A method of manufacturing an octane-boosting fuel additive, the method comprises reacting n-butyraldehyde, iso-butyraldehyde, or a combination comprising at least one of the foregoing with glycerol in the presence of an acidic catalyst to obtain an octane-boosting product mixture comprising 2-propyl-5-hydroxy-1,3-dioxane, 2-isopropyl-5-hydroxy-1,3-dioxane, 2-propyl-5-hydroxymethyl-1,3-dioxolane, 2-isopropyl-5-hydroxymethyl-1,3-dioxolane, or a combination comprising at least one of the foregoing.

Octane-boosting fuel additives, method of manufacture, and uses thereof

A method of manufacturing a cetane-boosting fuel additive includes reacting formaldehyde and 2-ethylhexanol at a mole ratio of 10:1 to 1:1, or 5:1 to 1.5:1, or 4:1 to 2:1, or 3.5:1 to 2.5:1 in the presence of a heterogeneous acid catalyst at a temperature of 300 to 375&#xb0; K to obtain a cetane-boosting product mixture comprising HC(CH)CH(CHCH)CH(OCH)OH, HC(CH)CH(CHCH)CH(OCH)OCHCH(CHCH)(CH)CH, or a combination thereof, wherein n has an average value of 2.8 to 3.2, preferably an average value of 3.
