HPLC of Formula: 591-12-8. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-Methylfuran-2(3H)-one, is researched, Molecular C5H6O2, CAS is 591-12-8, about Carbon nanotube/PTFE as a hybrid platform for lipase B from Candida antarctica in transformation of α-angelica lactone into alkyl levulinates. Author is Szelwicka, Anna; Kolanowska, Anna; Latos, Piotr; Jurczyk, Sebastian; Boncel, Slawomir; Chrobok, Anna.

In this work an enzymic method for the synthesis of alkyl levulinates from α-angelica lactone has been reported for the first time. Lipase B from Candida antarctica was immobilized via interfacial activation on the surface of a hybrid support, consisting of com. available multi-walled carbon nanotubes (MWCNTs) and polytetrafluoroethylene (PTFE). Among the biocatalysts with various contents of PTFE in the support, the CALB/MWCNT-PTFE (0.10 wt%) biocatalyst with 22.5 wt% CALB loading was determined as the most active one in the model synthesis of the Bu levulinate in toluene. n-Bu levulinate was obtained quantitively after 120 min of the reaction under the selected reaction conditions (2-fold molar excess of n-butanol, 0.150 g of biocatalyst per 1 mmol of α-angelica lactone, 20°C). The yield of Bu levulinate was found to be higher than that in the presence of accurate amounts of sulfuric acid or Novozyme-435. Addnl., the unique stability of the developed biocatalyst was demonstrated over 6 reaction cycles at 20°C. The biocatalyst remained stable over 3 reaction cycles at 60°C as well. The essence of the proposed approach lies in the possibility to overcome the equilibrium limitations occurring in the conventional Fisher esterification. The activity of the elaborated hybrid biocatalyst in the reactions non-specific for lipases is a clear proof of the versatility of the novel system.
