Methoxymethylation of Substituted Alcohols using Dimethoxymethane over Mo(VI)/Zr02

摘要

The methoxymethylation reaction of alcohols was studied on M0/Z1O2 (MZ) catalysts. The catalyst containing 5, 10 and 15 % Mo(VI) ions was prepared by solution combustion method. These solid acid catalytic materials were characterized by NH,-TPD, powder XRD, BET, FTIR spectroscopy, scanning electron microscopy, transmission electron spectroscopy and ICP-OES techniques. These catalysts were evaluated for their catalytic activity in the synthesis of methoxymethylation reactions of various substituted alcohols with dimethoxymethane in shorter reaction times (20 min) at moderate temperature (40 °C) with excellent yields (around 99 %). The main features of the Mo/Z1O2 catalyzed reaction are high yields, ease of scale up to gram scale, recyclable catalysts, inexpensive reagents, eco-friendly catalysts and a solvent free approach for the synthesis of methoxymethylated products.
