Synthetic Route of 18959-30-3, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 18959-30-3, 4,5-Difluorophthalic Anhydride, introducing its new discovery.
A synthetic route is described to a new monomer, N-(2-biphenylenyl)-4-[2?-phenylethynyl]phthalimide (BPP), which contains both phenylethynyl and biphenylene reactive functional groups. The monomer can be made either from N-(2-biphenylene)acetamide or 2-aminobiphenylene, by reaction with the phenylethynyl-containing anhydride. The monomer was characterised fully and the thermal cure of the material was studied by infrared (IR) spectroscopy and differential scanning calorimetry (DSC). The IR spectra showed that the phenylethynyl group reacted completely within 1 h at 370C. DSC showed the polymerisation exotherm of BPP centred at 379C, lower than two NASA-developed phenylethynyl-terminated imide (PETI) resins. In comparison with the PETI systems, the Tg of cured BPP was ca. 100 C higher, making it a candidate for possible high temperature applications.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Synthetic Route of 18959-30-3. In my other articles, you can also check out more blogs about 18959-30-3
