ABSTRACT:
A process for the preparation of lactosylurea and the N-methylol derivative thereof which are usable as feed supplements for ruminants.
According to this process, lactose and urea are heated to 70.degree.-110.degree. C. with a minimum of water and, if possible, this water is eliminated during the reaction. The crude reaction product can be purified by grinding with ice-water or ethanol and subsequent draining so as to eliminate by dissolution in such solvants the unreacted urea.
The corresponding N-methylol derivative is obtained by the reaction with formaldehyde.
