The purpose of this research is to show the processing of surfactants from bagasse with the green chemical concept that is using vegetable raw materials. This is a laboratory research method, which synthesized become sodium ligno sulfonate (SLS) surfactant using two processes, hydrolisys and sulfonation with a green chemical process that is using microwave radiation (Microwave-Assisted Organic Synthesis / MAOS). Microwave radiation is given with a power of 300 watts for 60 minutes at 80oC. This step is carried out 4 times under the same reaction conditions and reaction time for 1 hour. The measurement results of the FT-IR spectrum show that in the reaction products 1 to 4 the expected functional groups have been formed, there are three main functional groups as indicators of lignin formation, the phenolic O-H functional group, the CH-aliphatic and aromatic groups, and functional group C = C aromatic. In addition to performing functional group analysis, characterization was carried out by analyzing the structure of the lignin amination product by measuring 1H-NMR with the results of the formation of alkene groups, sulfonate groups and carboxylates. The Microwave-assisted Organic Synthesis (MAOS) method has succeeded in synthesizing contaminated and alkylated lignin derivative compounds from bagasse lignin and synthesizing lignosulfonic derivatives.
