MetadataShow full item record
A surfactant tert-butyl galactoside has been synthesized from galactose and tert-butanol in asetalization reaction. Acetalization of galactoside with tert-butanol in petroleum ether as a solvent using p-TSA as catalyst gave tert-butyl galactoside. The product was characterized by analysis spectroscopy FT-IR, 1H-NMR and the measurement of surface tesion. The compound of tert-butyl galactoside was a surfactant with critical micelle concentration (CMC) was 0,02%and hydrophilic-lypophilic balance (HLB) value 3,93.
