Abstract

Inventories of petroleum fuels are increasingly depleted and will someday run out. These shortcomings can be overcome by using alternative fuels, such as ethanol. Based on this, it is necessary to research and development of ethanol as a fuel. One way is with a separation in a packed distillation column. This study aims to assess the mass transfer phenomena that occur in the process of distilling a mixture of ethanol-water-amyl alcohol packed in column. In addition, this study aims to optimize temperature and reflux to obtain the highest levels of ethanol. This research method uses packed bed distillation system with the batch process. Feed used is synthetic ethanol, water, and solvent. Solvent used were amyl alcohol. Doing distillation with heating temperature is maintained. Distillation is done in the packing of stainless steel wool. Research carried out in a batch process with a variable temperature of  79°C; 84°C; 91°C; and porosity packing 20%; 30%; 40%; 50%; 60%; 70%; 80%.

Abstract

Poly Lactic Acid (PLA) is a type of polymer that is widely researched because it can meet the requirements for biodegradable polymers and can be used in several of applications. Making PLA using the direct polycondensation method is carried out in 3 process stages, namely dehydration, polycondensation and recrystallization. Dehydration was carried out at 130℃ for 1 hour. Polycondensation was carried out at varying temperatures of 160℃, 180℃ and 200℃ with a concentration of 0.15% for 6 hours. In the meantime, 50 ml of methanol was added, and vacuum conditions were used to carry out the recrystallization process. After that, the viscosity method was used to determine PLA's molecular weight. The highest molecular weight and other properties of PLA, such as its functional groups and thermal behavior, are the aim of this study. The findings of the study indicate that PLA has its maximum molecular weight at 180°C, where it is 15576 gr/mol for PLA+Al(DS)3 and 10771 gr/mol for PLA+AlCl3. The PLA+Al(DS)3 and PLA+AlCl3 spectra display the same bands in the stretching and bending vibration modes, according to the FTIR test. Meanwhile, in the TGA analysis, the highest decomposition was shown by PLA+Al(DS)3 at a temperature of 365℃.
