反応手順
Maleic anhydride (88.3 g, 0.90 mole) and water (150.0 g) was stirred at 20°-30° C. under nitrogen, cyclopentadiene (30.0 g, 0.45 mole) was added by dropping in 1 hour and stirred at 25° C. for 6 hours and heated to 101° C. and held for 20 hours until 92% of nadic acid was converted to NBLCO2H as detected by GC. The wet crystal was filtered out and recrystallized from water to obtain 40.3 g of NBLCO2H with a yield of 49%.
