Synthesis of Poly Lactic Acid from Lactic Acid Using Direct Polycondensation Method Using Al(DS)3 and AlCl3 Catalysts
No full textPoly 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\u27s 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℃
ISOLASI FITOSTEROL DARI BAWANG MERAH (Allium cepa L.)
No full textShallot is one of the kitchen spices that is often used by the community. Shallot contains several useful compounds and one of them is phytosterol. Along with the development of science and technology, phytosterol can be used to reduce blood cholesterol levels and prevent heart disease, so it is very beneficial for human health. In this study, phytosterol compounds were identified and isolated. The dried onion was then pureed and sifted to 100 mesh. The sieved powder was then extracted by reflux extraction method within 6 hours. The results of the extract were then isolated by column chromatography and identified by Thin Layer Chromatography (TLC). The TLC test used -sitosterol as a standard and anisaldehyde reagent as a stain appearance. The TLC plate which had stained appearance was then analyzed using the TLC Scanner method. The results of the TLC test showed that the extract of positive red onion was purple and contained fitosterol. The results of the TLC Scanner also show that the peak and spectrum of the samples were the same as the standard -sitosterol and positively contained fitosterol

Comparison of Polylactic Acid Polycondensation Using LASC Fe(DS)3 Catalyst and FeCl3 Metal Catalyst
Full text linkPolylactic acid (PLA), also known as lactic acid, has become a promising candidate as a renewable resource for plastic production. The use of PLA as a plastic material can significantly reduce the problems caused by waste. In the production of Polylactic acid (PLA), there are byproducts such as water, while metal Lewis such as Fe (III) used in PLA production can rapidly decompose and be deactivated by water. This research aims to synthesize a water-resistant Lewis catalyst by Fe (III) Lewis metals with a surfactant called Sodium dodecyl sulfate (SDS), which will bond together to form Fe (III) dodecyl sulfate [Fe(DS)3]. This catalyst will then be compared to FeCl3 metal catalysts in terms of performance in PLA synthesize using the polycondensation method. The water-resistant Lewis catalyst is characterized using Fourier Transform Infrared (FTIR), X-Ray Diffraction (XRD), and Thermogravimetric Analysis (TGA). As for the PLA synthesized with Fe(DS)3 and FeCl3 catalysts under the same operating conditions, it is analyzed using viscometry to determine its molecular weight, Fourier Transform Infrared (FTIR), and X-Ray Diffraction (XRD). The results of the analysis of the LASC catalyst include: 1) FTIR spectra of Fe(DS)3 and SDS show similarity in stretching and bending vibration bands. 2) Crystallinity indices of 36.81% and 15.82% are obtained for SDS and Fe(DS)3, respectively. Results of the PLA analysis include: 1) The optimum temperature is 180 ℃, as it leads to an increase in molecular weight, while at 200 ℃, degradation occurs, resulting in a decrease in molecular weight. 2). FTIR result shows that lactic acid polymerization was achieved. 3) XRD analysis shows gentle diffraction from 10° to 26° which similar with literature. 4) The yields of PLA molecules synthesized by Fe(DS)3 gain with higher molecular weight compared to FeCl3 catalyst
Optimization of Polycondensation of Polylactic Acid Using Al(DS)3 Catalyst
Full text linkPoly(lactic acid) (PLA) is a promising candidate as a renewable resource for plastic production. The use of PLA as a plastic material helps alleviate issues associated with waste. In the production of Polylactic Acid (PLA), by-products such as water are generated, and the Lewis acid catalyst used in PLA production is susceptible to rapid decomposition and deactivation by water. This research aims to optimize PLA polymerization using a water-resistant catalyst, Al(DS)3, to achieve an optimum PLA molecular weight.The synthesized PLA is then analyzed using viscometry to determine its molecular weight. Optimization is carried out using the Response Surface Methodology (RSM) with a Central Composite Design (CCD) matrix. The molecular weight of the synthesized PLA is measured through viscometry, and the data is input into Minitab to obtain the optimum point. This optimum point is further validated by calculating the error value from the optimization results. The optimized PLA results in a molecular weight of 10.313 g/mol with an error value of 4.47% at a catalyst concentration of 0.15% and an operating temperature of 180 °C
