Provided is a coating film that inhibits the formation of coke in an ethylene dichloride to a vinyl chloride monomer pyrolysis cracker and a method of producing the coating film. The coke formation, which occurs during a pyrolysis reaction, is inhibited by coating a boron compound on a heat-transfer surface of the cracker. As a result, the amount of coke generated when a coke formation-inhibiting material is coated is decreased by 50% or greater than that when the coke formation-inhibiting material is not coated. In this case, however, the ethylene chloride conversion and the selectivity to a vinyl chloride monomer during the pyrolysis reaction are not affected. Accordingly, the efficiency of the pyrolysis cracker can be maximized.
