At temperatures above 300☏ (149☌) a chlorine/steel fire can result. Steel is the most common material used in dry chlorine service. Care should be taken to make sure titanium materials are not used in dry chlorine service. In the presence of dry chlorine, titanium is flammable. Two of the more common metals are titanium and steel. The reaction rate of dry chlorine with most metals increases rapidly above a temperature which is characteristic for the metal. However the resulting water phase is extremely corrosive, see Reactions with Metals below. See Pamphlet 121 for more information.Ĭhlorine usually forms compounds with a valence of -1 but it can combine with a valence of +1, +2, +3, +4, +5, or +7.Ĭhlorine is only slightly soluble in water (0.3% to 0.7%) depending on the water temperature. The reaction is initiated very easily much the same way as hydrogen and oxygen. Chlorine reacts explosively with hydrogen in a range of 4% to 93% hydrogen. An important specific compound of concern is hydrogen. Many organic chemicals react readily with chlorine, sometimes violently. Many materials that burn in oxygen (air) atmospheres will also burn in chlorine atmospheres. Chlorine will support combustion under certain conditions. The measure of internal molecular friction when chlorine molecules are in motionĬhlorine is neither explosive nor flammable. The absolute pressure of chlorine gas above liquid chlorine when they are in equilibrium The volume of a unit mass of chlorine at specified conditions of temperature and pressure. Ratio of gas specific heat at constant pressure to gas specific heat at constant volume The heat required to raise the temperature of a unit weight of chlorine one degree. The ratio of the density of saturated liquid chlorine to the density of water at its maximum density - 39°(4☌)

(Note: The density of air, free of moisture at the same conditions is 1.2929 kg/m 3) The ratio of the density of chlorine gas at standard conditions to the density of air under the same conditions: The weight of chlorine which can be dissolved in a given amount of water at a given temperature when the total vapor pressure of chlorine and the water equals a designated value. The temperature at which solid chlorine melts or liquid chlorine solidifies The weight of one volume of liquid chlorine equals the weight of 456.5 volumes of chlorine gas. The heat required to evaporate a unit weight of chlorine The mass of a unit volume of chlorine at specified conditions of temperature and pressure. The volume of a unit mass of chlorine at the critical pressure and temperature The temperature above which chlorine exists only as a gas no matter how great the pressure The vapor pressure of liquid chloride at the critical temperature The mass of a unit volume of chlorine at the critical pressure and temperature The temperature at which liquid chlorine vaporizes The data on physical properties of chlorine as determined by different investigators show some variations. The gas is greenish yellow in color and the liquid is clear amber. Chlorine has a characteristic penetrating and irritating odor.
