    Abstract: The invention relates to a method for removing formic acid from a mixture that contains formaldehyde, trioxane, water and formic acid, by distillation. According to said method, at least one tertiary amine and/or an imine or a mixture thereof capable of deprotonation and conversion to a salt is added, prior to or during distillation, to the mixture in a catalytic amount or in an amount sufficient to form the salt with the entire amount of formic acid, and the formic acid/amine salt is removed in a liquid phase in the distillation sump.

    Abstract: Procedimiento para la preparación de soluciones de compuestos orgánicos, polimerizables por radicales libres, sensibles a la radiación, en el cual a) un primer compuesto de partida que presenta un grupo haluro ácido, y b) un segundo compuesto de partida que presenta un grupo hidroxilo de alcohol, son esterificados entre sí en un solvente o en una mezcla de solventes; y en el cual el solvente son una o varias cetonas con un punto de ebullición por debajo de 150 °C a presión atmosférica (1 bar) o la mezcla de solventes está compuesta por estas cetonas en al menos el 50 % en peso respecto de la cantidad de solventes; y uno de los dos compuestos de partida presenta al menos un grupo sensible a la radiación y el otro de los dos compuesto de partida presenta al menos un grupo etilénicamente insaturado, polimerizable por radicales libres, en cuyo caso el compuesto orgánico, polimerizable por radicales libres, sensible a la radiación, es un fotoiniciador polimerizable que puede incorporarse a la cadena polimérica de los copolímeros mediante copolimerización por radicales libres, realizándose la esterificación en presencia de al menos una amina orgánica terciaria y añadiéndose después de la reacción agua en una cantidad para que se forme una solución saturada del haluro de amonio orgánico en agua y esta solución acuosa saturada se separe de la fase orgánica, midiéndose la cantidad de agua de tal manera que la cantidad necesaria para la formación de una solución saturada no exceda en más del 10 % en peso de la cantidad teóricamente necesaria.
