리튬메톡사이드 C화학적 특성, 용도, 생산
화학적 성질
Lithium Methoxide [865-34-9], LiOCH3, Mr 37.98, is a white solid that is soluble in methanol but virtually insoluble in aprotic organic solvents. It is commercially available as a 99 % fine crystalline solid and as 10 % solution in methanol. It can be used as base, especially as catalyst for transesterification reactions.
용도
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.
Purification Methods
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.]
