Yield:620-92-8 97.1%
Reaction Conditions:
with MIL-101(Cr/Al)A-f at 60; for 0.5 h;Kinetics;Reagent/catalyst;
Steps:
Hydroxyalkylation of phenol with formaldehyde to bisphenol F wascarried out in reactor with magnetic stirring. Typical experimentalprocesses were summarized as follows: 0.465 g (5.7 mmol) of formaldehydesolution, 8.12 g of phenol and 0.12 g of catalyst were addedinto the reactor and the reaction mixture was heated to the desiredtemperature. After a certain time interval, 0.03 g of the suspension wastaken out and then diluted with 10 mL of methanol. The composition ofthe product was confirmed by HPLC with a Shimadzu LC-20AT systemconnected with a SPD-20A UV/Vis detector and a Phenomenex LunaC18 column (250×4.6 mm, 5 mm); A mixture of methanol and waterwith 65:35 v/v was used as the mobile phase with a constant flow rateof 0.6 mL/min. The injective volume of the sample was 100 μL.
