Reference of cis-4-Aminocyclohexane carboxylic acid. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: cis-4-Aminocyclohexane carboxylic acid, is researched, Molecular C7H13NO2, CAS is 3685-23-2, about Hydrogenation of ammonium p-aminobenzoate on ruthenium and rhodium catalysts. Author is Freidlin, L. Kh.; Litvin, E. F.; Oparina, G. K.; Gurskii, R. N.; Istratova, R. V.; Videneeva, L. V..
The rate of hydrogenation of aqueous p-H2NC6H4CO2- NH4+ in the presence of 10% Rh/C exceeded that in the presence of 10% Ru/C or 9.5% Ru-0.5% Pd/C, and increased linearly with the pressure at 40-100 atm; the apparent activitation energy at 80-150° was 9-10 kcal/mole. The combined yield of cis- (I) and trans-4-amino-1-cyclohexanecarboxylic acid (II) was 92-3% at 80° and 80 atm, but decreased with increasing temperature owing to thermal decomposition; the II-I ratio was independent of pressure, but increased with the hydrogenation temperature, owing to cis-trans isomerization.
There is still a lot of research devoted to this compound(SMILES：N[C@H]1CC[C@H](CC1)C(O)=O)Reference of cis-4-Aminocyclohexane carboxylic acid, and with the development of science, more effects of this compound(3685-23-2) can be discovered.
