When phthalic acid is heated in heptane under azeotropic reflux conditions in the presence of a catalytic amount of an arylboronic acid compound (such as 2,6-(diisopropylaminomethyl)phenylboronic acid or 2,6-bis(diisopropylaminomethyl)phenylboronic acid), phthalic anhydride is obtained in high yield.
当邻苯二甲酸在庚烷中,在存在催化量的芳基硼酸化合物(如2,6-(二异丙氨基甲基)苯硼酸或2,6-双(二异丙氨基甲基)苯硼酸)的条件下,进行共沸回流加热时,可以获得高产率的邻苯二甲酸酐。
