Acid catalysed alkylation of diphenyl ether with methanol over shape-selective zeolites
Selectivity in methylation of phenol over acidic catalysts depends primarily on temperature and the acidity of the catalyst. It is reported that direct methylation of phenol with methanol over weakly acidic catalysts yields predominantly o-cresol, whilst catalysts with medium acidity yield …

Microalgal Biodiesel Production through a Novel Attached Culture System and Conversion Parameters
… transesterification, alcoholysis, or commonly, methylation, when methanol is the alcohol used. There are several different transesterification methods. By simplifying the reaction conditions and examining the effects in terms of maximum fatty acid methyl esters (FAME) produced, we were able to …
