Abstract: Provided are an endoscope device and a connection determination method for preventing light emission exceeding an allowable amount from being performed in a state where a light guide is not connected to an endoscope. An endoscope device of the present disclosure includes a light source unit configured to supply light to one end of a light guide; an insertion member including a connecting portion detachably connected to the other end of the light guide and a distal end that emits the light from the light guide to a target region of a subject; a light receiving unit configured to receive reflected light reflected by the target region of the subject and incident from the distal end; and a control unit configured to determine a connection state between the light guide and the insertion member on the basis of information of the reflected light received by the light receiving unit.

Abstract: A method includes supplying a gas containing acrolein to a fixed bed reactor including a reaction tube to produce acrylic acid by vapor phase catalytic oxidation of acrolein. The reaction tube is packed with catalysts having different activities in such a way that catalyst layers are formed in a tube axis direction. A catalyst X having the highest activity among the catalysts contained in all the catalyst layers is placed in the whole or a part of a section up to 30% of a length of all the catalyst layers from a rearmost portion on a gas outlet side toward a gas inlet side. A catalytically active component x in the catalyst X has Mo, V, and optionally Cu. When Cu is included, its amount is 0.8 mol or less per 12 mol of Mo. A specific surface area of the catalytically active component x is 15-40 m2/g.
