The effect of the temperature (T = 275 K, 290 K y 303 K) and the catalyst [RhCl((NH2(CH2)12CH3)3] in homogeneous and heterogeneous phase (support: RX3 a carbonaceus material purchased from Norit) was analyzed on (Z)/(E) ratio for the 3-hexyne semi-hydrogenation in a batch process at mild operational conditions. The Lindar catalyst was used as a reference system. Centesimal Composition, XPS, FTIR, Gas Chromatography and Atomic Absorption were employed to characterize the system at the different stages of the research. The analisys of the obtained results indicates that the best option, to favor the desired isomer ((Z)) is given by the anchored complex at 303 K. This situation can be explained due to electronic and geometrical effect at a nanoscopic level.
