Chemical Structure
Description
Based on its molecular formula C16H36O4Si, 4766-57-8 Butyl silicate ((BuO)4Si) Butyl silicate ((C4H9O)4Si) NSC-89762 NSC89762 Silane, tetrabutoxy- Silicic acid (H4SiO4), tetrabutyl ester Silicon tetrabutoxide Tetra-n-butoxysilane Tetrabutoxysilane Tetrabutyl orthosilicate Tetrabutyl silicate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 320.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
