请教金属法做醇钾？ basf公司最近推出 叔丁醇钾的2-methf溶液,对你选择溶剂可能有参考: new products ktb –all-round talent is now available the newest portfolio addition expands the versatility of ktb even further what do most organic synthesis laboratories in the world have in common? potassium tert-butylate (ktb). ktb is a moderately strong base reagent that is used in many organic reactions: alkylation, arylation, hydrolysis, condensation, elimination, isomerizations and wittig reactions are just some examples that demonstrate the versatility of this particular reagent. its unique performance in terms of nucleophilicity, base strength solubility etc. has made it a favorite base for many chemists – in academia and industry. "our customers use ktb in many different reactions with very specific requirements. ktb solutions in special solvents is such a requirement and based on increasing interest in 2-methf, we have now added it to our standard product line," said mike foran, global product manager for specialty alcoholates at basf. as a solvent 2-methyltetrahydrofuran (2-methf) is becoming increasingly popular in organic synthesis. it offers unique properties such as easy product isolation (2-methf is not miscible with water), simple solvent recovery and excellent extraction yields. basf introduces ktb as a 25% solution in 2-methf as a standard product on various volume scales – from lab samples to commercial volumes. basf produces standard alcoholates such as sodium methylate (naome) in ludwigshafen, germany and more specialized alcoholates such as potassium tert-butylate (ktb) or sodium tert-amylate (sta) in evans city, usa and in ludwigshafen. 查看更多
