Patent GB-365710-A (GB)
Title: Improvements in and relating to the manufacture of cellulose acetate
IPC: C08B3/06
Filed: 1930-11-25
Abstract: Cellulose acetate is separated from its solutions, for example, ripened acetylation liquors, by a process involving the neutralization of the acidic catalyst by means of a neutralizing agent in substantial excess, and separation of acetic acid by distillation under reduced pressure.  By substantial excess of neutralizing agent is meant at least 2 equivalents, for example, about 3 to 5 equivalents when sulphuric acid is the catalyst present, and at least 1,5 equivalents in the case of other acidic catalysts. An alkali salt of acetic acid is the neutralizing agent preferred, but soda ash or caustic alkali may be used.  The distillation is preferably carried out at a sufficiently low pressure as to maintain the maximum temperature at about 70 DEG  C.  The amount of acetic acid recovered by the distillation is at least 40-50 per cent, and if need be, may be over 70 per cent, without injury to the cellulose acetate. Precipitation of the distillation residue may be carried out by incorporating 60-75 per cent of the quantity of water which would be required for the cellulose acetate precipitation to commence, and submerging in customary manner in a bath of precipitating agent.  The cellulose acetate may be precipitated in shaped forms of an opaque and uniformly porous character by using the process of Specification 357,552.  In an example, (1) to 100 parts of ripened acid dope containing 1,4 parts of sulphuric acid there are added 8 parts of anhydrous sodium acetate, and the resulting solution is subjected to a slow distillation under reduced pressure until 35 per cent of the acetic acid present has been recovered; 15 parts of water are incorporated with the residue which is then ribboned between rollers or belts surfaced with absorbent material, as in the process of Specification 357,552, and precipitated in water.  According to further examples, a ripened acid dope, as in example (1), is neutralized by the addition of 3,5 equivalents of sodium acetate and (2) distilled until 45 per cent of the acetic acid has been recovered after which 13 parts of water are added, or (3) distilled until 60 per cent of the acetic acid has been recovered, when 10 parts of water are added.  The precipitation in each case then proceeds as in the first example.

Filed: 1965-08-19
Abstract: A synthetic complex phosphate salt consists of a normal phosphate of an alkali metal, e.g. Na, K, Li, Rb, Cs, and at least one phosphate of a tervalent metal, e.g. Al, B, Bi, Fe in which the molecular ratio of alkali metal phosphate to the phosphate(s) of the tervalent metal is 1:1 to 1:6.  The salt may be an orthophosphate or a pyrophosphate, wherein the cation contains respectively 2-4 or 1-2 molecules of tervalent metal phosphate per molecule of alkali metal phosphate. Preferably, the phosphate crystallites have a maximum diameter of 200<\>rA. Preparations specified are: (a) mixing an aqueous normal alkali metal phosphate solution with a tervalent metal nitrate in the correct proportions, recovering and washing the precipitate and calcining at 300-500 DEG  C.; (b) mixing an amorphous normal alkali metal phosphate with an amorphous tervalent metal phosphate in the correct proportions, adding water to form a slurry, which is heated to boil off water, and calcining at 300-500 DEG  C.; and (c) mixing an aqueous normal alkali metal phosphate with an aqueous tervalent metal phosphate, removing water and calcining the residue at 300-500 DEG  C.  The complex phosphates may be used as a catalyst in the preparation of substituted triethylenediamine.ALSO:C-Alkyl substituted triethylene diamines may be synthesized by contacting a feed stock in the vapour phase at 250-550 DEG  C., preferably 375-400 DEG  C., in the presence of ammonia in the molar ratio of 1-15, preferably 3-10 mols. of ammonia/mol. of feed stock, the feed stock having the formula <FORM:1095027/C2/1> where R is a C1-C4 alkyl group, at least one of R1 is H, the other being H or a C1-C4 alkyl group, Y is -OH or -NH2 and X is -H or -CH2CH2Y, in the presence of a synthetic complex phosphate as catalyst, which consists of a normal alkali metal phosphate and at least one phosphate of a trivalent metal, the molecular ratio of the alkali metal phosphate to the phosphate(s) of the trivalent metal being 1:1 to 1:6.  Hydrogen or inert gases, e.g. nitrogen, may also be employed in the process as a purge or carrier gas.

Title: Improvements in or relating to the dry separation of heavier particles from lighter ones, such as separation of particles of metal from sand
IPC: B03B5/44
Filed: 1938-12-08
Abstract: 522,437. Pneumatic separating. STEVENS, A. H. (Morgan Concentrating Corporation). Dec. 8, 1938, No. 35828. [Class 117] In the separation of small particles of material from a lighter matrix, such as the recovery of gold particles from dry placer sands, the sand is passed over a table of material which is porous to air and has flutes which are also porous and are arranged to provide for the passage of a greater volume of air - than the rest of the table. In one form, the separating table 18, Fig. 3, is formed of a porous material such as bonded silicon carbide grains, natural pumice, mineral filters &c. and has a central groove 18a into which lead lateral grooves 18b inclined forwardly from the feed end of the table. The table is clamped over a wind-chest 8, Fig. 5, by a supporting flange 16, and lattice framework, and flanged troughforming members 11, rubber insets 19, 20, 21 being used to prevent disintegration of the material of the table. The table and its supporting structure are, vibrated and simultaneously air is forced into the wind chest, the effect on the material fed to the trough 11 being that the heavier products sink into the grooves and gravitate to the discharge end of the groove 18a. A modification is shown in Figs. 7 and 8, in which the table 70 is provided with converging sides 72 leading to the discharge spout 73. The sides 72 .are disposed so as to leave an air space 75 above the supporting flanges 74 which are provided with apertures 74a communicating with the air chest. The grooves 18a or discharge spout leads into a channel 26, Fig. 9, to which are attached, removably, cups 28, with relatively thin porous bottoms 29 and connected by flexible hose to the air chest: The cups are seated in recesses in the bottom of the channel 26 and in a plate 30 guided on pins 34 and pressed upwards by a spring 35. The function of the cups is to re-concentrate the material passing along the channel 26 and they are periodically released for removal and replacement by a pivoted cam plate 41, actuated by a handle 43, to depress the plate 30. During operation, unauthorised access to the cups is prevented by a plate 51 and a bar 44 on the handle 43 which may be locked in position. The table is mounted through the medium of springs on a support which is adjustable about a centre, and is vibrated by a rotary unbalanced shaft whose axis is co-axial with the centre of adjustment of the support. Preferably, the air chest is shaped so as to diminish in size away from the point of entry of the air with the object of equalizing the pressure over the surface of the table.
