Perfluorooctane
全氟辛烷（C8F18）熔点为-25℃，沸点为103℃，不燃，无毒，化学稳定性高，为无色透明略带煤油气味的液体。全氟辛烷不溶于水、乙醇、醋酸、甲醛，但可溶解于乙醚、丙酮、二氯甲烷、氯仿及氟氯烷烃。全氟辛烷具有较低的表面张力和较高的介电强度，耐热性非常好，分解温度超过800℃。全氟辛烷可以溶解大量的氧气和二氧化碳，可与其它氟碳化合物配伍用做人工血液和离体后器官保存液等。
Perfluorooctane (C8F18) is a kind of colorless, transparent and slight kerosene-scented liquid with melting point of -25℃, boiling point of 103℃, it is non-flammable, non-toxic with high chemical stability. Perfluorooctane is insoluble in water, ethanol, acetic acid and formaldehyde, but it's soluble in ether, acetone, dichloromethane, chloroform and chlorofluorocarbons. Decomposition temperature of perfluorooctane with low surface tension, high dielectric strength and good heat resistance is more than 800℃. Perfluorooctane can dissolve a large amount of oxygen and carbon dioxide, and can be used as artificial blood and preserving fluid of organ in combination with other fluorocarbons.
