Can someone describe the chemical reaction that makes C6H5NO2 into C6H5NH2? or turns Nitrobenzene into aniline? L

No, but as long as we are on the subject of chemistry... Does anyone know a chemcial reaction in daily life that would clearly demonstarte the law of conservation of matter? T

Aniline is manufactured by catalytic reduction of nitrobenzene with iron filings from http://www.safety.ubc.ca/environmental/ww/facts/FactS3.htm T

ltk007, place a lit candle under a large glass bowl and put everything on a scale. The chemical reaction is wax + oxygen from air = CO2 + water, the candle eventually suffocates, you get some smoke but the mass remains unchanged as the scale will show. V

Is this what you want? C6H5NO2 mixed with H ions (like in an acid) and Pt, Ni, or Zn as a catalyst will yield H6C5NH2. Other possible catalysts are Sn, HCl and heat OR Fe and HCl. I'd recommend a good organic chemistry course if you're trying to brush up on your nitro to amine reactions. 🙂 C

heh, im only 15 in highschool i have chem honors, and i have a presentation to do on nitrobenzene, if you can explain that in simple mans term that would help! thanks guys N

C6H5NO2 can be reacted over Fe, dilute HCl, and heat to form Anilinium chloride, C6H5NH3+CL-, and then with Na2C03 to form C6H5NH2. Hydrogenation of a nitro compund to an amine takes place smoothly when a solution of the nitro compound in alcohol is shaken with finely divided nickel or platinum under hydrogen gas. Examples: C6H5NO2 --(H2, Pt)--> C6H5NH2 Chemical reduction in the laboratory is most often carried out by adding hydrochloric acid to a mixture of the nitro compound and a metal, usually granulated tin or iron. In the acidic solution, the amine is obtained as its salt,; the free amine is liberated by the addition of base, and is steam-distilled from the reaction mixture. C6H5NO2--(Sn, HCl, heat)--> (C6H5NH3+)2 SNCl6 2- --(OH-)--> C6H5NH2 + SnO3 2- . R

H2 using Pd/C as catalyst J

itk007, actually, that "law" is false. anytime you have an exothermic reaction, you're changing mass into energy. thus chemical reactions give you the least amount of mass/energy conversion whereas matter/antimatter give you the most. R

<<actually, that &quot;law&quot; is false. anytime you have an exothermic reaction, you're changing mass into energy. thus chemical reactions give you the least amount of mass/energy conversion whereas matter/antimatter give you the most.>> Umm dumbass, anytime you convert mass to energy it's called a NUCLEAR reaction. Exothermic means release of heat, and is in reference to the release of CHEMICAL energy (ever wondered why batteries get hot when they are used?) Is this an example of the US education system... my I didn't think it had gotten that bad... C

whoa this is still extreamly confusing! can someone explain even simpler>? N

I doubt it can get much simpler than visgf posted. My post was a direct quote from my organic chem text. You must log in or register to reply here. Share: Facebook X Bluesky LinkedIn Reddit Tumblr WhatsApp Email Share Link
