你说的这个在什么状态下是这个情况，应该温度在零下40度以上，零上40度以下都应该是不变的
The present invention discloses a method and apparatus for the electrolytic separation of fluorine from a gas mixture. 还记载了从含氟/氟化合物的固体,气体或液体中生成氟的方法和装置. Also describes a method and apparatus for generating fluorine from the solid, liquid or gaseous fluorine / fluoride...
Adding chemistry's most electronegative atom to porous polymer networks may lead to gas-specific filters capable of flexible ‘breathing’. The tunable activity of metal–organic frameworks towards specific guest molecules, such as drugs or pollutants, has led to a flurry of recent research reports....
The reaction with hydrogen can occur at extremely low temperatures, using liquid hydrogen and solid fluorine. It is so reactive that metals, water, as well as most other substances, burn with a bright flame in a jet of fluorine gas. In moist air, it reacts with water to form the also ...
The halogens are a group of chemical elements that includes fluorine, chlorine, bromine, iodine, and astatine. ... All of the halogens exist as diatomic molecules when pure elements. Fluorine and chlorine aregases. Bromine is one of only two liquid elements, and iodine is a solid. ...

The impurities include, for example, water in gaseous or liquid form, oxygen or oxides. Water in gaseous or liquid form or oxygen may be removed by allowing platinum black to stand in a low-pressure chamber. It is also effective to flow a purge gas. The degasification is carried out more...
and insulating members such as insulating gaskets and insulating packings. The sealing members are members to be used for preventing leakage of a liquid or a gas, or penetration of a liquid or a gas from the outside. The insulating members are members to be used for insulating electricity. ...

When the polymer obtained by drying is a solid, it is pulverized in a mortar, and in the case of a liquid, IR-ATR spectrum is measured in a liquid state. In the case of a solid, if a degree of drying is insufficient, it is hardly pulverized, and therefore, it is recommendable to...
