Title: Production of 2,4,5-trifluorobenzoic acid
Inventor: NIIZEKI SHUSUKE
IPC: C07C51/38
Filed: 1987-12-18
Abstract: PURPOSE:To simply obtain the title compound useful as an intermediate raw material for medicines, agricultural chemicals, etc., in good yield at a low cost, by subjecting 3,4,5,6-tetrafluorophthalonitrile as a starting raw material to three- stage reactions of defluorinating reduction, hydrolysis and decarboxylation. CONSTITUTION:3,4,5,6-Tetrafluorophthalonitrile expressed by formula I is reacted in an aqueous medium by adding a solid metal, such as metallic an, and a mineral acid, such as hydrochloric acid, to adjust pH to 3-6. The defluorinating reduction is carried out to provide 3,4,6-trifluorophthalonitrile expressed by formula II, which is then hydrolyzed in an aqueous solution of an inorganic acid, such as sulfuric acid, at 100-180 deg.C to afford 3,4,6-trifluorophthalic acid expressed by formula III. The resultant 3,4,6-trifluorophthalic acid expressed by formula III is refluxed and decarboxylated in the presence of water or an organic solvent, such as xylene, and a nitrogen-containing organic base without containing N-H bond, preferably without isolating intermediate products in respective steps to afford continuously the aimed compound expressed by formu la IV useful as an intermediate raw material for photosensitive materials and functional resins, etc.

Filed: 1990-11-20
Abstract: PURPOSE:To obtain an electrode pad for an RF probe with an improved contact property by forming a gold plating layer with a specific thickness on an uppermost layer of the electrode pad. CONSTITUTION:A surface of Au plated layer 6 which is formed by Au plating on electrode pads 2 and 3 has recessed and projecting parts and also the Au plated layer 6 is softer than Au deposition layers 2 and 3. Also, since its thickness is equal to or more than 1mum, a production error (approximately 1mum) at a metal conductor line 4 can be canceled out when an RF probe is allowed to contact the electrode pads 2 and 3, thus achieving an improved contact property. Although the Au plated layer 6 is formed on the Au deposition layers 2 and 3, a lower-layer metal may be any thing in the case of the uppermost layer.

Abstract: PROBLEM TO BE SOLVED: To automatically suppress vibration if the vibration is generated during control. SOLUTION: An IMC control system consists of 1st and 2nd subtraction processing parts 3 and 8, a manipulated variable arithmetic part 4, and an internal model output arithmetic part 6b. A model output value peak detection part 9 detects the peak of a model output value ym and a controlled variable peak detection part 10 detects the peak of a controlled variable (y). A state decision part 11 when judging that vibration occurs to the control outputs a correction instruction signal. Once the correction instruction signal is outputted, an internal model parameter correction part 12 calculates correction parameters of an internal model from the peak controlled variable, the amplitude of the controlled variable (y) based upon the peak model output, and the amplitude of a model output value ym. Consequently, internal model parameters stored in an internal model storage part 6a are corrected.
