The reactor calorimetric technique was employed to study a homogeneous, liquid-phase
ketonization reaction used in fine chemical syntheses, where an unsaturated alcohol and
unsaturated ether condense to form an unsaturated ketone with higher molecular weight. The
experiments were carried out in a calorimetric reactor (RC-1) and the data obtained allowed
the determination of reaction heat flow versus time, overall reaction enthalpy, and reaction
course for experiments at different temperatures. Using the latter data, the conversion versus
time behavior was determined. These data were modeled assuming a pseudo-first-order kinetics
and an Arrhenius-type temperature dependence of the specific reaction rate. Comparison between
these results and the usual concentration versus time experimental data obtained with a different
technique was satisfactory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
