New discoveries in chemical research and development in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 2210-74-4, Name is 1-(2-Methoxyphenoxy)-2,3-epoxypropane, molecular formula is C10H12O3. In an article, author is Sokolov, V. I.,once mentioned of 2210-74-4, Safety of 1-(2-Methoxyphenoxy)-2,3-epoxypropane.
New copolymers of perfluoro-2-ethyl-2-methyl-1,3-dioxole and perfluorovinyl ether with low non-monotonic refractive index
Copolymers of perfluoro-2-ethyl-2-methyl-1,3-dioxole and perfluoro-5-methyl-3,6-dioxanon-1-ene were synthesized using high-pressure technique without initiators. Copolymers have molecular weight of (1.2-4) center dot 10(4) and possess high optical transparency in the telecommunication C-band region of 1530-1565 nm. Refractive index n of copolymers as a function of ether mol.% in the macromolecule x was investigated. It is established that the curve n(x) is non-monotonic, the difference of refractive indices of copolymers with various x differs by n = 0.015. The synthesized materials are amorphous, capable of film formation, and can be used for the fabrication of optical fibers and integrated optical waveguides with numerical aperture NA from 0.13 to 0.2, with waveguiding core and cladding made of perfluorinated materials.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2210-74-4, in my other articles.
