本発明をなすに至つた。Means for Solving the Problems As a result of various studies to achieve the above object, the present inventors have focused on the redox action of hydrogen-type cation exchange resins, and have found that they can be used as starting materials in a very simple manner. We have discovered that hydroquinone can be quantitatively produced from quinone, and based on this knowledge, we have accomplished the present invention.

よつて検出する。Example 1 Water or 10% acetonitrile-water was flowed at a flow rate of 1 ml/min using a constant flow pump into a plastic column with a length of 20 cm and an inner diameter of 8 mm filled with a hydrogen-type strongly acidic cation exchange resin with a particle size of 5 microns. I'll keep it. Next, 0.1 ml of 0.5 mM quinone is injected into the upper part of this column using a six-way valve type sample injector to bring the quinone into contact with the hydrogen-type cation exchange resin. The eluate from the column is detected by an ultraviolet absorption detector using a photodiode array placed immediately after the column.

ることが確認された。 As is clear from FIG. 1, the absorption spectrum of quinone showed a maximum absorption wavelength at 247 nm. However, the ultraviolet absorption spectrum of the eluate from the column shown in Figure 2 was clearly different from that of quinone, showing absorption peaks at 220 and 289 nm. Therefore, it was presumed that the quinone was changed into another compound with a similar structure upon contact with the ion exchange resin. Next, the spectrum of the standard solution of hydroquinone was detected and is shown in FIG. When this was compared with that of the eluate from the quinone column, their spectra matched perfectly, indicating that the quinone reacted with fixed hydrogen ions from the fixed sulfonic acid in the ion exchange resin to form hydroquinone. This was confirmed.

るので、連続変換操作が可能であつた。 In this example, the conversion reaction was carried out in a batch manner using a column packed with a hydrogen-type cation exchange resin, and the regeneration operation was performed using a regeneration solution (sulfuric acid) at regular intervals, but continuous operation is also possible. If a hollow cation exchange resin membrane was used, the reduction reaction of quinone to hydroquinone by the fixed hydrogen ions in the ion exchange resin membrane and the regeneration operation using sulfuric acid could be performed simultaneously, so a continuous conversion operation was possible.

換反応が進行していることを示した。Example 2 Using the same apparatus, eluent, and column as in Example 1, it was revealed that the conversion reaction of quinone to hydroquinone progressed quantitatively within the column.
That is, a 0.02 to 0.5 mM quinone aqueous solution was injected into the column, and a graph (calibration curve) showing the relationship between the concentration and the absorbance of the absorption spectrum (289 nm) of hydroquinone eluted from the column was created.
As a result, it was revealed that the absorbance of hydroquinone increased almost linearly in proportion to the increase in the injection concentration of quinone, indicating that the conversion reaction within the column proceeded stoichiometrically. When the conversion efficiency (yield) of quinone to hydroquinone was calculated from the absorbance of the absorption spectrum of a standard solution of quinone and hydroquinone with known concentrations, the value was 95%, indicating that the conversion reaction was almost complete. showed that.
