Embodiment 1
[0019] In a 1000ml autoclave equipped with a stirring bar, add 1-nitroanthraquinone (12.65g), selenium powder (0.158g), H 2 O (400ml), NaHCO 3 (4.2g), the pH value of the reaction system was about 8; carbon monoxide was introduced to 5MPa, then heated to 150°C and stirred for 3 hours, cooled to room temperature, suction filtered, and dried to obtain the target product 1-aminoanthraquinone. The product was analyzed by high performance liquid chromatography and the yield was 95.53%.
Embodiment 2
[0021] Other experimental method and condition are the same as embodiment 1, only change time, record 1-aminoanthraquinone productive rate as follows:
[0022] time (h) 1 2 4 5 6 Yield(%) 94.92 94.36 95.46 95.15 98.97
Embodiment 3
[0024] Other experimental method and condition are the same as embodiment 1, only change temperature, record 1-aminoanthraquinone productive rate as follows:
[0025] temperature(℃) 120 130 140 160 Yield(%) 87.64 95.07 95.15 95.26
