Reaction Steps
To a 2 liter 4-necked reaction flask equipped with a stirrer, Dean Stark trap, condenser and nitrogen sparger were charged dodecylphenol (524 g, 2.0 m), trioxane (60 g, 0.66 m) and tetraethylene pentamine (TEPA) (189 g, 1.0 m). The temperature was raised slowly to 110° C. at which time water evolution began. After 8 hours the temperature had risen to 115° C. and water evolution ceased (42 cc's of water were collected). The mixture was cooled and filtered to yield 730g of a dodecylphenol-TEPA product containing 9.1% nitrogen.
