Reaction Steps

Dimethylol octylphenol was prepared by the base (lithium hydroxide 93% and TEA 4%) catalyzed condensation of octylphenol (1 mole) with 50% aqueous formaldehyde (2 moles). The dimethyloctylphenol product was dissolved in toluene/benzene at 65% solids. Morpholine was added in one charge, and the reaction mass was refluxed to completion and vacumn dehydrated to the desired softening point and methylol content of less than 1%. This value for methylol content includes methylol groups and benzylic ether bridges.
