Abstract:

The chemical components of fatty acid in monomer acid were determined by GC/MS. After the sample was etherified via methanol, the chemical ingredients and their relative contents of fatty acid in it were analyzed by GC/MS. Fifteen components (such as Myristic acid, Palmitic acid, Oleic acid and Stearic acid ) were identified. The analyzed results showed that the Tetradecanoic acid content reached up to 12.16%, the Hexadecanoic acid accounted for 8.51%, the Octadecenoic acid arrived at 25.53% and the Octadecanoic acid 32.72%. The production technology of biodiesel from monomer acid, using p-toluenesulfonic acid as catalyst, was introduced. Through orthogonal analysis of parameters in a four-factor and three-level test, the optimum conditions obtained for the esterification were molar ratio of methanol to acid 3:1, usage amount of p-toluenesulfonic acid 6% and reaction time 3h, reaction temperature 60°C.Under the optimum conditions, conversion efficiency of biodiesel with monomer acid arrived at 98%.
