Application


  • Speciation of tin ions in oxide glass containing iron oxide through solvent extraction and inductively coupled plasma atomic emission spectrometry after the decomposition utilizing ascorbic acid.: This study explores the speciation of tin ions in oxide glass, enhanced by hydrofluoric acid in the decomposition process for analytical purposes ( Saijo et al., 2022).


  • Physicochemical and morphological characterization of a glass ceramic treated with different ceramic primers and post-silanization protocols.: This research discusses the use of hydrofluoric acid in preparing glass ceramic surfaces to enhance their physicochemical properties for dental applications ( Moreno et al., 2019).


  • Chemical analysis of acidic silicon etch solutions I. Titrimetric determination of HNO(3), HF, and H(2)SiF(6).: This paper details a method for analyzing hydrofluoric acid concentrations in industrial etching solutions, providing critical insights into its effective use in silicon processing ( Henßge et al., 2007).


  • Structure of a novel phosphoglycolipid from Deinococcus radiodurans.: Hydrofluoric acid was utilized in the extraction processes that led to identifying unique phosphoglycolipids, contributing to biochemical research and applications ( Jürgens et al., 1986).

The carbonium ion has been suggested to be the intermediate in superacid-promoted reactions (SbF(5)-HF) such as hydrogen-deuterium exchange and in the electrophilic C-H cleavage into hydrogen and the carbenium ion. In this study, the superacid-promoted C-H cleavage into hydrogen and

The exothermic F + H(2)O → HF + OH reaction has a decidedly "early" or "reactant-like" barrier. According to a naïve interpretation of the Polanyi's rules, translational energy would be more effective than vibrational energy in promoting such reactions. However
