And the article contained the following:
An efficient alk. catalyst with porous structure (Na-CH3ONa/çº?Al2O3) was prepared by the melting method. The wastewater from the semicoke plant (WWSCP) was extracted multiple times with an isometric of di-Me carbonate (DMC)-cyclohexane mixed solvent at room temperature to obtain an organic phase (OP) with a high concentration of phenols. Ether (OPCP) was obtained by catalytic conversion of OP over catalyst Na-CH3ONa/çº?Al2O3 at 210æ³C and reaction time of 2.5 h. Both OP and OPCP were analyzed with a gas chromatograph/mass spectrometer (GC/MS) and quadrupole exactive orbitrap mass spec trometer (QPEOTMS). The results showed that only DMC, phenol, o-Cresol and other monohydric phenols were detected in OP, and only other saturated ethers such as anisole and O-methylanisole were detected in OPCP. Through the study of the catalytic conversion of WWSCP-related model compound, it was found that Na-CH3ONa/çº?Al2O3 could effectively activate (deprotonate) phenol into phenate, and the strong nucleophilic oxyanion of phenate would attack the Me carbon and carbonyl carbon on DMC to obtain Me and methoxy groups. Thereby, phenate can be combined with Me and methoxy groups to acquire the product anisole. In addition, the catalyst Na-CH3ONa/çº?Al2O3 was found to still have high catalytic activity after 10 repeated cycles. It was speculated that this was related to the abundant microporous and mesoporous structure of the catalyst Na-CH3ONa/çº?Al2O3. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Recommanded Product: 578-58-5
