Abstract: PROBLEM TO BE SOLVED: To provide an easy and efficient process for industrial production of 4-fluoro-3-trifluoromethylphenol that is important as a synthetic intermediate for N-benzyl-2-(4-fluoro-3-trifluoromethyl-phenoxy)butanoic acid amide useful as a herbicide. SOLUTION: In the presence of sulfuric acid, water is used in an amount of about 1-20 pts.wt. per 1 pt.wt. of 4-fluoro-3-trifluoromethylaniline to prepare 40-fluoro-3-trifluoromethylaniline sulfate. This sulfate salt is diazotized to prepare about 8-25wt.% aqueous solution of the diazonium salt (after diazotization, the sulfuric acid is maintained in about 30-70wt.% as added sulfuric acid). The resultant diazonium salt (its sulfuric acid concentration is kept at about 30-70wt.% as the amount of sulfuric acid added) is hydrolyzed in an aqueous copper sulfate solution whereby 4-fluoro-3-trifluoromethylphenol can be produced in an industrial scale.

Title: Pneumatic driving device
Inventor: ITOI SHIGERU
IPC: F15B15/10
Filed: 1987-12-03
Abstract: PURPOSE:To reduce a driving air consumption by forming, in a valve body, a narrow hole which introduces the driving air from a supply source directly to a supply/discharge chamber. CONSTITUTION:A narrow hole 21 which communicates a supply passage 7 with a discharge passage 9 is formed on a valve body 14. When a driving diaphragm 6 is thereby kept in a specified position, driving air from a supply source is directly introduced through the narrow hole 21 to a supply/discharge chamber 26, while the same amount of driving air is introduced from a gap between the valve body 14 and a lower valve seat 13 through the discharge passage 9 to a discharge chamber 29. As a result, the pressure difference between the fore and aft portions of the narrow hole 21 which determines the passing amount of the driving air is eliminated. The driving air amount from the supply source to the atmosphere is thus decreased to enable the reduction of driving air consumption.
