Analine

Product Information

Traditionally, the weak basicity of aniline is attributed to a combination of inductive effect from the more electronegative sp 2 carbon and resonance effects, as the lone pair on the nitrogen is partially delocalized into the pi system of the benzene ring. (see the picture below): The donation of the nitrogen's lone pair into the ring system increases the electron density around the ring. That makes the ring much more reactive than it is in benzene itself. Exposure of rats to aniline can elicit a response that is toxic to the spleen, including a tumorigenic response. [41] Rats exposed to aniline in drinking water, showed a significant increase in oxidative DNA damage to the spleen, detected as a 2.8-fold increase in 8-hydroxy-2'-deoxyguanosine (8-OHdG) in their DNA. [41] Although the base excision repair pathway was also activated, its activity was not sufficient to prevent the accumulation of 8-OHdG. The accumulation of oxidative DNA damages in the spleen following exposure to aniline may increase mutagenic events that underlie tumorigenesis.

Exposure may also occur by eating food or drinking water contaminated with aniline. However, these amounts would be expected to be very small.

Word History

Because of the nature of this particular acyl group, it is also described as ethanoylation. The hydrogen is being replaced by an ethanoyl group, CH 3CO-. The Chancellor Jeremy Hunt has today (Wednesday 22 November) announced a range of tax, benefits and savings measures. We round up the key announcements and what they mean for you.

It reacts with nitrobenzene to produce phenazine in the Wohl-Aue reaction. Hydrogenation gives cyclohexylamine. Taking bromoethane as a typical halogenoalkane, the reaction with phenylamine happens in the same series of complicated steps as with any other amine. Phenylamine is slightly soluble in water - about 3.6 g (depending on where you get the data from!) of phenylamine will dissolve in 100 g of water at 20°C. Mixtures containing more phenylamine than this separate into two layers, with the phenylamine forming the bottom one. Park SJ, Cochran JR (2009-09-25). Protein Engineering and Design. CRC Press.

Beta-alanine side effects

With phenylamine, the only difference is that it is a much weaker base than ammonia or an amine like ethylamine - for reasons that we will explore later. On heating, the bromoethane and phenylamine react to give a mixture of a salt of a secondary amine and some free secondary amine. In this case, you would first get N-ethylphenylammonium bromide:
