Reaction Steps
A separable flask equipped with a thermometer was charged with 10 parts by mass of 1-naphthol, 5 parts by mass of formaldehyde, 1 part by mass of p-toluenesulfonic acid, and 30 parts by mass of methyl isobutyl ketone. The mixture was reacted at 50° C. for 5 hours with stirring to obtain a 1-naphthol/formaldehyde condensate. The condensate had an Mw of 890 and a dispersity (Mw/Mn) of 1.4.
