PERUBAHAN KOMPOSISI METIL ESTER AKIBAT KERUSAKAN PANAS PADA METIL ESTER SULFONAT DARI JARAK PAGAR

Vol 5 No 1 ABSTRACT Surfactant is a surface-active agent that can be produced by a chemical or biochemical synthesis. The most widely used anionic surfactant in surfactant flooding is linier alkyl benzene sulfonate (LAS) synthesized from petroleum material. The weaknesses of petroleum based surfac...
