実験手順
A mixture of purified water (1.8 g) and isopropyl alcohol (40 g) was dropped to a mixture of aluminum tributoxide (24.6 g), isopropyl alcohol (60 g) and diethyl malonate (16 g). After completion of dropping, the mixture was agitated for 2 hours, subjected to hydrolytic condensation and heated to reflux for 2 hours. PGMEA (200 g) was added thereto and was concentrated under reduced pressure to obtain a PGMEA solution of an aluminum-containing condensate (B-III) (150 g). The solid content concentration of the aluminum-containing condensate was 9.9%.
