Reference of 29841-69-8, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 29841-69-8, Name is (1S,2S)-(-)-1,2-Diphenylethylenediamine, molecular formula is C14H16N2. In a Article，once mentioned of 29841-69-8
An azo chromophore molecular S(-)-1,2-bis(4-azophenyl-4-nitro)-ethylenediamine (OABANEDA) was synthesized with 4-nitroaniline and S(-)-1,2-diphenyl ethylenediamine by diazo-coupling reaction. The azo polyurethane-urea (OAAPUU) was obtained from OABANEDA, polyether diol (NJ-210) and isophorone diisocyanate (IPDI). The structure of OAAPUU was characterized by the Fourier transform infrared and UV-visible spectroscopy. The physical and mechanical properties of OAAPUU were investigated. The refractive index (n) and transmission loss of OAAPUU film were measured at different temperatures and different laser wavelengths (532 nm, 650 nm and 850 nm) by an attenuated total reflection (ATR) technique and CCD digital imaging devices. A Y-branch and Mach-Zehnder interferometer (MZI-type) switches based on thermo-optic effect of OAAPUU film were designed and simulated. The result showed that the power consumption of the Y-branch switch and the MZI-type switch could be only 0.52 mW and 1 mW, while the response times of the two types switches reach about 0.2 ms and 0.01 ms, respectively.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Reference of 29841-69-8, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 29841-69-8, in my other articles.
