摘要： A molten salt electrolyzer having a metal collection chamber, an electrolysis chamber, and two or more electrolytic cell units positioned in the electrolysis chamber. Each electrolytic cell unit has a cathode having an inner space in a prism form; at least one bipolar electrode in a rectangular cylinder form and disposed in the cathode inner space; and an anode in a prism form and disposed in an inner space of the bipolar electrode. At least part of individual planes forming an outer side of the bipolar electrode closest to the cathode faces a plane forming the prism-form inner space of the cathode. At least part of individual planes forming the inner side of the bipolar electrode closest to the anode faces a plane forming the prism of the anode. At least one plane of the cathode constitutes one plane of a cathode of another electrolytic cell unit.

摘要： A solid catalyst component for olefin polymerization makes it possible to polymerize an olefin with high polymerization activity when used for an olefin polymerization catalyst, and produce an olefin polymer having a low fine powder content, a low coarse powder content, and a low volatile organic compound (VOC) content in high yield. The solid catalyst component for olefin polymerization is produced by suspending (a) a dialkoxymagnesium, and (b) at least one alcohol selected from ethanol, n-propanol, n-butanol, isopropanol, isobutanol, and t-butanol, in an inert organic solvent so that the total amount of the alcohol is 0.5 to 1.5 parts by mass based on 100 parts by mass of the dialkoxymagnesium, to prepare a suspension, and bringing (c) an internal electron donor and (d) a titanium halide compound into contact with the suspension.

摘要： For aging deformation of a reaction vessel used for production of titanium sponge by the Kroll method, the deformation of the reaction vessel can be corrected to a desired deformation. The apparatus for correcting the deformation corrects by being inserted inside of the cylindrical deformation of the reaction vessel, the apparatus has multiple cylinder arms radially extendable to a circumference, a deformation-correcting head arranged on a top part of the cylinder arm, a hydraulic power unit connected to the cylinder arm and driving the deformation-correcting head, a detecting means for the stroke of the deformation-correcting head, and a measuring means for the pressing force against the reaction vessel. Furthermore, the method for correcting the deformation of the reaction vessel using the apparatus has a step of pressing the reaction vessel while adjusting stroke of the deformation-correcting head depending on an amount of deformation of the reaction vessel.
