Filed: 1955-09-01
Abstract: The invention comprises substituted aralkyl carbinols of the general formula <FORM:0785389/IV (a)/1> wherein R represents a carbonyl group (-CO-) or a hydrogenated carbonyl group (-HCOH-), and the preparation thereof by condensing a ,a -dichloroacetophenone with formaldehyde in the presence of an alkaline catalyst at a temperature between 0 DEG and 40 DEG  C. to form the compound in which R is the carbonyl group, and when required, reacting this product with a low-boiling aliphatic secondary alcohol to form the compound in which R represents the hydrogenated carbonyl group.  The alkaline catalyst may be an alkali metal hydroxide, an alkaline earth metal hydroxide or a tertiary amine.  The alkaline catalyst is preferably employed in an amount between 1 and 3 per cent by weight of the reactants. The reaction with the low-boiling aliphatic secondary alcohol, e.g. isopropanol, is preferably carried out in the presence of aluminium alcoholate as catalyst, e.g. aluminium isopropoxide.  In the examples 2-benzoyl-2,3-dichloroethanol and 3-phenyl-2,2-dichloropropane diol are prepared.  Esters of the carbinols of the above general formula are mentioned.

[Also in Division C6] Fermentations are conducted in annular trays 20, Figs. 1 and 3, eccentrically mounted within a jacketed cylindrical vessel 1, which vessel is rotatable about a vertical axis 4 through an electric motor 18 and gearing 16, and is rotatable also about horizontal axis 9, 10 by an electric motor 13 or handle 14. Filling of the trays with fluid culture medium, applying micro-organism culture to the surface of the solidified culture medium in the trays and washing off the cultured microorganisms are accomplished by rotational movement of the container see Figs. 6-9, not shown. Thus, the container is brought into the horizontal position, is rotated to bring the gap 58 due to the eccentrical mounting of the trays uppermost, and the container is then brought to the vertical position in which the trays are upright. The culture surface of each tray is attended by scrapers 24 with corrugated operational surfaces. The scrapers are flexibly mounted from arms 23, the arms being fitted to shaft 21 by joints which are freely displaceable along the shaft axis. Rotation of wheel 26 in one direction imparts a rotational movement to fork 31 and nut 30. This causes screw 33, pin 34 and shaft 21 to move downwards until projections 35 disengage spring-held pins 37 from movable washer 36. At this point the scrapers have descended into an operational position above the trays and further rotation of the wheel causes rotation of the shaft and arms. Rotation of the wheel in the opposite direction first stops the rotation of the shaft and arms and then causes them to rise into the inoperative position.

Abstract: Salicylic acids of the formula <FORM:1078786/C2/1> wherein R is H, C1-C20 alkyl, C1-C20 alkoxy, F or NO2; are obtained by forming a fluid mixture of the cupric salt of the corresponding non-hydroxylated benzoic acid and a reaction medium of C6-C30 alkanes or C6-C30 cycloalkanes or their fluorinated derivatives or a mixture thereof, heating said fluid mixture at 200-300 DEG  C., contacting the mixture with an oxygen-containing gas at a temperature at which the mixture is substantially liquid and the reaction medium is not substantially attacked by oxygen, separating the product in the form of its copper salt from said mixture, and thereafter converting the copper salicylate to salicylic acid.  The oxidation can be concurrent with the heating step or it can be done at a lower temperature in a cyclic type of operation. When a fluorinated hydrocarbon is used for the medium the heating and the oxidation steps may be performed simultaneously, whereas when an alkane or cycloalkane is used the oxidation step may be performed at a lower temperature.  The copper salts to be used as starting materials may be prepared in situ by adding CuCO3, basic copper carbonate, Cu(OH)2 or oxides of copper to a solution of the aromatic acid in the reaction solvent.  Examples are given for the production of salicylic acid and 6-methyl-, 4-tert-butyl-, 5-nitro-, 6-methoxy-, 4-butoxy and 4-fluoro-salicylic acid.
