Abstract
Procedimiento para la preparación de lactosilurea de grado de pureza elevado, propia para la alimentación de los rumiantes en nitrógeno, según el cual se condensa la lactosa y la urea en presencia de agua y de un catalizador ácido, caracterizado porque se opera la condensación entre 70 y 110º C con una cantidad de agua mínima aunque suficiente para que la consistencia de la mezcla reacciona permanezca fluida bajo agitación pero sea igualmente bastante firme para que se puede depositar la mezcla sin que se cuele sobre una superficie plana horizontal.
