     one
    This invention relates to chemical technology, in particular to the selection of hydrogen fluoride and boron trifluoride from complexes with orthobenzoyl benzoic acid (OBB-acid).
    The purpose of the invention is to increase the yield of hydrogen fluoride and boron trifluoride.
    Note 1. 1 mol of phthalic anhydride to L mol of benzene is mixed with 10 mol of hydrogen fluoride and 10 mol of boron trifluoride.
    After partial degassing of boron trifluoride at 40 C, a solution of the complex OBV-acid is obtained, containing 203.3 g of OBB-acid, 306.7 BF, 200 g of HF and 22.7 g of impurities.
    Distillation is carried out in a stainless steel column with an internal diameter of 38 nm containing a packing. The temperature in the column is 41 C, the pressure is atmospheric.
    First, within 28 minutes, 110 g of a solution of the complex of O.BB-acid are supplied, then reflux of methylene chloride is supplied for 20 minutes.





    Gaseous HF and BF are collected in the annual part of the column.
    0.5 g of sediment containing 0.24 g of BF hydrate and 0.2 g of N are collected in a decanter installed in the head of the column.

    Production and printing company, Uzhgorod, Project St., 4,.
    BF, 33.3 g of OBB-acid containing 28.6 g of the basic substance, 0.43 g of BF, and 0.1 g of HF are obtained by distillation. .
    Yield,%: acid 93,8j HF-99,6; 99.0.
    Example 2. The process is carried out at 8 Jt ° C according to Example 1, however, 1,2-dichloroethane is used as the halogen-containing aliphatic hydrocarbon.
    The evaporation rate of 1,2-dichloroethane is 4.22 kg / h. 110 g of the solution of the OBB-acid complex and then the phlegm G, 2-dichloroethane are introduced over 22 mi.
    The evaporation rate of 1,2-dichloroethane is 4.22 kg / h. Obtain 32 g of OBB-acid containing 28.0 g of the basic substance, 0.33 T BF and 0.1 g of HF.
    Yield,%: OBB-acid 92-, BF - 99.3; HF - 99.6.
