3. 阅读(翻译)以下有关反应操作的原文,请在理解基础上写出:(1)此反应的完整反应式(原料、
试剂和主要反应条件);(2)此反应的反应机理(历程)。
(1) Dipyridine chromium(VI) oxide (Note 1).
A dry, 1-l., three-necked flask fitted with a sealed mechanical stirrer, a thermometer, and a drying tube,
is charged with 500 ml. of anhydrous pyridine (Note 2), which is stirred and cooled to approximately 15°
(Note 3) with an ice bath. The drying tube is periodically removed and 68 g. (0.68 mole) of anhydrous
chromium(VI) oxide (Note 4) is added in portions through the neck of the flask over a 30-minute period.
The chromium trioxide should be added at such a rate that the temperature does not exceed 20° and in such
a manner that the oxide mixes rapidly with the pyridine and does not adhere to the side of the flask (Note 5).
As the chromium trioxide is added, an intensely yellow, flocculent precipitate separates from the pyridine
and the viscosity of the mixture increases. When the addition is complete, the mixture is allowed to warm
slowly to room temperature with stirring. Within one hour the viscosity of the mixture decreases and the
initially yellow product changes to a deep red, macrocrystalline form that settles to the bottom of the flask
when stirring is discontinued. The supernatant pyridine is decanted from the complex and the crystals are
washed several times by decantation with 250-ml. portions of anhydrous petroleum ether. The product is
collected by filtration on a sintered glass funnel and washed with anhydrous petroleum ether, avoiding
contact with the atmosphere as much as possible. The complex is dried at 10 mm. until it is free-flowing,
