A process for removing a halogen component from a halogen-containing organic compound, which comprises contacting an organic compound in the liquid state which is produced by using a halogen containing catalyst selected from the group consisting of Friedel-Crafts catalysts and Ziegler catalysts and contains the halogen component derived from said catalyst, with a hydrotalcite compound represented by the formula M1-x2+Mx3+(OH)2+x-nyAyn-.mH2O wherein M2+ represents a divalent metal ion selected from the group consisting of Mg2+, Zn2+, Ca2+, Ni2+, Co2+, Mn2+ and Cu2+, M3+ represents a trivalent metal ion selected from the group consisting of Al3+, Fe3+ and Cr3+, An- represents an anion having a valence of n selected from the group consisting of HCO3-, OH- and CO32-, and x, y and m are each a positive number and satisfy the following conditions 0.1<x<0.5, 0.1<y<0.4, 0</=m<1, under non-aqueous conditions, and separating the treated organic compound from the hydrotalcite compound.
