Tert-Butyl Alcohol (TBA)
CAS No.: 75-65-0
Molecular Weight: 74.04 Molecular Formula: C4H10O
TBA is a clear, noncorrosive liquid. It is miscible with water as well as most common organic solvents and forms azeotrope. The sterically hindered tertiary butyl group imparts stability compare to primary and secondary alcohols. In result, the solubility and oxidative stability characteristics provide many industrial applications as a reaction and process solvent and chemical intermediate.

|Main Content (TBA) (m/m)||≥99.5%|
|Boiling range||Initial boiling point||≥81.5℃|
|Free acid as achtic acid (m/m)||≤0.003%|
|Non-volatile matter (m/m)||≤0.002%|
Note: The temperature correction factor of TBA density is 0.00091(densitometer method), range of application temperature 24.5°C-30°C.
TBA is used as a non-reactive solvent for chemical reactions, a non-surfactant compatibilizer for many solvent blends, and a non-corrosive solvent. It is used in free radical polymerizations to dissolve monomers. TBA is a main raw material of tert-butyl functional group in organic synthesis. TBA is used as a coupling aid for formulating pesticides and fertilizers in aqueous solutions without generating an emulsion. It was used as a fuel additive for high octane component to replace tetraethyl lead. TBA is also used as a reaction solvent as well as an intermediate for the product of organic peroxides, metal alkoxides. Tert-butyl group is readily cleaved under strongly acidic conditions. TBA is a source to produce alkylated aromatic and nitrogen compounds in mid acidic conditions. Dehydration reaction of TBA yields isobutylene which is the main raw material of MTBE, the mostly used fuel oxygenates.
