By condensation of 9-[N-(2-naphthyl)formimidoyl]anthracene with methyl ketones under conditions of acid catalysis, 1-R-3-(9-anthryl)benzo[f]quinolines have been obtained. The byproducts of the reaction have been identified: 1-R-3-(9-anthyl)-2-propen-1-ones and N-[1-(p-aminophenyl)-3-(9-anthryl)-2-propen-1-ylidene]-2-naphthylamines. The spectral and luminenscence properties of these compounds have been examined critically.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1536–1541, November, 1985. 相似文献

Human insulin in zinc suspension was used as a model protein to test the effect of shear on the settling rate of proteins,
a possible inference for protein denaturation. The rate of settling was determined directly in a spectropho-tometer. Shear
effects are important in retaining the activity of proteins and are present in bubble, foam, and droplet protein fractionation
processes. A sim pletest, such as that conducted here, mayeven be useful for monitoring changes in protein structure caused
by commercial shipping of the protein. The settling ratefor insulin was continously monitored in theoriginal bottle by spectrophotometric
absorbance changes as a function of time. A settling curve was determined following each shear experiment, which included
shaking the “worked” insulin solution in a vortex mixer for different lengths of time. It was determined, when comparing long
shaking times with short ones, that the initial settling rate was less for the long-term shaking of the insulin samples and
greater for the short-term shaking. The secondary effects of light and heat, along with shaking, a pparently did not produce
differences from shaking alone. 相似文献

The temporal evolution of the opacity of an iron plasma at high temperature (30-350 eV) and high density (0.001-0.2 g cm-3) has been measured using a nickel-like silver x-ray laser at 13.9 nm. The hot dense iron plasma was created in a thin (50 nm) iron layer buried 80 nm below the surface in a plastic target that was heated using a separate 80 ps pulse of 6-9 J, focused to a 100 microm diameter spot. The experimental opacities are compared with opacities evaluated from plasma conditions predicted using a fluid and atomic physics code. 相似文献
