In this work, self-condensation reaction of 2-methylfuran (2-MF) and its cross-condensation reactions with furfural (FUR), 2-pentanone, and n-butanal have been implemented to produce C14-C15 fuel precursors. Sulfonic acid catalysts with and without alkyl chain linkers supported on fibrous nano-silica (KCC-1), MCM-41, SBA-15, and silica nanoparticles were synthesized and investigated for these reactions. Among the synthesized catalyst, sulfonic acid-functionalized KCC-1 (KCC-1SO3H) and 3-((3-(Trimethoxysilyl) propyl) thio) propane-1-oxy-sulfonic acid-functionalized (KCC-1APSO3H) showed higher conversion and selectivity for the self-condensation and cross-condensation reactions respectively. The effects of various parameters on the activity and selectivity, such as reaction time and temperature were studied. The catalysts retain their acidity over multiple reaction cycles.
