Title: Improvements in or relating to the preparation of toluic acids
IPC: C07C51/265
Filed: 1953-07-01
Abstract: Toluic acids are prepared from the corresponding xylenes by oxidizing in liquid phase a material which consists essentially of such xylenes, up to about 16 per cent by weight of ethyl benzene, based upon the weight of the xylenes and ethyl benzene, and up to 30 per cent by weight of paraffins and naphthenes, based upon the weight of the xylenes, ethyl benzene, paraffins and naphthenes, with an oxygen-rich gas at a temperature of 130 DEG  to 190 DEG  C., at a pressure of 100 p.s.i.g. to 500 p.s.i.g. which does not exceed that which allows the majority of water formed to be removed as a gaseous effluent stream and using as catalyst a salt soluble in the reaction mixture selected from the group consisting of the salts of cobalt, manganese and cerium, the oxidation being carried out in the absence of a solvent and until from 10 to 50 per cent of the aromatic compounds have been converted to oxygen containing compounds, and separating toluic acids from the reaction mixture.  In examples (1) and (2) xylenes are oxidized by the process of the invention using various conditions of temperature and pressure.  (3) An apparatus for continuous reaction is described consisting of a vertical stainless steel pipe into which the xylene-catalyst mixture is charged at the top and withdrawn after oxidation at the bottom, the whole being jacketed by a water-cooling unit for controlling the reaction temperature.  Air is bubbled in at the bottom of the tube and provides sufficient agitation.  The effluent gases are condensed to recover xylene which is recycled and the cobalt catalyst used is removed from the reaction product as the cobaltous salt.  The toluic acids are separated from the non-volatile products by distillation, preferably in vacuo.

Class 100(4) A printing machine for printing in a horizontal plane 11 for recording data from a computing machine, comprises means 109, 110 for transmitting movements of each individual main rack 101 of the computing machine to each rack 127 of the horizontal plane printing unit, and means for transmitting movement of racks 127 through gears 126, 124 to type-wheels 123 carried in a support 134 which may be yiedlingly lifted to effect impression, the racks 127 always remaining in engagement with the first gear 126. Each support 134 is slidingly mounted in guides 135-138 and individually lifted by a toggle 140, 141 when a small slide 143 moves to the right, Fig. 2. One end of the toggle is connected at 183 to a lever 147 resiliently corrected by a spring 148 so that if there is any abnormal pressure upon the type wheels 123 the entire assembly yields because of the spring 148. As the supports 134 are raised a slotted connection 131, 132 allows the racks 127 to keep in engagement with the lowermost gear wheel 126 setting the type-wheel 123.
