Cow's Fat Processing To Biodiesel By NaOH As Catalyst In Methanol
Full text linkThe research about biodiesel produced from cow's fat using sodium hydroxide (NaOH) as catalyst has been done. Biodiesel produced from cow's fat was done through transesterification process using methanol 1:12 which priory react with 0.3% NaOH as catalyst due to oil and methanol weight. The transesterification process was conducted for 5 hours at 65°C. Biodiesel from cow's fat is characterisized by GC-MS and ASTM (American Society for Testing and Materials) method. Methyl ester which produced from cow's Fat fat are 31.67% of stearic acid, 25.67% of palmitate acid, and 22.68% of oleate acid. Biodisel from cow's fat are qualified as diesel fuel and biodiesel characterisized by ASTM for specific density (0.8705 kg/m3), kinematic viscosity (4,481 mm2/s), flash point (176,5 0C), pour point (21 0C), and Conradson's carbon residu (0.0139% wt)
Synthesis Of Derivate Acetophenone From Fenol And Eugenol
Full text linkThe synthesis derivate acetophenone from fenol and eugenol had been carried out. The acylation of fenol was performed by anhydride acetate and the fries rearrangement reaction was carried out using AlCl3 catalyst at temperature of 50oC produce ortho-hydroxyacetophenone (35,29 %), purity was tested by GC, structure elucidation of these product ware analized by FTIR and 1H-NMR. Acylation reaction of eugenol was performed by anhydride acetate in base condition at temperature of 120oC for 3 h produce 5-allyl-2-hydroxy-3-metoksi acetophenone (21,42%), purity was tested by GC, structure elucidation of these product ware analized by FTIR, 1H-NMR and MS
Biodiesel Production From Bintanggur Oil (Callophyllum inophyllum L.) Using Calsium Oxide (CaO) Catalyst
Full text linkThe research of the biodiesel from bintanggur oil (Calophyllum inophyllum L.) using calsium oxide (CaO) catalyst had been done. In this study, a two-step process was used to produce biodiesel from bintanggur oil. Initially by esterification process using H2SO4 1.25% catalyst by weight of oil and methanol with a molar ratio of 1:9 and continued by transesterification process with 1:12 (oil : methanol) with the catalyst 8 wt% CaO. The esterification and the transesterification process carried out of 2 hours and 7 nespectively at a 65 °C. The synthesis of biodiesel was analyzed by FT-IR spectrophotometer. The conversion of biodiesel is 44.49%. The biodiesels properties were caracterized by ASTM method. Results of biodiesels properties there are specific gravity of 0.8878 g/cm3, viscosity kinematic 5.572 cSt, flash point 176.5 °C, pour point 9 °C, cooper strip corrosion 1b, and Conradson carbon residue 2.469%
