1. the method making calcium fluoride and sulfuric acid reaction and manufacture fluohydric acid gas, it is characterised in that including:

  • (a) with the amount that mol ratio is 0.9~

    1.1 of sulphuric acid/calcium fluoride, by calcium fluoride particles that mean diameter is 1~

    40 μ

    m withSulphuric acid mixes the temperature of 0~

    70 DEG C and reacts, and obtains the operation of solid, shaped reactant mixture;

    WithB the temperature that this solid, shaped reactant mixture is heated to 100~

    200 DEG C is made it react by (), generate and obtain in the gas phaseThe operation of fluohydric acid gas,Operation (a) comprises the steps;

    the amount that mol ratio is 0.9~

    1.1 with sulphuric acid/calcium fluoride, is 1~

    40 by mean diameterThe calcium fluoride particles of μ

    m and sulphuric acid carry out raw material the temperature of 0~

    30 DEG C and mix, then, in the temperature mixed higher than this raw material andTemperature heating below 70 DEG C makes it react, and obtains solid, shaped reactant mixture.
