Patent GB-649286-A (GB)
Title: Manufacture of phenol
IPC: C07C37/72
Filed: 1948-04-20
Abstract: Phenol substantially free from acetophenone is obtained from the mixture containing phenol, acetone, acetophenone and methyl styrene made by oxidising isopropyl benzene to isopropyl benzene hydroperoxide and decomposing the latter in solution in unchanged isopropyl benzene by extracting with water at 50-100 DEG  C., preferably 70-80 DEG  C., and recovering the phenol from the aqueous extract.  The process is preferably effected after acetone has been removed, e.g. by distillation.  Phenol may be recovered from the aqueous solution by any suitable method, e.g. extraction with a selective solvent such as butyl acetate or diisopropyl ether. Treatment in countercurrent is preferred.  The isopropyl benzene phase may be purified and recycled to the oxidation stage.  Thus acetophenone may be separated by distillation, methyl styrene hydrogenated to isopropyl benzene and if necessary small quantities of phenol removed by extraction with aqueous alkali metal hydroxide solution.  De-composition is effected by acids, e.g. sulphuric acid. In an example a mixture resulting from the oxidation of isopropyl benzene and decomposition with aqueous sulphuric acid is fed to a distillation column to remove acetone, treated in countercurrent with water in a tower at 70-80 DEG  C., the extracted isopropyl benzene after distillation to remove acetophenone and treatment to remove methyl styrene is recycled to the oxidation stage, the aqueous extract is cooled to 20 DEG  C. and treated in countercurrent with butyl acetate the aqueous residue being treated for solvent recovery and then passed to the first tower, phenol being recovered from the butyl acetate by distillation and finally separated from a small quantity of acetophenone by distillation.  Specifications 626,095, 629,429 and 630,286 are referred to.

Title: Production of phosphoric acid and alkali metal and ammonium phosphates
Inventor: WINNICKI HENRY STANLEY
IPC: C01B25/30
Filed: 1955-04-19
Abstract: Phosphoric acid, or alkali metal, or ammonium, phosphates are prepared by burning elemental phosphorus adjacent the top of a thin-walled, unlined, corrosion-resistant metal tower, absorbing the resulting phosphorus pentoxide in a thin film of an aqueous solution of phosphoric acid, alkali metal, or ammonium, carbonate or hydroxide covering the walls of the tower from top to bottom, removing the resulting solution from the tower, and recirculating part of the solution.  With phosphoric acid, the walls of the tower must be maintained at 60-70 DEG  C. by external cooling, to avoid corrosion, but with the alkali metal, or ammonium, phosphate solutions the walls are maintained below 100 DEG  C. by evaporating water from the solution in the <PICT:0805006/III/1> tower.  Molten phosphorus from 3 is atomized with air from 4 in burner 2 and burned with air entering dome 9 at 5.  Dome 9 has inside and outside cooling water sprays 26, 25 and dam 27 to form a pool.  Phosphoric acid, say 75 per cent, is fed from 7 to launder 6, whence it flows over weir and is uniformly distributed over the inside walls of stainless steel tower 1. Additional phosphoric acid and/or additional water may be sprayed into the tower through spaced nozzles 8.  The level of the acid pool is shown at 10.  The acid is withdrawn at 70 DEG  C. and a portion is removed to storage at 11a, while the remainder is cooled to 55 DEG C. in 12 and returned to launder 6.  The outside of the tower 1 is cooled by a water film from ring 24a.  The whole apparatus is maintained under slight vacuum by suction fan 22, so that unabsorbed gases are withdrawn at 14 through packed tower 16, where circulating phosphoric acid from 7 removes remaining phosphorus pentoxide, and moisture separator 19, where phosphoric acid mist is condensed, to stack 23.  In an alternative arrangement (Fig. 2, not shown) a solution of trona, or of sodium, potassium, or ammonium, carbonate, or hydroxide is used to produce various specified phosphates or polyphosphates.  The tower is not provided with outside cooling as the walls can be kept between 80 DEG  and below 100 DEG  C., solely by evaporation.  Carbonate or hydroxide make-up solution is added before crystallizing and dehydrating the phosphate.  The residual gases may be passed through a glass fibre-packed tower, a venturi scrubber, or an electrostatic precipitator.  Specification 246,128, [Class 1 (ii)], is referred to.
