Reaction Steps

A 500 ml four-neck flask was initially charged with 30 g of paraformaldehyde at room temperature in 100 ml of isopropanol. 142 g of molten n-octadecylamine were added rapidly. The flask contents were heated to reflux and stirred under reflux for 30 minutes. 76 g of trimethylhydroquinone were added in 3 portions within 15 minutes. The mixture was stirred under reflux for 30 minutes. In the course of cooling to room temperature, a solid precipitated out and was filtered off with suction through a D3 suction filter. The filter residue was washed repeatedly with heptane. Subsequently, the residue was dried overnight in a vacuum drying cabinet at 50° C. and 100 mbar under nitrogen atmosphere. 186.4 g of product were obtained.
