30 thg 7, 2021 · Under optimized conditions, the bio-transformation of 400 mM citral caused nearly complete conversion (>99.5%) to enantio-pure (S)-citronellol within 36 h, demonstrating …
1 thg 4, 2016 · The citral conversion (99%) was attained with 95% selectivity to citronellal in a ratio of catalyst to citral (1:6) under 110 psi H2 pressure at 90 °C for 90 min using 12% Ni–HT-530.
20 thg 2, 2003 · Selective hydrogenation of citral to citronellol has been investigated over Ni supported catalysts. The aim was to compare different support materials and catalyst …
22 thg 12, 2020 · In this paper, a waste fluid catalytic cracking (FCC) catalyst is used as a carrier to prepare a supported non-noble metal nickel catalyst (Ni/wFCC), which is applied to the …
of citral to citronellal in the presence of Ni-Cr2O3 catalyst were studied. The effect of hydrogen pressure on citral hydrogenation was studied over the catalyst Ni-Cr2O3 (0.5 g)
20 thg 4, 2022 · The synthesis of citronellal, an added-value chemical for perfumery, was performed through selective and green hydrogenation of citral into citronellal in water.
15 thg 6, 2025 · Two prominent methods are employed, using myrcene (developed by Japan’s Takasago company) and citral (developed by Germany’s BASF company) as raw materials, …
Thus, industrially important products like citronellal (2), geraniol (E - 3), nerol (Z - 3), or citronellol (5) are available from 1 by addition of hydrogen to one of the unsaturated sites.
Both citronellal and citronellol can be prepared separately or in admixture by the process of the invention, starting from citral, and can be obtained in high purity and substantially without...
To access the key intermediate (R)-citronellal used in current major industrial production routes, we established a one-pot bienzymatic cascade from inexpensive geraniol, overcoming the …
