“…3. The oil palm used as the raw material for this lignin isolate is an angiosperm plant and falls into the hardwood category, according to [11]. Thus, lignin consists of guaiacyl and syringyl units in certain proportions, depending on the type of wood, wood age, growth location, and climate.…”

The aim of this study was to investigate the effect of using a microwave in synthesizing Sodium Lignosulfonate (SLS) surfactant made of Oil Palm Empty Fruit Bunches (OPEFB) which contains lignin as the content to be processed, especially in the sulfonation process. The observed variables are the NaHSO3 concentration ranging from 0.1 M to 0.7 M, reaction time ranging from 30 minutes to 90 minutes, and microwave power ranging from 300 W to 750 W. on the yield and comparing the results of SLS synthesized with microwave to those obtained through conventional heating methods in the sulfonation process. The process encompassed several steps, including drying, milling, delignification, lignin isolation, and sulfonation using microwaves. Afterward, the SLS results were subjected to analysis through FTIR and HLB testing. The findings revealed a positive correlation between NaHSO3 concentration, reaction time, microwave power, and the yield of SLS Product, with the optimal conditions being at the NaHSO3 concentration of 0.7 M, microwave power of 600 W, and reaction time of 75 minutes. Moreover, the microwave method demonstrated greater efficiency in increasing the SLS Product yield by up to 24% compared to the conventional method.

“…Lignin‐based polymers have been used as dispersants in cement paste, pesticide formulas, water coal slurry; as emulsifiers for asphalt; as lubricants for the oil drilling recovery process; as dispersing and filling agents in paint, ink, dye, pigment and ceramic, and so on. The lignin agents used to improve the particle dispersion primarily include lignosulfonates, sulfonated alkali lignin, enzymatic hydrolysis lignin and kraft lignin . Generally, organosolv lignins are not as easily modified as kraft or alkali lignins.…”

However, organosolv lignins are usually sulfur free and insoluble in water, and thus can be straightforwardly precipitated by diluting with water from the spent cooking liquor.…”

Organosolv fractionation (OF) is a promising method for lignocellulosic biomass biorefining to produce biofuels, biochemicals, and biomaterials. The fractionated polymeric components may be good feedstocks to produce bio‐based materials such as green polymers via chemical or biological conversion. However, related work to specify the bio‐based materials production via organosolv fractionation of lignocellulosic biomass is relatively scarce. In this work we have provided a comprehensive review of typical organosolv fractionation for isolating cellulose, hemicelluloses, and lignin, as well as the high value‐added monomer chemicals and functional materials derived from the fractionated components and their potential applications developed in recent years, primarily including the modified cellulose fibers for polymer materials, cellulose nanocrystals (CNCs), polysaccharide‐derived platform precursors for synthesis of bio‐based polymers, lignin‐derived dispersants, surfactants, carbon materials, and hemicellulose‐derived functional materials, etc. This work suggests that organosolv fractionation of lignocellulosic biomass could be a good entry to biomass refinery for high value‐added and functional materials production. However, there are still many challenges that should be overcome in terms of the fundamental, technical, and economic aspects for the organosolv fractionation process, formation of precursor compounds, synthesis of the bio‐based materials, design of product properties and functions, and the integration of the entire process. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd

Sodium lignosulfonate (SLS) is one of natural surfactant that can be modified from lignin. The utilization of natural surfactant of SLS is widely studied by researchers. This paper will study the synthesis of a natural surfactant of SLS from rice husk lignin by ultrasound assisted – sulfonation and the characteristics of SLS based on FTIR spectra. The reaction was carried out at the temperature of 60 °C and the time of 30 minutes. From the experiment can be concluded that sulfonation process with ultrasonic irradiation has advantages compared with conventional heating, i.e. lower temperature, shorter time and higher yield.
