摘要：
The production of 4-oxotetrahydro-1,3,5-oxadiazines by reaction of urea (which may be methylolated) with formaldehyde in specific molar proportions and under specific conditions of temperature and pH for not more than thirty minutes. The products are textile finishing agents and valuable starting materials for the production of textile finishing agents, particularly for cellulosic textiles.
