Title: Process for the separation of the anti-decomposition products of cumene hydroperoxide by distillation
IPC: C07C39/04
Filed: 1955-06-09
Abstract: <PICT:0782865/III/1> The products obtained by the acid-decomposition of cumene hydroperoxide are separated by subjecting the mixture to distillation in the presence of water in a plate-type fractionating column which is operated so that pure acetone concentrates at and is withdrawn from the head of the column, while cumene and methylstyrene (both hydrocarbons being substantially free from phenol) and water are withdrawn as sidestreams; and phenol is obtained at the base of the column. This phenol contains high-boiling compounds such as cumyl phenol and it may also contain dimethylphenyl carbinol and acetophenone; but a purer phenol may be obtained by separating the carbinol and acetophenone as an additional sidestream from the column.  A reaction mixture containing phenol and acetone in equimolecular proportions, as well as cumene (5.5 per cent), methylstyrene (1.7 per cent), dimethylphenyl carbinol (1 per cent), acetophenone (1.2 per cent), a proportion of products having higher boiling points, and water (10 per cent), is introduced through pipe 1 into a 50-60 plate-column having three decanting-plates m, n, o.  The temperature at the base of the column is maintained at 120 DEG  C. by heater V.  Acetone vapours pass overhead and are condensed in condenser T, the liquid being returned to the head of the column. Acetone product is withdrawn through pipe 2.  A fraction containing a high proportion of odorous, coloured and reducing impurities is discharged through pipe 7.  A mixture rich in cumene and methylstyrene, containing only 20 parts per million of phenol, is withdrawn from decanter m, while the water constituting the decanted lower layer is returned to the column.  An aqueous solution containing 100 parts per million of phenol is withdrawn from decanter n.  A mixture containing 8 per cent of acetophenone, 1 per cent of dimethyphenyl carbinol, 90 per cent of hydrocarbons and less than 0.1 per cent of phenol is withdrawn from decanter o, while the water decanted from this plate is returned to the column.  Phenol is withdrawn from the bottom of the column through pipe 6.

Abstract: 1,197,155. Artificial limbs. OMRON TATEISI ELECTRONICS CO. 1 April, 1969 [2 April, 1968; 8 May, .1968 (3)], No. 16914/69. Heading A5R. [Also in Divisions HI and H2] A motor M in an artificial limb is controlled by means responsive to movement of a part of the body, e.g. the shoulder H, and means are provided for stimulating the pressure sensitive nerves in proportion to the motor current. The stimulating means comprises an iron cored plunger 11 which is urged against the skin by a coil 12 connected in series with a transistor T2 Whose conduction depends upon the motor current through a resistor R2, and it may be separated from the control means but is preferalbly combined therewith. In Fig. 6 pressure on plunger 11 against the force of coil 12 closes a switch S in series with the motor. A transistor T1 also in series with the motor, is for preventing the motor being overloaded, but in Fig. 8 (not shown) the conduction of this transistor is varied, to vary the motor torque, in two stages, the switch S being replaced by one having two sets of contacts which are closed in turn by increasing pressure on plunger 11, and which is not in series with the motor but changes the value of base resistor R1 In a further embodiment (Fig. 9, not shown) the plunger moves the slider of a continuously variable resistor in the base of Tl and in Fig. 10 (not shown) this variable resistor comprises a part of the body between the plunger, which is now pointed to give a variable area of contact, and a separate ellectrode. In Fig. 14 the variable resistance, repre sented at 34, is actually comprised by a fixed electrode 32 and a flexible electrode 31 of conductive rubber, separated 'by an insulant 33. The resistance depends upon the pressure on 31. In another embodiment (Figs. 11 and 13, not shown) the control unit is arranged to form a variable, pressure sensitive, capacitor with the body as one plate; the capacitor modulates the output of an osillator which is then passed through an amplifier, a detector and a filter to control the motor. The motor operates a movable finger 6a, and in Fig. 5 (not shown) four motors operate finger, wrist, elbow and shoulder respectively.
