Title: Separation and purification of 2-chloropyridine
Inventor: HATA HIROYUKI
IPC: C07B63/00
Filed: 1995-06-07
Abstract: PURPOSE:To easily obtain in a high efficiency high-purity 2-chloropyridine through separation and purification by adding a mineral acid to a mixed liquor comprising 2-chloropyridine and pyridine followed by conducting a steam distillation. CONSTITUTION:Pyridine is photochlorinated using water as diluent, and a mineral acid (e.g. hydrochloric acid, sulfuric acid) is then added to the resultant aqueous solution of reaction mixture containing 2-chloropyridine, 2,6- dichloropyridine and pyridine, etc., to control the pH level of the mixed liquor to 0-4. Subsequently, steam is blown into the distillation vessel holding the mixed liquor, or the mixed liquor is distilled while adding water to the mixed liquor in the distillation vessel, thus obtaining the objective 2-chloropyridine, which is useful as an intermediate for medicines and agrochemicals. By this method, the objective 2-chloropyridine can be separated and purified from the reaction mixture without the need for using any hydrogen halide unfavorable in terms of safety and human health such as carbon tetrachloride having been used conventionally.

Filed: 1981-10-21
Abstract: PURPOSE:To prevent the generation of jolting vibration in case of driving in a lock-up region by releasing the lock-up of a torque converter only for a fixed time when an accelerator pedal is released during travelling in the lock-up region. CONSTITUTION:During travelling in the lock-up region, each AND gate 10-12 of a lock-up decision circuit 9 to which the output signals of a gear position discrimination circuit 5, a speed-change detecting circuit 6 and a car-speed comparison circuit 8 are inputted outputs H level signals, and an AND gate 14 outputs a lock-up signal SL/U to energize a lock-up solenoid 16. When a driver releases the accelerator pedal when driving and the release is continued for a fixed time, the AND gate 14 brings the signal SL/U to a level L because an idle detecting circuit 19 applies a L level signal to the AND gate 14. Accordingly, a transistor 15 is at OFF, the solenoid 16 is deenergized, and the torque converter is brought to the state of the converter.

Filed: 1984-08-10
Abstract: PURPOSE:To prevent occurrence of interference fringes on images due to the interference between a reflected light from a conductive base body and a coherent light of the incident light for a long time by setting the roughness and the pitch of ruggedness of the surface of the conductive base body of a photosensitive body within prescribed values by etching.

In case of <=0.05mum roughness and >=0.2mum pitch, interference fringes occur on images because the incident light cannot be scattered sufficiently on the surface of the base body; and in case of >=3mum roughness, the adhesive strength between the base body and the thin film layer is degraded, and they are peeled partially to degrade the light attenuation characteristic of the surface potential. The roughness of the surface of the base body is set within prescribed values in this manner to prevent the occurrence of interference fringes when images are formed with the coherent light.
