聚吡咯合成問(wèn)題 誰(shuí)做過(guò) 已有1人參與

本人看一篇文獻(xiàn)合成聚吡咯,具體方法如下: 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. Aer 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. 我還沒(méi)做這個(gè)反應(yīng),但是有個(gè)地方?jīng)]看明白,反應(yīng)完倒入分液漏斗中,加入大量乙醇后,下一句怎么就固體聚吡咯顆粒真空常溫干燥了呢?反應(yīng)完就應(yīng)該有固體產(chǎn)物了吧,為什么要分液漏斗分離呢?乙醇是洗滌的作用吧? |
