How to convert acetone to isopropyl amine

Answers

Answered by aqibkincsem

Acetone --(CH3COCH3) can be converted to Isopropyl alcohol,CH3CH(OH)CH3 ,by adding Hydrogen (H2), which breaks the carbon-oxygen double bond(C=O) and makes one -H and one ----OH bond.

CH3COCH3+H2 = CH3CH(OH)CH3

This alcohol product can be treated with ammonia (NH3) at high temperature to form isopropyl amine, CH3CH(NH2)CH3

CH3CH(OH)CH3+NH3 = CH3CH(NH2)CH3 +H2O

professorchaotp657tz: In theory, acetone can be transformed into isopropylamine as follows via Leuckart Reaction (reductive amination):

CH3C(O)CH3 + 2 HCO2− +NH4 → (CH3)2CHNHCHO + 2 H2O + NH3 + CO2
(CH3)2CHNHCHO + H2O → (CH3)2CHNH2 + HCO2H

professorchaotp657tz: The low b.p. of acetone may be a problem, as the m.p. of ammonium formate is around 120C . But would be much better for smaller operations since hydrogen and ammonia are not used, and ammonium formate is readily available and inexpensive.
