四氟化碳，又称为四氟甲烷、Freon-14及R 14，是一种卤代烃（化学式：CF4）。它既可以被视为一种卤代烃、卤代甲烷、全氟化碳，也可以被视为一种无机化合物。

零下198 °C时，四氟化碳具有单斜的结构，晶格常数为a = 8.597, b= 4.433, c = 8.381 (.10-1 nm), β = 118.73° 。
四氟化碳是一种造成温室效应的气体。它非常稳定，可以长时间停留在大气层中，是一种非常强大的温室气体。它在大气中的寿命约为50,000年，全球增温(全球暖化)系数是6,500（二氧化碳的系数是1）。虽然结构与氟氯烃相似，但四氟化碳不会破坏臭氧层。这是因为导致臭氧层破坏的是氟氯烃中的氯原子，它被紫外线辐射击中时会分离。碳-氟键比较强，因此分离的可能性比较低。

滕州市浩瀚色谱仪器技术服务有限公司，与时俱进，以科学发展观为指导，在王晓莹经理的带领下，依托翔鹰分析技术研究所，色谱工程研究所和分析与测试中心3个科研单位，研发出HH-CF4I四氟化碳分析专用填充柱，测定了CF4，O2，N2含量，结果满意。



Carbon tetrafluoride, also known as tetrafluoromethane, Freon-14 and R 14, is a halogenated hydrocarbon (chemical formula: CF4). It can be regarded as a halogenated hydrocarbon, halogenated methane, perfluorocarbon, can also be regarded as an inorganic compound.
At minus 198 ° C, carbon tetrafluoride has a monoclinic structure with lattice constants a = 8.597, b = 4.433, c = 8.381 (.10-1 nm), and β = 118.73 °.
Carbon tetrafluoride is a greenhouse gas. It is very stable, can stay in the atmosphere for a long time, is a very strong greenhouse gas. Its life in the atmosphere is about 50,000 years, and the global warming (global warming) coefficient is 6,500 (the coefficient of carbon dioxide is 1). Although the structure is similar to HCFCs, carbon tetrafluoride does not destroy the ozone layer. This is because the ozone layer destroys the chlorine atom in the HCFC, which is separated when it is hit by ultraviolet radiation. Carbon-fluorine bond is relatively strong, so the possibility of separation is relatively low.

Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., advancing with the times to the scientific concept of development as a guide, under the leadership of Wang Xiaoying manager, relying on Xiangying Institute of Analytical Technology, Institute of Chromatography and Analysis and Testing Center 3 scientific research units , Developed HH-CF4I carbon tetrafluoride analysis dedicated packed column, measured the CF4, O2, N2 content, the results were satisfactory.
