured by upper and lower stainless steel straps (19, 20) (Fig. 3, not shown) and enclosed by a thin outer stainless steel sleeve 21 of hexagonal cross-section. Each envelope 18 is connected to the interior of the wrapper 12 by a pipe (not shown) extending- downwardly to. the lower region of the fuel assembly and occupying a peripheral fuel pin position. In operation, upstream coolant pressure is transmitted along the pipes to the envelopes 18 which are inflated by compression of He gas contained therein. The inflated envelopes 18 radially expand the sleeves 21 into bearing contact with each other, the combined thrusts of the fuel assemblies being reacted by a girdle (not shown) surrounding the upper region of the core. The upstream coolant pressure also deflects the flexible inner linings 13 radially inwardly to clamp the fuel pin bundles. Each fuel assembly, being in firm contact with neighbouring assemblies, is constrained against bowing. Because the inner lining is flexible, it can accommodate fuel pin swelling without jamming.
