How does chlorine turn into liquid chlorine? How to store it?
To convert chlorine gas into liquid chlorine, three methods are generally used: high temperature and high pressure, low temperature and low pressure, and medium temperature and medium pressure. These methods differ in terms of energy consumption. Liquid chlorine is usually stored in specialized cylinders; if you intend to produce it, it should be used as a raw material. What is available on the market is already in liquid form. It requires close supervision, and obtaining the necessary permits is difficult.
Elemental chlorine is chlorine gas at room temperature, a pale green toxic gas, Cl2, composed of two chlorine atoms. At a pressure of 1.01×105 Pa, when cooled to -34.6°C, it becomes liquid chlorine (also known as chlorine in liquid form). Liquid chlorine continues to cool down to -101°C, turning into solid chlorine. To convert gaseous chlorine into liquid chlorine, cooling is necessary. Common cooling devices include low-temperature and ultra-low-temperature refrigerators (from -10°C to -152°C), negative-pressure air coolers, and freezers (from -4°C to -30°C)
