Sodium tert-butoxide 865-48-5 Usage Reliable quality 865-48-5 in bulk supply
Sodium tert-butoxide (STB), which can exist stably in aprotic electrolyte to obtain high cycle stability, is used as a strong base and a non-nucleophilic base. It is an organosilicon compound that is used to reduce the reactivity of halides, such as trifluoroacetic acid.
Flammability and Explosibility
Highlyflammable
Purification Methods
Its solubility in tert-BuOH is 0.208M at 30.2o and 0.382M at 60o, and it is quite soluble in tetrahydrofuran (32g/100g). It should not be used if it has a brown colour.

Sodium tert-butoxide as stable electrode material in aprotic electrolyte for high cycle stability organic sodium-ion batteries
T Huang, R Zheng, H Chang, D Ma, H Niu
Journal of Power Sources, 2022
We report a new organic active unit sodium tert-butoxide (STB), which can exist stably in aprotic electrolyte to obtain high cycle stability. As the electrode of rechargeable batteries, the STB exhibits a capacity of 206 mAhg−1 at 35 mAg−1, 2.4 V. The battery runs more than 5000 cycles at 210 mAg−1, 135 mAhg−1, no capacity attenuation.
