"During the fatty acids reaction with methanol under the acid catalyzation, two products take place together: free fatty acids esterification and TAG interesterification during the emerging of FA methylesters and H2O and glycerols. The process both reaction and their rate was determined in the concentration range of FFA in mater 0 - 100%(w/w). Under the condition of acid catalyzation the esterification is faster. The higher temperature (over 100\u00B0C) the faster both reactions are. The water activity in thereaction mixture is decreased by distillation and so conversion degree of fatty acids is influenced by glycerol concentration."@en . "8"^^ . "610889" . .
