在进行分馏的过程中，由于水和反应物会形成共沸，故在溜出水的同时会带走一部分反应物，这就会使得产率下降，同时在过滤中和晶体转移过程中会损失产物，也会使得产率下降，所以实验误差比较大

結果 (中文) 2:

The fractionation process, because the water and the reactants can form azeotrope, the smooth water will also take part of reactant, it will make the yield decreased, at the same time in the filter neutralization crystal transfer process will be loss of product, can make the yield decreased, so the experimental error is relatively large
