Popis: Sodium carbonate added during citral hydrogenation to citronellol on Ni−Cr2O3 in C2−C5 alcohols increases the citronellol yield to 95%. According to microcalorimetric measurements, the conclusion is drawn that sodium adsorbs on the surface of metallic nickel, thus influencing the adsorbability with respect to various unsaturated groups and the selectivity. A correlation between hydrogen solubility in the alcohol solvent and the attainment of zero order with respect to hydrogen in citral hydrogenation to citronellol in the pressure range of 2–10 MPa is reported.
