文摘
- •
Oligomerization reactions, strong adsorption, and reaction reversibility hinders the reaction.
- •
Extent of these undesirable processes is higher than for furfural-acetone condensation.
- •
Selectivity for C15 adduct only significant for Mg-Zr, but lower than for furfural reaction.
- •
Kinetic model considering consecutive reversible reactions yielding C9 and C15.
- •
Stability in aqueous phase conditioned by the oligomerization reactions, not by catalyst leaching.
