摘要： An image forming apparatus A includes: a light irradiation device 3 which irradiates laser light; an image carrying body 1 which is exposed to the laser light to form a latent image on the exposed portion; and an abutting member 31 which is fastened to the light irradiation device in abutting contact with a stationary member F for defining a reference position. The abutting member 31 changes in volume due to temperature fluctuation, and the light irradiation device 3 moves with respect to the stationary member F, in an opposite direction to a focal point shift which has taken place along an irradiation direction of the laser light due to the temperature fluctuation.

摘要： Provided is a method for stably and economically producing xylylenediamine with a high yield and long catalyst service life by hydrogenating dicyanobenzene that is obtained by ammoxidating xylene. By bringing an aqueous basic solution into contact with a dicyanobenzene-absorbed liquid, which is obtained by bringing an ammoxidation reaction gas into contact with an organic solvent, under specified temperature conditions, and subjecting a base and a carboxylic acid in the dicyanobenzene-absorbed liquid to a neutralization reaction so as to form an aqueous phase that contains a water-soluble salt, and then subjecting an organic phase and the aqueous phase to liquid-liquid separation so as to remove the aqueous phase, it is possible to remove the carboxylic acid contained in the dicyanobenzene-absorbed liquid with high selectivity while inhibiting loss of the dicyanobenzene. By subjecting the raw material dicyanobenzene, which is obtained by separating low boiling point compounds from the post liquid-liquid separation organic phase by distillation under reduced pressure, to hydrogenation, xylylenediamine is produced with a high yield and the service life of the hydrogenation catalyst is extended.

摘要： A method of producing xylylenediamine by the hydrogenation of dicyanobenzene obtained by the ammoxidation of xylene in a high yield while prolonging the catalyst life. In the method, a molten dicyanobenzene from which compounds having a boiling point lower than that of dicyanobenzene have been removed but compounds having a boiling point higher than that of dicyanobenzene are not removed is dissolved in a solvent containing liquid ammonia. By this dissolution, at least part of dicyanobenzene polymers precipitates as insolubles. The precipitates are removed by a solid-liquid separation. By subjecting the resulting solution containing the dicyanobenzene polymers in a reduced amount to hydrogenation, xylylenediamine is produced in a high yield and the life time of hydrogenation catalyst is prolonged.

摘要： Use of mordenite zeolite and zeolite Y as adsorbents enables a dimethylnaphthalene isomer mixture to be efficiently separated. A feedstock oil containing a dimethylnaphthalene isomer mixture including an α,α-isomer, an α,α-isomer, and a β,β-isomer is passed through an adsorbent layer (A) including mordenite zeolite together with a developing solvent. Subsequently, a liquid discharged from the adsorbent layer (A) is passed through an adsorbent layer (B) including zeolite Y. An eluent is passed through the adsorbent layer (B). The solvent is removed from the resultant eluate to obtain the α,β-isomer of dimethylnaphthalene. Similarly, the β,β-isomer of dimethylnaphthalene is obtained from the adsorbent layer (A).
