Title: Process for the conversion of diphenic acids into other diphenylcarboxylic acids or their derivatives
IPC: C07C51/41
Filed: 1955-04-12
Abstract: Diphenylcarboxylic acids and salts or other derivatives thereof are produced by a process comprising heating at temperatures between 340 DEG  and 500 DEG  C. the dipotassium salt of a diphenic acid, optionally containing such substituents as fluorine, chlorine, methyl or ethyl groups, and then, if desired, converting the salts so obtained into the free carboxylic acids or their derivatives. Catalysts which may be employed include cadmium, zinc, iron or lead or compounds thereof and catalyst carriers may be used. Increased, normal or decreased pressures may be used.  The reaction may be carried out under carbon dioxide or nitrogen.  The starting material may be heated whilst stirring or in the form of thin layers and may be mixed with inert substances e.g. sand, coke, metal fragments, or potassium carbonate, sulphate or chloride.  Mixtures which yield the potassium salt may be employed as starting material, e.g. diphenic anhydride and potassium carbonate.  Products of the process mentioned include diphenyl 4,41-dicarboxylic acid which may be substituted and diphenyl-4-carboxylic acid.  In the example the dipotassium salt of diphenic acid is heated with cadmium oxide, zinc oxide, litharge or metallic lead in an atmosphere of carbon dioxide under pressure.  The crude product is dissolved in hot water, the solution is filtered to remove diphenyl and the metallic oxide, and treated with hydrochloric acid.  The precipitated mixture of acids is purified by boiling with methanol and consists of diphenyl mono- and di-carboxylic acids, especially the 4-monocarboxylic acid.  The 4,41-diphenyl dicarboxylic acid is converted to the dimethyl ester.

Abstract: 1,174,982. Calibrating infrared analyzers. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. March 7, 1967 [April 1, 1966], No.10648/67. Heading G1A. [Also in Division G4] Apparatus for calibrating an automatic analyzer comprises means for passing a first reference substance having a composition near the bottom of the analyzer scale through the analyzer, means for comparing the output of the analyzer with a fixed reference value and adding a voltage to the analyzer output so as to neutralize the difference, means for passing a second reference substance having a composition near the top of the analyzer scale through the analyzer and means for comparing the analyzer output with a second fixed reference value and multiplying the analyzer output by a factor such that the difference is neutralized. In an infrared gas analyzer the test gas is periodically cut off by a valve 4, Fig. 1, and replaced by a first reference gas. The analyzer output which is fed through an adjustable potentiometer 14 and an adjustable bridge circuit 15, 16 to a recorder 10 is compared in a differential amplifier 19 with a first reference value set on a potentiometer 20. The difference output from amplifier 19 is fed to a motor 24 which adjusts the potentiometer 15 and so adds a voltage to the analyzer output so as to reduce the difference between the inputs to amplifier 19 to zero. Valve 5 then switches over to admit a second reference substance to the analyzer and the output is this time compared with a second reference value set on potentiometer 21. The difference output of amplifier 19 is now connected to a motor 25 which adjusts the potentiometer 14. The switching of the valves 4 and 5 and the relays 51 and 46 are controlled by a motor operated cam circuit, Fig. 2 (not shown). In a modification Fig.3 (not shown) the potentiometers 14 and 15 are replaced by a plurality of fixed resistors in series, appropriate combinations of which are selected by counters which are operated until the output of amplifier 19 is reduced to zero.
