応用分野

使用Lithium methoxide is used in sol-gel synthesis of lithium borophosphates. It is also useful for deprotonation reactions in organic synthesis. Further, it serves as a mild base in organic synthesis especially in transesterifications.

調製方法 · 1 件

純化方法The most probable impurity is LiOH due to hydrolysis by moisture. It is important to keep the sample dry. It can be dried by keeping in a vacuum at 60-80o under dry N2 using an oil pump for a few hours. Store it under N2 in the cold. It should not have bands above 3000cm-1, IR has 1078, 2790, 2840 and 2930cm-1 in KBr. [Suebold J Org Chem 21 1561956, Beilstein 1 IV 1220, 1241.]
