摘要
以3 羟基苯甲醛为原料,通过硝化、醚化、氧化、还原等过程,找出制备中间体5 甲氧基邻氨基苯甲酸的较佳条件。在吡啶中,5 甲氧基邻氨基苯甲酸和对甲苯磺酰氯反应,得到荧光发射波长为590nm的荧光剂6 甲氧基 2 [5 甲氧基 2 (4 甲苯磺酰氨基)]苯基 4 苯并口恶嗪酮,并配制油墨:黏度54 3Pa·s,黏性4 71,细度11μm。适应于轮转胶印印刷。
Methoxyanthranilic acid was prepared from 3 hydroxybenzaldehyde through nitration, etherification,oxidation and reduction,and then the new fluorescent agent 6 methoxy 2 [5 methoxy 2 (4 methylbenzenesulfonamido)]phenyl 4 benzoxazinone with maximum emission wavelength of 590 nm was synthesized by adding 4 methylbenzenzsulfonyl chloride to 5 methoxyanthranilic acid in pyridine.The ink was prepared(viscosity 54 3 Pa·s,stickiness 4 71 and fineness 11 μm),suitable for rotary off set printing.
