Pentanol is also an attractive second-generation bio-fuels and can be produced from renewable feedstock.
Most identified enhancers can be classified as: alcohols (ethanol, pentanol, benzyl alcohol, lauryl alcohol, propylene glycols and glycerol), fatty acids (oleic acid, linoleic acid, valeric acid and lauric acid), amines (diethanolamine and triethanolamine), esters (isopropyl palmitate, isopropyl myristate and ethyl acetate), amides (1-dodecylazacycloheptane-2-one [AzoneA(r)], urea, dimethylacetamide, dimethylformamide and pyrrolidone derivatives), hydrocarbons (alkanes and squalene), surfactants (sodium laureate, cetyltrimethylammonium bromide, BrijA(r), TweenA(r) and sodium cholate), terpenes (D-limonene, carvone and anise oil), sulfoxides (dimethyl sulfoxide) and phospholipids (lecithine).
1999) reported that the peroxidation products of unsaturated fatty acids were lower in the DawDam bran fraction during storage than in cultivars with LOX-3 in their seeds; the amounts of hexanal, pentanal, and pentanol in normal raw rice markedly increased during storage at 35[degrees]C, whereas in rice that did not contain LOX-3, the levels did not increase to the same extent (Figure 3).
Likewise, algal oil was transesterified using ethanol, 1-propanol, 2-propanol, 1-butanol, 1- pentanol, 1-hexanol and benzyl alcohol to produce the corresponding esters i.
El procedimiento secuencial para la obtencion de p-aminobenzoatos con metanol, etanol, propanol, butanol, pentanol, hexanol, heptanol y octanol como alcoholes primarios e isopropanol, isobutanol y 2-butanol como alcoholes substituidos (Figura 1) mediante calentamiento tradicional por conduccion a reflujo y a escala semimicro fue el siguiente: En un matraz bola de 50 mL con una junta esmerilada (14/20) se colocaron, a traves de un embudo de adicion de solidos, 2.

Sagert and Quinn (1978) have studied the effects of ethanol, propanol, butanol, pentanol and hexanol on binary coalescence of nitrogen bubbles.
