摘要： Pyridine is reacted with chlorine at a molar ratio of pyridine to chlorine of 0.5-10 : 1 in a gaseous phase in the presence of at least 0.2 moles, preferably 1 to 20 moles of steam per mole of pyridine under irradiation of ultraviolet rays of 2000-5000 A, thereby producing 2-chloropyridine.

摘要： A pressurized fluid supply hose which conducts pressurized fluid discharged from a pump to a fluidically operated device is disclosed. A spiral tube formed by two spirally wound band members is fixed by caulking in one end of a steel pipe. The outer shape of the one end of the steel pipe includes a taper portion formed to slope gradually between a thin portion and an outer diameter portion. By effecting a caulking process with a caulking tool having a pressing portion extending in parallel to an outer surface of the steel pipe, the outer taper portion of the steel pipe is contracted to formed an inner taper portion at an internal surface thereof, and one end of the spiral tube is fixed to the inner taper portion. Because the spiral tube is gradually deformed along the inner taper portion of the steel pipe, it can avoided that a large clearance is formed between the two band members of the spiral tube.

摘要： Pyridine is reacted with chlorine in the presence of water by photolytic reaction under irradiation of photolytic light, using halogenated hydrocarbon such as carbon tetrachloride as a diluent. When the amount of water added exceeds at least 0.01 moles per one mole of pyridine, an effect of water addition appears, but usually addition of 0.2 to 10 moles, preferably 0.5 to 5 moles of water per one mole of pyridine makes the reaction proceed smoothly without any trouble, and ensures increase in yield and selectivity of 2-chloropyridine. The present process can be carried out in either gaseous or liquid phase.
