In the last 30 years, little experimental work has been reported on the critical properties of (halogenated hydrocarbon + hydrocarbon) mixtures. Furthermore, the overall amount of reported critical property data for these types of mixtures is quite small. This work aims to extended the existing data set and presents data on the critical temperatures of (i) 14 different chloroalkane (C-3-C-4) + hydrocarbon mixtures (C-6-C-7) as a function of mole fraction and (ii) 10 different aromatic halocarbons (chlorobenzene, fluorobenzene, 1,2-dichlorbenzene, or 1,3-dichlorobenzene) + alkanes (Cs) as a function of mole fraction. All of the (gas + liquid) critical lines were continuous. Therefore, all mixtures displayed either Type I or Type II behavior.
