Deactivation of a 5 wt% Pd/Al 2 O 3 catalyst during hydrogenation of citral (1) to citronellal (2), 3,7-dimethyl-2-octenal (3), and dihydrocitronellal (4) has been studied in a continuous-flow fixed-bed reactor. The reactions were carried out at 40 °C and 190 bar in hexane, “supercritical” CO 2 , or ethane as solvents. ATR-IR spectroscopic analysis of the solid/liquid interphase...
Abstract.Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) was used as a complementary technique to X-ray fluorescence (XRF), for multi-element analysis of geological samples fused with lithium-tetraborate Li2B4O7). Different calibration strategies using external non-matrix matched reference materials were investigated. Various internal standards were tested, including the use...
