Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 1119-46-6, Name is 5-Chloropentanoic acid, molecular formula is C5H9ClO2, belongs to chlorides-buliding-blocks compound, is a common compound. In a patnet, author is Samanta, Santigopal, once mentioned the new application about 1119-46-6, Quality Control of 5-Chloropentanoic acid.
Hydrogen embrittlement of high strength steels due to the presence of a few ppm of diffusible hydrogen is a serious problem. The present work investigates the use of an amorphous Ni-P coating laid by electroless method over API (American Petroleum Institute) X70 line pipe grade steel for H-barrier applications. It has been shown using Transmission Electron Microscopy (TEM) and X-ray Photo-electron Spectroscopy (XPS) that the coating structure is predominantly amorphous with some nano-crystalline phases. The Ni-P coating displays a slower and delayed H-permeation compared with crystalline Ni-electroplated steel at similar coating thickness levels. Furthermore, potentiodynamic polarization and salt fog exposure tests in NaCl solution showed improved corrosion resistance of Ni-P coating compared with crystalline Ni coating. Excellent resistance to H-permeation as well as corrosion in chloride environment has been attributed to the amorphous structure of the Ni-P coating.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 1119-46-6. The above is the message from the blog manager. Quality Control of 5-Chloropentanoic acid.
