In diluted H2SO4 and heating at 85℃, the discoloration reaction of xylene cyanol FF oxidized by potassium periodate can be greatly catalyzed by ruthenium. According to this phenomenon, a new method for catalytic kinetic spectrophotometric determination of ruthenium has been developed.

在稀H2SO4介质中及85℃的加热条件下，Ru对高碘酸钾氧化二甲苯蓝FF褪色反应具有显著的催化作用，据此建立了催化动力学光度法测定痕量钌的新方法。

The company is also working on a convertible version of the car, according to the report.
