    摘要： A process is disclosed for the manufacture of CF3CF═CH2 and CF3CH═CHF. The process involves dehydrofluorinating CF3CHFCH2F in the presence of a dehydrofluorination catalyst to produce a product mixture comprising CF3CF═CH2 and CF3CH═CHF, and recovering said CF3CF═CH2 and CF3CH═CHF from the product mixture. The present invention also provides a composition comprising (a) the Z-isomer of CF3CH═CHF and (b) HF; wherein the HF is present in an effective amount to form an azeotropic combination with the Z—CF3CH═CHF.
