A fundamental and important property of polytetrafluoroethylene (PTFE) and other fluoropolymers is their resistance to organic and inorganic chemicals. Chemical properties of PTFE are not affected by fabrication conditions. Another aspect of the interaction of this plastic with chemicals is permeation. ...
Incompatible with water, many metals, fluorine, acids, variety of organic materials including acids, alcohols and reducing agents. Reaction with water is violent and yields toxic gas. CAS 数据库 :7719-12-2(CAS DataBase Reference) NIST化学物质信息 :Phosphorus trichloride(7719-12-2) EPA化学物质...
A second chemical property of alkanes is halogenation. Halogenation is a chemical reaction used to add a halogen to a compound. Halogens consist of five elements that are chemically related to one another: fluorine, chlorine, bromine, iodine, and astatine. Lesson...

摘要: Some physicochemical properties of synthesized graft copolymers of crude skin and polyacrylic acid are determined. The dependence of molecular weight, solubility, density and thermal properties of copolymers on the ratio of components and synthesis conditions was established.关键词:...

Fluorine changes from a gas to a liquid at a temperature of -188.13°C (-306.5°F) and from a liquid to a solid at -219.61°C (-363.30°F). Fluorine has a strong and characteristic odor that can be detected in very small amounts, as low as 20 parts per billion. This property ...

However, as the applied periodic boundary conditions prohibited a charged surface, each fluorine vacancy instead produced a nominal M(II) center. The most stable and abundant surface of (010) forms a very flat surface of an eight-fold coordinated M(III). The second most abundant surfaces are...
For example, cesium and fluorine react to form CsF, which contains Cs+ and F− ions. When nonmetal atoms with differing electronegativities react, they form molecules with polar covalent bonds.Another important atomic property is atomic size. The sizes of atoms vary; atoms generally tend to ...
