mol-1Al turnover frequency (TOF) of 4-chlorobenzoylchloride is reported for the first time in the benzoylation of chlorobenzene using 4-ClBC as benzoylating agent and zeolite H-beta as the catalyst.doi:10.1023/A:1016771719956C. Venkatesan...
p- Hydroxybenzoic acid (10.0 g, 0.0724 mol), triethy- lamine (16.12 g, 0.159 mol) and 60 mL of distilled tetrahydrofuran were taken into a flask equipped with a thermometer, a dropping funnel and gas inlet and outlet tubes under a slow stream of nitrogen. Ben- zoyl chloride (10.17 g,...
Acid-treated montmorillonites belonging to the K series (supplied by Süd-Chemie) were tested as heterogeneous catalysts for the liquid-phase acylation of 1,3-dihydroxybenzene with benzoic acid; this reaction may represent an environmentally friendly alternative to the use of benzyltrichloride as the...
Benzoyl chlorideLiquid phase benzoylation of diphenyl oxide (DPO) to 4-(benzoyl)-diphenyl oxide ( p-isomer) with benzoyl chloride (BC) has been investigated with 12-tungstophosphoric acid supported on zirconia (TPA/ZrO 2) as the catalyst. Among the catalysts, 15 wt.% TPA/ZrO 2 calcined ...
The liquid phase benzoylation of o -xylene with benzoyl chloride (BOC) over various zeolite catalysts is studied in a batch reactor at atmospheric pressure and 411 K. The results obtained over different zeolite catalysts are compared with the homogeneous Lewis acid catalyst, AlCl 3 and amorphous ...
J. Mol. Sci. 2016, 17, 1412 4 of 12 In the subsequent step, compound 5 having C-4 free hydroxyl group was reacted with benzoyl chloride (1.1 equivalent) in dry pyridine to furnish a white solid, melting points (mp) 115–117 ◦C (Scheme 1). We observed complete disappearance of ...
