Abstract: A liquid (10) stored in a generation chamber (2) is sprayed by an injection nozzle (33) using pressurized gas introduced to it. This strikes a buffer valve (4) where it is atomized. The generated mist is held in the generation chamber (2). The atomized generated mist is introduced into a particle classifier (5) and made to collide with a collision plate (52). The particles of less than 10 ?m size bouncing off the collision plate are discharged as a micro-mist from a discharge port (56) and fed to a target workpiece. The large particles deposited on the collision plate are recovered in a generator.

Abstract: There is disclosed a method and apparatus for removing inhibiting substances produced in a dehydrogenation aromatization of poly cyclic compounds, the removal and consequent refinement of the reaction products occurring within the reaction system itself. To a dehydrogenation reaction apparatus comprising an evaporation section, a distillation, section, a reaction chamber including a catalyst bed section and a reflux condenser section, raw material is fed and then evaporated. After the vapor is passed through the catalyst zone section, it is liquefied at the reflux condenser section, and a portion or whole returned to the reaction chamber. The method is effective with poly cyclic compounds that cannot easily be handled by conventional methods. The reaction is highly efficient and proceeds with minimal catalyst deterioration.

Abstract: There is disclosed a side-chain alkylation reaction wherein an alkyl aromatic compound having a benzyl hydrogen is reacted with unsaturated hydrocarbons to produce a desired target product with excellent selectivity. The reaction is conducted in the presence of an alkyl ether and an alkaline metal catalyst. In comparison with conventional methods, it was observed that target selectivity was improved remarkably when equimolar addition of the reactants was employed, that very little catalyst was needed, and that the catalyst could be treated as a linear or uniform system, allowing the reaction to be easily scaled to meet industrial requirements.
