[求助] 聚吡咯合成问题 谁做过 已有1人参与

本人看一篇文献合成聚吡咯,具体方法如下:

PPy was synthesized by an oxidation treatment of pyrrole (3 mL, AR, Aladdin Chemical Co. Ltd) using (NH4)2S2O8 (1 g, AR, Sinopharm Chemical Reagent Co. Ltd) as the oxidant. Aer CTAB (1 g, AR, Sinopharm Chemical Reagent Co. Ltd) was dissolved in 40 mL aqueous solution at 0 C, the monomer was dropwise added to the solution and stirred for 10 min, and then the oxidant solution (5 mL) was dropwise added to the solution and stirred for 3 hours to complete the reaction. the reaction product was moved to a separation funnel and an excess amount (over twenty times the reaction solution) of methyl alcohol was poured into the separation funnel and the PPy nanoparticle precipitate was dried in a vacuum oven at room temperature.

我还没做这个反应,但是有个地方没看明白,反应完倒入分液漏斗中,加入大量乙醇后,下一句怎么就固体聚吡咯颗粒真空常温干燥了呢?反应完就应该有固体产物了吧,为什么要分液漏斗分离呢?乙醇是洗涤的作用吧?
