Title: Process for oxidation of cyclohexane and for the production of adipic acid
IPC: C07C/
Filed: 1960-06-17
Abstract: Adipic acid is made by reacting cyclohexane in the liquid phase with molecular oxygen at a temperature of from 100 DEG C. to 140 DEG C. to oxidize from 5 to 15% of the cyclohexane present and to produce a liquid product comprising cyclohexanol, cyclohexanone and unreacted cyclohexane, separating cyclohexane from the liquid product and reacting the residual liquid with molecular oxygen in the presence of a solvent to produce adipic acid.  The first oxidation may be effected in the presence of a metal oxidation catalyst, preferably a cobalt salt soluble in cyclohexane, such as cobalt acetate or naphthenate. Cyclohexane may be present as an initiator.  The oxidation can be carried out in a series of reaction zones, preferably four, each equipped with cooling means and agitators and constructed for operation in a pressure range of 100 to 500 p.s.i.g. Cyclohexane is fed in at a space velocity of from 2 to 125 volumes per liquid volume per hour.  Air, oxygen or oxygen-enriched air may be employed.  The cyclohexane may be removed from the product of the first stage by distillation or other suitable means. The residual oil containing cyclohexanone and cyclohexanol in a weight ratio of 0.9 to 1 or more is a solvent such as acetic, propionic, butyric, iso-butyric or valeric acid and oxidized at a temperature in the range of 70 DEG  to 105 DEG C. at pressures between 85 and 400 p.s.i.g.  The liquid product is discharged into a crystallization zone to obtain adipic acid crystals which are purified by recrystallization.  Specification 941,662 is referred to.

Title: Improvements in or relating to boilers
IPC: F22B21/34
Filed: 1957-07-05
Abstract: 871,508. Hot-water boilers. ROSSI, G. July 5, 1957 [July 13, 1956], No. 21384/57. Class 64(1) In boilers for producing hot or superheated water, water is supplied (or returned from use) to a duct C and branch tubes D, the duct C passing axially through a header A whilst its branch tubes D pass -co-axially into downcomers 1 extending from the header. The incoming water is thus heated before mixing with the boiler water which it draws down the downcomers 1. Between the downcomers 1 and risers 2, with which the downcomers communicate through a lower header B, there may be a gas-pass from a furnace whose wall is formed by the risers 2. In Fig. 1 (not shown), the risers 2 communicate directly with a single upper header A, some of the heated water passing back down the downcomers 1 whilst the rest passes through apertures into an upper outlet section of the duct C. This outlet section is divided, by a horizontal partition in the duct (similar to the partitions 3 in the duct C in Fig. 5), from a lower inlet section. In a similar arrangement, Fig. 4 (not shown), the outlet section is formed in the header A by a separate duct parallel with an undivided inlet duct C and the risers 2 are separated sufficiently from the downcomers 1 to form a furnace space therebetween. In Fig. 2 there are two upper headers A, A<SP>1</SP> the higher A of which contains an undivided inlet duct C whilst the lower contains an outlet duct 5 with apertures 7. A furnace, Fig. 3, may be formed by two spaced rows of tubes, in each of which rows risers 2 alternate with downcomers 1, the branch tubes D, as before, passing from the inlet duct C into the downcomers. The risers and downcomers, in this case, pass from the central, upper header A and intercommunicate by way of header A a central, lower header or by way of two parallel lower headers corresponding to the two tube rows. In Fig. 5 a furnace is formed by the interdigitation of the downcomers 1 and risers 2 of each of two units, each of which has extra riser tubes 8 in gas-passes beyond the furnace as well as straight downcomers 1 and risers 2 of U-form both spaced to allow interdigitation with the tubes 1, 2 of the other unit. As in Fig. 1 (not shown), the hot water which does not recirculate from the upper headers A to the downcomers passes through apertures 7 to an upper, outlet section of the duct C, divided by a longitudinal partition 3 therein from a lower, inlet section which supplies the branch tubes D.

Title: Improvements relating to the manufacture of textile fabric
IPC: A41B3/10
Filed: 1938-07-19
Abstract: 497,568. Compound fabrics. KOVES, N. July 19, 1938, No. 21408. [Class 140] Stiffened compound fabrics for collars, cuffs, &c. are made by subjecting an assembly of two outer layers of non-thermoplastic fabric and an intervening layer of fabric composed of or containing cellulose derivative threads, after treatment with a volatile or low-boiling solvent for the cellulose derivative, to pressure between an upper heated surface and a lower, cold, absorbent, water-containing surface. The upper fabric layer is thereby more intimately united to the interlayer than the lower, and the porosity of the interlayer is maintained or increased by the rising water vapour. The compound fabric, while still warm and damp, after pressing, may be soaked in water to increase its flexibility. The outer fabrics may be cotton or linen and the inner fabric cellulose acetate. The solvent may be acetone, ethyl or butyl acetate, ethyl lactate, or a mixture with or without methylated spirit.
