Colorless liquid. The dissolution of hydrogen fluoride in water
accompanied by a rather considerable evolution of heat (59,1 kJ/mol).
Technical hydrofluoric acid usually contains a number of impurities (Fe, Rb, As, silicic fluorine hydrogen acid Н2SiF6, SO2, etc.
For coarse it was distilled in the apparatus of platinum or lead, discarding the first portions of the distillate.
Solution of hydrogen fluoride is used for etching the transparent
silicate glass (for example - inscriptions - glass
cover with paraffin, cutting holes for etching). Matt
etching receive pairs of fluoride.
For the etching of silicon in the semiconductor industry.
In the composition of the etching, etching and polishing mixtures, solutions for
electrochemical machining stainless steel and special alloys.
Getting fluoride, cremetorium and bordereau, organofluorine
compounds, as well as the corresponding acids (kremneftoristogo
acid and borderopacity acid), synthetic lubricating oils and
the plastic.
For dissolution of silicates in various analyses.
In the process of alkilirovanija, as a catalyst in the reaction of isobutane and the olefin.
Hydrofluoric acid is poisonous.
