Yellow to orange yellow crystalline powder, micro-with special
smell, bitter taste. There are three different water solubility of
the crystalline form. Drying time is not affected by scattered
light, but in alkaline solution easily lights the impact of
deterioration. In secret to the stability of inorganic acid, 278 ~
279 ℃when the decomposition (about 240 ℃when the mere mention of
the deep). 1g products 3000 ~ 15000ml soluble in water, saturated
aqueous solution of pH about 6, in aqueous solution and
significantly yellow green fluorescence. At 27.5 ℃Solubility
ethanol for 0.0045g/100ml. Soluble in dilute alkali
(decomposition). Micro-soluble in cyclohexanol, amyl acetate,
benzyl alcohol and phenol, insoluble in ether, chloroform, acetone
and benzene. Specific rotation [α] D25 -112 ° ~ -122 ° (50mg
dissolved in 2ml 0.1mol / L ethanol solution of sodium hydroxide,
diluted with water to 10ml). Maximum absorption wavelength of 220 ~
225,266,371,444,475 nm. Micro-drug, half lethal dose (rat,
oral)> 10g/kg.
Acrylamide gel polymerization of photo-catalyst. Preparation of
