Title: Improved process for oxidizing primary alcohols
IPC: C07C45/29
Filed: 1962-08-24
Abstract: Nickel peroxide, the black hydrous higher oxide of nickel, possibly Ni2O3.3H2O, may be prepared by treating a nickel salt (e.g. chloride, sulphate, carbonate and nitrate) with a strong oxidizing agent (e.g. sodium or potassium hypochlorite and sodium hypobromite, or sodium or potassium persulphate) in an aqueous alkaline medium or alternatively by treating nickel oxides with an alkali hypohalite in an aqueous alkaline medium.  The nickel oxide may be prepared, by treating nickel sulphate with aqueous sodium hydroxide and drying the Ni(OH)2 at 500 DEG  C.; drying NiCO3.2Ni(OH)2.4H2O for 2 hours at 500 DEG C.; or drying Ni(NO3)2.6H2O for 2 hours at 500 DEG  C.; or the commercially available Ni2O3 may be used. An example describes the addition of a solution of sodium hydroxide in 6% sodium hypochlorite to a solution of nickel sulphate hydrate (NiSO4.6H2O) in water with stirring for 30 minutes at 10-25 DEG  C.  The black precipitate is filtered, washed and dried. The compound may be used for the oxidation of primary alcohols to the corresponding acids.ALSO:Primary alcohols are oxidised to the corresponding carboxylic acids by treatment with nickel peroxide in an aqueous alkaline medium at between 0 and 90 DEG C.  Saturated, unsaturated, straight-chain, and branched, isoincluding aromatic and heterocyclic alcohols may be oxidised and in examples, ethanol, n-propanol, n- and iso-butanol, n- and iso-pentanol, n-octanol; benzyl, phenethyl, 3-phenyl -1- propyl, 2-, 3- and 4-methyl benzyl alcohols; propargyl, cinnamyl, furfuryl, and tetrahydrofurfuryl alcohols; and diisopropylidene -1- sorbose are oxidised to the corresponding acids.  The nickel peroxide may be obtained from nickel salts or oxides (see Division C1) and may be separated from the reaction product by filtration.  The free acids are obtained by acidification of the alkaline product.

[Also in Division H4] An image pick-up tube as described in parent Specification wherein highlight areas of the target are discharged by the main beam during line flyback periods, is provided with auxiliary deflection means which are energized during flyback periods so that the area discharged comprises the area about to be scanned. As illustrated (Fig. 1, not shown) the deflection means comprises an electrostatic deflection plate arranged above an apertured diaphragm at the entrance of the main anode. As an alternative it may be a conductive wall coating disposed opposite an aperture in the anode, or it may comprise a tubular element divided into sectors, in which case it may also be used to de-focus the beam during the flyback. Magnetic deflection means is a further alternative. When the tube includes a magnetic focusing lens the current through which is varied during flyback periods, the auxiliary deflection means may also be used to compensate for the rotation of the scanning lines caused by the variation of the current. During frame flyback periods the line flyback traces may be arranged to occur at the centre of the target where excessive light may be expected, or the flyback traces may be shifted to areas which are excessively illuminated under the control of information from the scene.
