nitroaniline การใช้

• With ammonia, one obtains 2-chloro-4-nitroaniline, a precursor to diazo dyes.
• Reduction of 1, 3-dinitrobenzene with sodium sulfide in aqueous solution leads to 3-nitroaniline.
• The addition of one water molecule provokes the hydrolysis of the molecule and the release of p-nitroaniline.
• "' 2-Nitroaniline "'is an ambient temperature and pressure, 2-nitroaniline is an orange solid.
• "' 2-Nitroaniline "'is an ambient temperature and pressure, 2-nitroaniline is an orange solid.
• While N-methyl-p-nitroaniline ( MNA also used in IMX-101 ), and diphenylamine ( DPA ) are more commonly employed.
• These can be calculated from the wavelength shifts of 3 6 different solvatochromic dyes in the solvent, usually including Reichardt's dye, nitroaniline and diethylnitroaniline.
• The direct nitration of aniline with nitric acid and sulfuric acid, according to one source results in a 50 / 50 mixture of para and meta nitroaniline.
• DOI : 10.1002 / prep . 201300069 } } Trace amounts of MNA ( N-methyl-p-nitroaniline ) are included in some formulations to aid in processing.
• In the development of thin layer chromatography plates with diazotized p-nitroaniline spray, cryogenine produces a purple spot ( as does sinicuichine, another biphenylquinolizidine lactone alkaloid found in " Heimia " species ).
• It was never commercialized due to its low solubility in water, particularly under acidic pH ( which limited its use, particularly in soft drinks ) and concerns that it might form the toxic compound 4-nitroaniline.
• In a novel kilogram-scale metal-free Meerwein arylation the diazonium salt is formed from 2-nitroaniline, the alkene isopropenyl acetate is an adduct of propene and acetic acid and the reaction product 2-nitrophenylacetone:
• This led the authors to experiment with the use of a coupling reagent, EEDQ ( N-Ethoxycarbonyl-2-ethoxy-1, 2-dihydroquinoline ), in order to promote the condensation of 2-( 2-diethylaminoethylamino )-5-nitroaniline with 4-ethoxyphenylacetic acid.
• "' 3-Nitroaniline "', also known as'meta'- nitroaniline and " m "-nitroaniline, is a non-volatile stable solid commonly used as a raw material for dyes . 3-Nitroaniline is an aniline carrying a nitro functional group in position 3.
