The present invention provides a process for preparing 2-chloro-3,3,3-trifluoropropene including subjecting, in the absence of a catalyst, at least one chlorine-containing compound selected from the group consisting of chloropropane represented by formula (1): CClX2CHClCH2Cl, wherein each X is the same or different and each represents Cl or F, chloropropene represented by formula (2): CClY2CCl=CH2, wherein each Y is the same or different and each represents Cl or F, and chloropropene represented by formula (3): CZ2=CClCH2Cl, wherein each Z is the same or different and each represents Cl or F, to a reaction with hydrogen fluoride under heating in a gas phase. According to the present invention, 2-chloro-3,3,3-trifluoropropene (HCFC-1233xf) can be effectively prepared by an easy and economically advantageous process that is suitable for industrial scale production.
