In this study, microwave induced pyrolytic oil from sago bark (SB) was subjected to esterification to improve its properties. Improvement on properties of the pyrolytic oil was performed via esterification with ethanol and the presence of sulfuric acid as a catalyst. The optimum esterification condition was studied using general factorial design. The esterified oil (EO) showed improved properties with pH (4-6), reduced moisture content (2.95-3.45%), d. (0.9-1.1 g cm-3), and acid value (39.3-123.4 mg KOH-1 g-1), and maintained the CV (20.2-21.6 MJ kg-1). GC-MS anal. showed that EO was sulfur free, and low in carboxylic acid and oxygenated compounds The optimal esterification condition with optimum quality of EO was at 65°C temperature, 60 min reaction time and 1:1 ethanol to oil volume ratio. Results indicated that the EO can be potentially used in robust combustion engines upon properties refinement. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Reference of 1731-94-8).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Reference of 1731-94-8
