| description |
The transesterification reaction of sucrose and fatty acid methyl esters to produce sucroesters was experimentally evaluated using commercial emulsifiers as compatibility agents. Reactions were carried out at temperatures between 100 and 140°C, using emulsifier concentrations in the range of 5 to 15 %wt, and potassium carbonate as catalyst. Fatty acid methyl esters consumption and sucroesters production was monitored by HPLC analysis of samples. Methyl esters conversions around 40 % were obtained with 68 %wt monoester content in sucroesters mixture. Despite the reaction times were reduced by operating at high temperatures and high emulsifier’s concentration, multiple substitution and color degradation were observed. Higher productivities of sucroester and higher selectivity to monoesters were obtained when potassium palmitate was used as contacting agent. The lower monoester content in the final product was obtained when using a commercial sucroester emulsifier. Results of this study can be used for preliminary process design in a solvent-free production of biobased sucroesters. |

Las reacciones se llevaron a cabo a temperaturas entre 100 y 140°C, usando concentraciones de emulsionantes en un rango entre 5 y 15%p, y carbonato de potasio como catalizador. El consumo de ésteres metílicos de ácidos grasos y la producción de ésteres de sacarosa fueron seguidos por HPLC. Se obtuvieron conversiones de palmitato de metilo alrededor del 40% y ésteres de sacarosa de 68%p de monoéster. A pesar de que los tiempos de reacción se reducen operando a altas temperaturas y altas concentraciones de emulsionante, se observó que el producto final sufría degradación de color. Las mayores productividades de ésteres de sacarosa y la mayor selectividad hacia monoésteres fueron obtenidas cuando se usó palmitato de potasio como agente de contacto. El menor contenido de monoéster en el producto final fue obtenido usando éster de sacarosa comercial. Los resultados de este estudio pueden ser usados por diseño conceptual preliminar en la producción libre de solvente de ésteres de sacarosa biobasados.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ingenieríahttps://revistas.unal.edu.co/index.php/ingeinv/article/view/61432Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónOrjuela, Alvaro and Gutierrez, Maria Fernanda and Suaza, Andrea and Rivera, Jose Luis (2018) Production of sucroesters using solvent-free reactive systems containing emulsifiers.
