的确,正如专家所说的,FeCl2在空气中非常容易氧化,但是,我们做了相关的实验,在其他条件都相同的情况下,如果不加FeCl2,混合溶液是不会聚合的。这可能是因为FeCl2在聚合溶液中会沉到容器底部,聚合溶液呈油状,这样会减缓FeCl2的氧化,对聚合反应的影响不显著。 [ Last edited by 进城 on 2011-2-21 at 11:13 ] |

Indeed, as the experts pointed out, FeCl2 is very easily oxidized in air, however, experiments we have done showed that, with all other conditions being the same, aggregation dose not occur when FeCl2 is not added to the mixed solution. This may be attributed to that FeCl2 in the aggregated solution sinks to the bottom of the solution container, and that the polymerization solution is oily, which slows down the oxidation of FeCl2, thus exerting an inconspicuous effect on the polymerization reaction. |
