    摘要: A near-infrared absorption spectrum of a hydrogenated compound (hydrogenated petroleum resin) in a form of a molten resin from which a hydrogenation solvent is separated in a hydrogenation solvent removing step is measured to calculate an aromatic content ratio and a softening point as physical property values of the hydrogenated compound based on analytical curve data. At least one of a temperature, pressure, reaction time and hydrogen content in a hydrogenating portion is controlled such that a difference between the aromatic content ratio and the bromine number measured in the near-infrared spectrometry and an aromatic content ratio and bromine number of a target hydrogenated petroleum resin pellet becomes small. At least one of a temperature and pressure in a thin-film evaporator is controlled such that a difference between a softening point measured in the near-infrared spectrometry and a softening point of the target hydrogenated petroleum resin pellet becomes small.

    摘要: A manufacturing method of a hydrogenated petroleum resin of the invention includes: a thermal polymerization step of thermally polymerizing a cyclopentadiene compound and a vinyl aromatic compound; a hydrogenation reaction step; and a volatile-component removal step, in which the volatile-component removal step is performed using a volatile-component removal device including: a pressuring device configured to pressurize a reaction mixture; a heater configured to heat the reaction mixture pressurized by the pressuring device under pressure; a decompression unit including a decompression space, a pressure of which is reduced and into which the pressurized and heated reaction mixture is flowed; and a path member including a flow path through which the reaction mixture passes and provided in the decompression space so that the reaction mixture flowed in the decompression space of the decompression unit passes through the flow path.
