Description

Open Data for the full paper entitled "A one-pot route to tunable sugar-derived sulfonated carbon catalysts for sustainable production of biodiesel by fatty acid esterification" published by S.L. Rokhum et al. in Renewable Energy, 2022, 184, 908-919.

In this work, synthetic data report the synthesis and regeneration/reuse of a glucose-derived sulfonated carbon catalyst for biodiesel synthesis. The following supporting data are deposited: Solid-state magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy data. Spectra were measured for 4 fresh catalyst samples (HTC3, HTC9, HTC10, HTC11) and also for D-(+)-glucose (from Fisher scientific, 99.99% purity). Separately, data were also obtained for fresh, used (5 times) catalyst HTC3 and its regenerated (re-sulfonated) derivative HTC3-R (see main manuscript for synthetic protocols). All NMR spectroscopic data were obtained using a Bruker AVANCE 400 MHz instrument equipped with a 9.4 T magnet and a 4 mm double resonance probe. Data are presented for 1H and 1H–13C cross-polarization (CP) experiments. These were performed using 10 kHz MAS, and applying 100 kHz 1H broadband SPINAL64, 4 ms CP contact time (using 75 kHz ramped 1H and 65 kHz square 13C contact pulses). A 2 s recycle delay was employed. Chemical shifts were referenced externally using the methyl signal of trimethylsilylpropanoic acid at 0.0 ppm (1H) and the methylene signal of glycine at 43.1 ppm (13C). Experiments were conducted using Bruker TopSpin 2.1 and the raw output can be processed and viewed using Bruker TopSpin, Mestrelab MNova or similar software.
