Abstract
PURPOSE: To enable the safe storage and transportation of hydrofluoric acid, by reacting hydrofluoric acid with pyridine to obtain a pyridine.hydrofluoric acid complex containing high molar ratio of hydrofluoric acid, and distilling the complex at the desired time and place to obtain hydrofluoric acid.
CONSTITUTION: Hydrofluoric acid (HF) is made to react with pyridine (Py) to obtain Py.(HF)n complex (n≥3), or Py.(HCl) complex is made to react with ≥8 equivalent of HF to obtain Py.(HF)m complex (m≥8). The complex thus obtained has low HF vapor pressure and high safety, and can be stored or transported to anywhere in a conventional container made of, e.g. PE. For obtaining HF, most part of the HF can be released by the vacuum distillation of the complex, according to the formula. When the valve of (n) is large, the utilization ratio of Py becomes sufficiently high, and the resultant Py.(HF)3 can be recycled and reused as the raw material of Py.(HF)n. Or the residual 3mol of HF can be utilized by reacting the Py.(HF)3 with HCl.
