[求助] 求帮忙翻译一段中文至英文,谢谢! 已有1人参与

重结晶:将227.3g析晶滤饼加入到2L干燥的四口烧瓶中,加入454.6gTHF,升温至60-65℃,使固体完全溶解,保温10min,后降温至50℃育晶1h,降温至-15~ -10℃保温1h,过滤得滤饼219.12g,HPLC纯度99.3%。滤液450.7g,滤液回收THF后馏底用于析晶套用。


尤其是“育晶”要求翻译准确。谢谢!

Recrystalization: Add 227.3 g of filtration cake to a 2L dry flask with 4 necks to which 454.6g THF was then charged, temperature was then raised to 60-65℃ to completely dissolve the solid. The temperature was kept at that range for 10 min, then lowered to 50℃ for 1hr to start crystalization, after which, the temperature was lowered to -15~-10 ℃ for 1 hr. After filtration, 219.12g cake was obtained, the purity was 99.3% as measured by HPLC. Also obtained was 450.7g filtrate, which after the recovery of THF,  can be used as seeds for future crystalization process.
离成功还差一点
