[交流] 求高手翻译(不要翻译软件修改修改的)

首先将丙烯酰胺、季戊四醇和硝酸铈铵分别配制成一定浓度的水溶液。向反应瓶中加入50mL的AM溶液和一定体积的季戊四醇溶液。反应瓶经充分除氧后密封,用注射器向反应瓶中加入一定量的硝酸铈铵溶液,震荡反应瓶,混合均匀,然后将反应瓶置入一定温度的恒温槽中,反应一定时间,用一定量的丙酮沉淀。沉淀物经机械切碎后,在丙酮中浸泡24h,室温烘干再经丙酮回流数小时,除去单体,在25℃真空烘箱中烘干至恒重。


谢谢高手帮忙!!!

这个也不合格,老师问我,你到底能不能弄个合格的,哎!!!

First of all, acrylamide, pentaerythrite and ammonium ceric nitrate were mixed by some concentration in an aqueous solution. 50 mL AM solution and a certain amount of pentaerythrite were added into the reaction flask, followed by deoxidization. Then some ammonium ceric nitrate was injected with a syringe, and a little vibration was made to obtain a uniform solution. The reaction system was kept in a thermostatic bath for a certain period of time. Then acetone was employed to precipitate the resultant. The product was squeezed the immersed in the acetone for 24 h. Drying was done at ambient temperature and refluxed in acetone for hours to get rid of monomers. Finally, a vacuum oven was used to dry the product to a constant weight.
