摘要
An object of the present invention is to provide a novel azeoropic or azeotrope-like composition that is effective for the separation of HF from 1,1,2-trichloroethane (HCC-140), trans-1,2-dichloroethylene (HCO-1130(E)), or cis-1,2-dichloroethylene (HCO-1130(Z)). The object can be achieved by an azeotropic or azeotrope-like composition comprising HCC-140, HCO-1130(E), or HCO-1130(Z), and hydrogen fluoride.
