Phthalic Anhydride → Phthalic Acid

Participants

Reaction Steps

Phthalic anhydride (52 g) was added to 2-octyldodecanol (90 g) and the mixture was stirred and heated to 140° for 1 hour and then rapidly to 190° for 10 minutes and then cooled. The mixture was filtered to remove excess phthalic anhydride and any phthalic acid formed, yielding 2-(2'-octyldodecyloxycarbonyl)benzoic acid (110 g).
