description A method for producing a product that comprises glycerol ketal of ethyl levulinate or propylene glycol ketal of ethyl levulinate comprises reacting either glycerol or propylene glycol with ethyl levulinate in the presence of a homogenous or heterogeneous catalyst system in a reactor system. The ethyl levulinate and either glycerol or propylene glycol are heated to remove water, polyol, and excess ethyl levulinate. The excess ethyl levulinate and polyol is recycled back to the reactor. The product is distilled in a specific fashion and optionally treated by means of a stabilizing agent or acid species removal bed, to obtain a composition comprising glycerol ketal of ethyl levulinate or propylene glycol ketal of ethyl levulinate wherein the composition comprises less than or equal to about 2 wt% contaminants. Un método para la producción de un producto que comprende cetal glicerólico de etil levulinato o cetal de propilenglicol de etil levulinato que comprende reaccionar ya sea glicerol o propilenglicol con etil levulinato en la presencia de un sistema de catalizador homogéneo o heterogéneo en un sistema de reactor. El etil levulinato y ya sea el glicerol o el propilenglicol, se calientan para remover el agua, el poliol, y el exceso de etil levulinato. El exceso de etil levulinato y el poliol se reciclan de vuelta al reactor. El producto se destila de una manera específica y se trata opcionalmente mediante un agente estabilizante o lecho de remoción de especies de ácidos, para obtener una composición que comprende cetal glicerólico de etil levulinato o cetal de propilenglicol de etil levulinato, en donde la composición comprende menos de o igual a alrededor de 2% por peso de contaminantes.
