제조 방법
To?133 parts of ?N-(2,5-dinitrophenyl)acetamide?and 93 parts of?Phthalic anhydride?added previously melted (at 95 ℃) in 280 parts of sodium and 94 parts of sulfur crystals in and salt, this melt was heated to 130 ℃, for 10 to 11 hours. Then quickly heated to 180 ℃, heat 3 to 4 hours, until the dye detection satisfaction (BIOS 1155,33).
