dc.description.abstract | This paper describes the physicochemical and chromatographic characterization of crambe oil and the process of its methyl transesterification via alkaline catalysis using response surface methodology (RSM). The reaction conditions developed by applying 24 full factorial central composite design were made in duplicate (obtaining the standard deviations) and the FAMEs content ranging from 75.35 to 99.85%. In the model obtained, the first order effect on catalyst percentage, temperature and reaction time showed a positive influence on the yield, however, their quadratic effects and crossed interactions resulted in negative influence. From the model obtained, a milder reaction condition with a theoretical 98.0% of FAMEs content was created and tested to evaluate its accuracy. This reaction condition present the following parameters values: oil/methanol ratio = 1:4.5; catalyst percentage = 3.5%; temperature = 38.0 °C and reaction time = 1.90 h, the experimental FAMEs content obtained was 97.8 ± 0.1%. | |
