And the article contained the following:
The present study is intended to adopt a facile method for preparing a sulfonated green carbon catalyst from date pits biomass. Catalyst synthesis involves in situ carbonization and sulfonation and it has been characterized by following techniques such as XRD, SEM, EDX, TEM, FTIR, TGA, and BET. Surface and internal morphol. results exhibited that the synthesized sulfonated carbon material possesses a mesoporous structure, while activated carbon possesses a microporous structure. Furthermore, the Fourier transform IR (FTIR) spectra confirmed the presence of acidic groups (-OH, -COOH, and -SO3H) in synthesized sulfonated carbon material. Sulfonated carbon material exhibited high acidity (4.7 mmol/g) and good thermal stability. The application of this catalyst for the tertiary butylation of phenol without using any solvent has been investigated. The phenol alkylation reaction showed maximum conversion at reaction condition: temperature (140°C) with 2 bar (nitrogen gas) pressure with maximum phenol conversion 79.27 wt%, with 68.01% selectivity towards 4TBP+2,4TBP, which is used as an intermediate in antioxidants. The catalyst exhibits comparable catalytic performance up to five reaction cycles. Thus it can be concluded that waste date pits can be successfully employed for green catalyst synthesis and used for reactions involving large mols. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Safety of 2,4-Di-tert-butylphenol
