Abstract

The fatty alcohols C8, C10, C16 and C18 were used as raw materials for the sulfation reaction using the SO3-DMF complex to study the ratio of carbon chains. The first step is to prepare the SO3-DMF complex, by reacting SO3 gas into DMF at a temperature of 0-4 0C with a reaction time of 3 hours, then sulfation is carried out at 100 0C for 5 hours on C8, C10, C16 and C18. Tests were carried out on the results of sulfation with an FT-IR Spectrophotometer. Surface tension, foam stability and yield calculations. From the sulfation results, the yield results were respectively 83%, 81%, 68% and 61% then the results from the surface tension analysis were 35.3, dyne/cm, 30.3 dyne/cm, 29.4 dyne/cm and 33.6 dyne/cm and foam stability analysis of 0.2 cm, 0.8 cm, 0.7 cm and 1 cm. Based on the surface tension reduction value, palmityl alcohol is the best raw material for making surfactants.

Abstract

The sulfation reaction between myristyl alcohol and the SO3-DMF complex has been successfully carried out to produce sodium myristyl sulfate. Formation of the SO3-DMF complex by reacting DMF and SO3 gas obtained from the reaction of phosphorus pentaoxide and H2SO4. The variables studied were the time of formation of the complex, the time and temperature of sulfation and the concentration of NaOH at neutralization. The results of myristyl alcohol sulfation with SO3-DMF were tested by FTIR spectroscopic analysis, surface tension test, and foam stability test. The formation time of the SO3- DMF complex of 5 hours is the result of the highest surface tension reduction and the most optimal foam stability. The results of the foam stability test analysis showed the highest value at 80oC with a foam stability of 0.5 cm. The best result of sulfation neutralized with 40% NaOH solution was able to reduce the surface tension value and has foam stability up to 66% with a decrease in foam height of 0.3 cm

Abstract

Empty Fruit Bunches of Oil Palm (EFB) represent one of the most problematic biomass wastes in Indonesia due to their massive volume, inefficient management, and underutilization of their chemical potential, leading to significant environmental, economic, and technical impacts. The degradation or processing of such large-scale waste generally requires a long period of time. This study focuses on converting the cellulose content in EFB into dialdehyde cellulose (DAC), which can be applied as a wet strength agent. The aim is to reduce EFB waste by isolating cellulose from EFB biomass and subsequently converting it into DAC, which can be utilized as a wet strength additive in paper or tissue products. The oxidation of EFB cellulose into DAC was optimized using sodium periodate (NaIO₄) as the oxidizing agent, with varying reaction times of 3, 6, and 9 hours. The synthesized DAC was qualitatively analyzed using the Fehling’s test and solubility observations, followed by functional group identification via FTIR and morphological characterization using SEM. Among the samples, DAC-6 exhibited the most optimal characteristics, with a degree of oxidation reaching 82.1% and a carbonyl content of 52.8%. FTIR analysis confirmed the presence of carbonyl functional groups in all DAC samples, indicating successful oxidation of hydroxyl groups in cellulose. DAC-6 showed the most prominent carbonyl absorption peak at a wavenumber of 1748 cm⁻¹.
