Introduction The alkylation of phenol with alcohols and olefins is an important process used in industrial scale. Thus the niobium phosphate is also a very good environment-friendly option against the conventional solid and liquid acid catalyst. Sakthivel, A. Conventionally, the alkylation of phenol is carried out by the reaction of phenol with 1-dodecene in presence of cation-exchange resin. Keywords: alkylation, niobium phosphate, acid catalysis, phenol. Experimental General alkylation procedures The reaction was carried out in a round-bottom 50 mL 2-necked flask provided with a condenser, and a septum for sample removal. The commercial niobium phosphate present resonable value for the surface area, m 2 g Alkylated phenols are widely used as additives in gasoline, lubricants and surfactants.
The current work utilizes the ab initio density functional theory (DFT) to develop a molecular level of the mechanistic understanding on the phenol alkylation in. Procedures for alkylation of phenols follow largely those of alcohols except that weaker.

related to phenoxy acetone and phenoxy acetamide. These have. Cesium carbonate mediated O-alkylation of phenols was carried out under mild conditions to give the corresponding phenol ethers exclusively.
Results and Discussion. The intermediate from the C-alkylation is more stable and as a result, the O-alkylated products disappear gradually. So alternative way is Fries Rearrangement. Sign up using Email and Password.
