Patent GB-776790-A (GB)
Title: Manufacture of diphenylol methanes
Filed: 1954-08-31
Abstract: Dihydroxy-diphenylmethanes are prepared by reacting a mixture of two or more mols. of phenol with a mol. of formaldehyde at an elevated temperature in the presence of an aqueous solution of an acid catalyst, the process being such that one-tenth to six mols. of hydrochloric acid or sulphuric acid are present per mol. of phenol, the phenol is present in excess of its solubility in the aqueous acid catalyst, the reaction mixture is in the form of a two-phase system, the aqueous phase comprises some formaldehyde in solution, the organic phae comprises substantially all the phenol in admixture with some of the formaldehyde, the mixture is heated to between 25 DEG and 11 DEG  C. and the dihydroxy-diphenylmethanes are recovered from the organic phase. Four to five mols. of phenol per mol. of formaldehyde and reaction temperatures of 55-75 DEG  C. are preferred.  At temperatures of 65-75 DEG  C., the formaldehyde is completely reacted in 5-15 seconds.  The large amount of acid catalyst used gives a rapid reaction, a high yield and absorbs the exothermic heat of the reaction.  Losses of phenol as by-products, e.g. by sulphonation when sulphuric acid is used as catalyst, may be avoided by having at least about 4 mols. of water per mol. of acid. In Fig. I (not shown), an apparatus for the continuous production of dihydroxy-diphenylmethanes is described wherein streams of phenol and formaldehyde are mixed with acid and water, the mixture is passed to a reactor having agitating means and after reaction of all the formaldehyde the resultant two-phase mixture is discharged and separated in a decanter, the acid from the aqueous phase being recycled and the organic phase, neutralized, e.g. with sodium hydroxide, lime or zinc oxide, heated to evaporate phenol which is recycled and the products separated.  The products comprise varying proportions of 2:21-, 2:41- and 4:41-dihydroxy-diphenylmethanes, resinous novolak condensation products and unreacted phenol. 4:41-Dihydroxy-diphenyl-methane may be separated from the reaction products by recrystallization from acetic acid.  In examples: (1) phenol and formaldehyde with sulphuric acid as catalyst were reacted continuously as described above; (2) formaldehyde was added slowly to a two-phase reaction system of phenol, hydrochloric acid and water, and the products separated from the organic phase.

Title: Manufacture of resorcinol
Inventor: THOMPSON BERNARD HAMMOND MARKH
IPC: C07C37/74
Filed: 1958-08-08
Abstract: A process for the manufacture of resorcinol by the catalytic cleavage of a reaction mixture containing meta-diisopropyl benzene dihydroperoxide derived from the oxidation of meta-diisopropyl benzene, comprises heat-decomposing the material contained in the cleavage reaction product which is less volatile than resorcinol while passing steam through said material, simultaneously distilling off the additional quantities of resorcinol and meta-isopropenyl phenol so formed, separating any oil phase from the aqueous distillate and subjecting the latter to flash distillation to obtain an overhead fraction containing water and meta-isopropenyl phenol and a substantially anhydrous residue fraction containing resorcinol substantially free from metaisopropenyl phenol.  The heat treatment may be carried out after removal or neutralisation of the catalyst employed in the cleavage reaction and after removal of acetone, unchanged hydrocarbons and free resorcinol or concurrently with the distillation of the cleavage reaction product without prior removal of any of the free resorcinol.  Superheated steam is preferably employed in the process.  The distillate from the thermal decomposition is preferably maintained at a pH of at least 4.  The flash distillation conditions specified range from a pressure of about 50 mm. at a wall temperature of about 170 DEG C. up to atmospheric pressure at a wall temperature of about 210 DEG C. An example is furnished in which resorcinol is recovered from the crude aqueous solution obtained by the acid catalysed cleavage of meta-diisopropylbenzene dihydroperoxide.  Specification 857,113 also is referred to.

Abstract: 810,867. Aircraft indicating instruments. SMITH & SONS (ENGLAND) Ltd., S. Nov. 8, 1956 [Sept 9, 1955], No. 25865/55. Class 4. [Also in Group XL(c)] A navigational instrument for aircraft comprises a case (not shown) closed at the front by a viewing window 1 on which is marked a luminized representation 2 of an aircraft wherein the intersection of the " wings " and " fuselage " lies on the axis of the instrument. A conventional bearing scale 3 is mounted for rotation about the axis under the control of a gyro-compass 7 operating through a repeater 4 and gears 5 and 6 whereby the position of scale 3 in relation to pointer 2 indicates magnetic heading of the aircraft. A carrier 8, provided with gear 11 is co-axially mounted behind scale 3 in frictional engagement for rotation therewith, though it may be rotated relatively to the scale by knob 9 operating through gears 10 and 11. Carrier 8 supports a moving coil meter movement 11a provided with parallel arms 12, 13 to support a pointer 14 which may therefore swing vertically and rotate about the instrument axis. Swinging movement of the pointer 14 is determined by a demodulator 15 energised from a differential device 21 supplied with signals dependent on the size of the angle between pointer 14 and a further pointer 16. The pointer 16 consists of two radial elements mounted on a gear ring 17 mounted for rotation about the axis under control of a gear 19 and a repeater 18 energised by radio equipment responsive to the direction of a ground transmitting station from the fore-and-aft axis of the aircraft. The distance of the aircraft from the ground station is indicated on a counter 22 and a further counter 23 displays the heading of a selected track, being driven in accordance with the relative positions of scale 3 and carrier 8 fed through a differential 24. The magnetic heading of the aircraft is indicated by the intersection of the " fuselage " line of pointer 2 with bearing scale 3, and carrier 8, when set by knob 9, adjusts pointer 14 to give an indication of the known heading of a desired track and pointers 2 and 14 together indicate the angle which the fore-andaft axis of the aircraft makes with the track. To follow a selected heading, pointer 14 is placed in its mid-vertical position and aligned with pointer 16, pointer 16 being aligned with the selected heading on scale 3.
