翻译语句 1,3,5-tri-O-benzoyl-2-deoxy-2-fluoro-α-D-arabinose in dichloromethane as solvent,ethanol and 40%HBr solution reaction,adjusted to neutral,extraction,washing,drying,filtration,concentration and then with potassium tert-butanol,2-chloro-adenine,acetonitrile,CaH2 and methylene chloride reaction,after filtration,washing and other treatment,then with methanol as solvent,reaction with sodium methoxide,cooling,acid neutral regulation,after filtering,are Clofarabine.

叔丁醇钾可以在二氯甲烷中使用吗 因该不会。三氯甲烷会与强碱反应生成卡宾,但二氯甲烷只有两个氯原子,吸电子效应比三氯甲烷弱,并且氢原子多一个,所以氢的酸性比三氯甲烷弱。

请问下面那些是危险化学品或者管制品,谢谢 答要危包证先看没MSDS或者货物运行鉴定报告
