Resumo: | Biodiesel is a renewable and biodegradable biofuel, generally produced by the fatty materials transesterification. Due to its importance in the diversification of the energy matrix of countries, various studies have been carried out to improve its production process. One of the technologies developed is the use of co-solvents in the process. The co-solvents decrease the mass transfer resistance between the oil and the alcohol during the chemical reaction. In this paper, a review of the literature on the biodiesel production using co-solvents was presented. The research gathered information about various studies that are relevant to the theme, aiming to show the state of the art, the substances most used as co-solvents, and the conditions of the process variables that result in high yields of fatty acid methyl esters (FAME). In the homogeneous basic catalysis of vegetable oils, potassium hydroxide is the most used catalyst. Its range of application normally varies from 0.5% to 1.8% in relation to the mass of oil. The reaction time may vary from 10 minutes to 2 hours, the temperature from 25 °C to 100 °C, the molar ratio (MR), from 3:1 to 12:1, and the amount of 30% (w/w) co-solvent, or in some cases up to 0.7:1 co-solvent to alcohol molar ratio. |

Debido a su importancia en la diversificación de la matriz energética de los países, se han realizado varias investigaciones para mejorar su proceso productivo. Una de las tecnologías desarrolladas es el uso de cosolventes en el proceso. Los cosolventes disminuyen la resistencia de transferencia de masa entre el aceite y el alcohol durante la reacción química. En este artículo, presentamos una revisión de la literatura sobre la producción de biodiesel utilizando cosolventes. La investigación reune un compendio de información sobre varios trabajos relevantes, con el fin de mostrar los avances de investigación, de las sustancias más utilizadas como cosolventes y las condiciones de las variables del proceso que dan como resultado altos rendimientos de ésteres. En la catálisis básica homogénea de aceites vegetales, el hidróxido de potasio es el catalizador más utilizado. Su rango de aplicación generalmente varía de 0,5% a 1,8% con respecto a la masa de aceite. El tiempo de reacción puede variar de 10 minutos a 2 horas, la temperatura de 25 °C a 100 °C, la relación molar de alcohol a aceite de 3:1 a 12:1 y la cantidad de cosolvente hasta 30% (p/p), o en algunos casos, hasta una proporción molar de 0,7:1 de cosolvente a alcohol.O biodiesel é um biocombustível renovável e biodegradável, obtido geralmente pela transesterificação de materiais graxos.
