Abstract

A mixture of graphite oxide (GO) and the zeolite NaY (Si/Al= 5.1) was used to dehydrate various alcohols to their respective olefinic products. Using conditions optimized for 4- heptanol (15 wt% GO–NaY (1: 1 wt/wt), 150° C, 30 min), a series of secondary and tertiary aliphatic alcohols were cleanly dehydrated in moderate to excellent conversions (27.5– 97.2%). Several primary alcohols were also dehydrated, although higher catalyst loadings ...
